snmp management software cisco

Many SNMP software packages are available, ranging from programming In some devices, such as Cisco routers, the agent software is built into the device. Third-party network monitoring tools can use SNMP to monitor certain parameters. This document will outline the dashboard configuration and. To monitor Cisco devices, SNMP access is all that is required. If Active Discovery and monitoring is not working, the possibilities are. WWWW GETMAIL

Increased visibility into your network infrastructure can help you identify failures in critical services and applications that were caused by the network. For example, you observe an alert informing you that a critical server is unavailable. If you have configured network monitoring, you would also observe an alert informing you that a port is offline.

When you view the computer vicinity diagram for the server, you see that the unavailable computer is connected to the offline port. Thus, you can focus on troubleshooting the root cause for the unavailable computers. Operations Manager can show you how your network is connected to the computers you are monitoring through the Network Vicinity View dashboard. Using Network Vicinity View, you can see how your topology is laid out, as well as the health of each network device, computer, and the connection between each.

For a complete list of supported devices, see Network Devices with Extended Monitoring Capability spreadsheet. The devices worksheet includes processor and memory columns for each device to indicate whether Operations Manager can provide extended monitoring for either or both aspects for each device.

System Center - Operations Manager introduced a Network Monitoring Management Pack generation tool to help you create a custom management pack to add extended monitoring support for new network devices, without the need of Microsoft device certification. Additionally, this tool enables you to add monitoring of additional device components such as fan, temperature sensor, voltage sensor and power supply.

You can download the tool and user guide from the Microsoft Download Center. This tool is also supported with newer releases of Operations Manager. Ports that are connected to a computer are not monitored; only ports that connect to other network devices are monitored. You can monitor a port that is connected to a computer that is not agent-managed in the same management group by adding the port to the Critical Network Adapters Group.

Memory - including high utilization, high buffer utilization, excessive fragmentation, and buffer allocation failures for some certified devices. Some monitoring capabilities are disabled by default. For more information, see How to configure monitoring of network devices. Network discovery and monitoring requires the following management packs, which are installed with Operations Manager:. There are additional management packs that are required to relate network devices to each other and to the agent computers they are connected to.

Network monitoring requires discovery of the network adapter for each agent computer, which is performed by the management pack for the agent computer's operating system. Verify that the management packs from the following list are installed for each of the operating systems in your environment.

Windows 8 and 8. Windows 10 Client Operating System. Network device discovery is performed by discovery rules that you create. For instructions on creating a discovery rule, see How to discover network devices in Operations Manager and How to configure network device discovery settings. When you create a discovery rule, you designate a management server or gateway server to run the rule. Each management server or gateway server can run only one discovery rule. You may need to strategically place management servers on different network segments so that they can access the network devices that they are discovering.

Discovery rules run on a schedule that you can specify, and you can also run a rule on demand. Each time the discovery rule runs, it attempts to find new devices within its definition or changes to devices that were previously discovered. A discovery rule can perform explicit discovery or recursive discovery. Explicit discovery - An explicit discovery rule will only attempt to discover those devices that you explicitly specify in the wizard by IP address or FQDN.

It will only monitor those devices that it can successfully access. If you use recursive discovery, you can elect to discover all the other network devices that the specified SNMP v1 or v2 device knows about or only network devices that are connected to the specified SNMP v1 or v2 device that are in a specified IP address range. You can also filter recursive discovery by using such properties as the device type, name, and object identifier OID.

Operations Manager can identify connected devices in a recursive discovery that use an IPv6 address; however, the initial device that is discovered must use an IPv4 address. This will not only give you an idea of what packages are out there, but also help you decide what might be right for you keep in mind, though, that these pros and cons are merely our opinions.

Whenever possible, we present both open source solutions and commercial products. This chapter presents a broad survey of some of the leading products in each of these categories. In some devices, such as Cisco routers, the agent software is built into the device itself and requires no installation. On other platforms, such as Windows NT, you may have to install the agent as part of an additional software package.

Before you can look at what types of agents you need, you must research what types of devices you have on your network and what types of information you would like to receive from each. Some agents are very basic and return only a limited amount of information, while others can return a wealth of information. To start, determine whether you need to receive information from servers Unix, Windows NT, etc.

Generally, out-of-the-box network-type devices provide more information than their server counterparts. On the other hand, network devices do not extend very easily, if at all, in part because network hardware usually doesn't have a disk-based operating environment. The rest of this section provides information about some of the software packages that are currently available for use as SNMP agents. TIP: Make sure that you understand what kind of software is running on your servers email systems, accounting packages, etc.

Many applications will not listen or respond to SNMP requests, but will send out traps. Traps can be very useful for monitoring some of these applications. Also, there are applications for virus scanners, remote logins pcAnywhere , and UPSs that will send informative traps when an error has been found. Look for this feature the next time you purchase any package or software suite.

Pros Includes an snmptrap program and an HP agent that gives some additional functionality mostly for HP systems. The agent is extensible using a subset of ASN. Cons Cost is per device. You have to keep track of multiple daemons. Pros Available free for most recent versions of Solaris.

The cheapest of these is Free and the two paid plans are called Pro and Enterprise. Both of these paid services are charged for by subscription per host with an option of a monthly or a yearly payment cycle. The Network Performance Monitor is also charged for per host per month or per year.

Both of these modules are available on a free trial. A network monitoring system from Cisco Systems seems to be the ideal solution for those managing a network that includes Cisco devices. The fact that this tool is free makes it even more tempting. However, there is a catch. The tool can only monitor a network that has a maximum of 80 devices. So, this would be a good choice for a small- to middle-sized company. The Network Assistant will track down and log all of your Cisco devices and it will also draw a network topology map.

The system includes status reports, both scheduled, and on-demand, and displays alerts on performance thresholds and device conditions. It will also show warranty information on each device and service life expectancy, taken from the Cisco aftersales database. One unique feature that this product has is its device access service.

Most network monitors will interpret commands and implement them on the device — actions such as implementing queuing, for example. Spiceworks can manage networks with a mix of device brands, including equipment supplied by Cisco Systems. This tool is designed for small networks, because it has a limit of 25 devices.

However, it is free to use. The company makes its money from advertising in the dashboard, so you will have to put up with that. However, it includes an autodiscovery feature, which will give you a list of your network equipment that is constantly updated.

The monitor uses SNMP to poll all devices for statuses at regular intervals and also includes the SNMP trap system that results in alert messages shown in the dashboard. Alerts can be customized. Spiceworks produces another tool, called Spiceworks Inventory , which gives you a better track on all of your devices and also includes software auditing and updating facilities.

This tool runs discovery procedures on demand. Another Spiceworks tool that would help you check on the performance of your Cisco devices is called Connectivity Dashboard. This utility is a troubleshooting tool that checks on connection statuses between two endpoints, which could be across the network or across the internet.

Either way, the feedback from this facility will identify any problems you have with your Cisco equipment. Despite being a producer of free network tools, Spiceworks provides full professional support for its network monitoring software. The company also runs an impressive user community from where you can get tips from other Spiceworks users.

Spiceworks Inventory is also available as an online service. You do need to install a data collector agent on your system. Communications between the collector and the remote management tool is all encrypted. This monitor will discover all of your devices automatically, log them in a register, and create a network topology map.

The inventory includes the make and model of each device, so you will be able to quickly identify your Cisco equipment. The tool uses the Cisco NetFlow system to monitor traffic levels and bandwidth utilization. The LogicMonitor agent will communicate with your Cisco routers, switches and wireless access points APs.

It will track the statuses of device module and card CPU availability, memory pool, and temperature. The tool has extra functionality when dealing with Cisco Nexus switches. With Nexus switches, LogicMonitor can perform device configuration management as well as monitoring. In addition to monitoring CPU and memory statuses, the monitor can track supervisor card status and redundancy states, ejector and line card statuses, FRUN status and power draw, VDC status, fan performance, and temperature.

LogicMonitor is available in three service levels: Starter, Pro, and Enterprise — none of which are free. However, you can get a day free trial of LogicMonitor. Zabbix is a great free network monitor that can be extended to have specific functionality. The standard monitoring system uses SNMP, so you get device discovery, status polling, and alerts with this monitor. The templates available for Cisco equipment give you channels to connect directly to Cisco devices, query them, and update their settings.

There are templates for all types of Cisco equipment, including firewalls. These templates are available for free from the user community. The dashboard for the service is very attractive and it is also customizable. You get a network map page, which is updated automatically from regular SNMP status reviews.

You also get a device inventory in the dashboard. Equipment statuses and events are displayed on the screen in text and also in color-coded charts and graphs. The monitor ships with several standard reports, but you can also write your own, or get them from the user community. Unlike other free network monitors, there is no limit to the number of devices that you can monitor with Zabbix.

However, you can pay for support , which is available in five service level packages: Bronze, Silver, Gold, Platinum, and Enterprise. These include network traffic analysis, forecasting features and anomaly detection for intrusion prevention. Our list includes tools that are suitable for small networks and others that would be good for large systems. Some would work well for companies of any size. You also need to pay attention to the providers of your network equipment.

If all of your network equipment comes from Cisco Systems, then you could use any of the monitors in this list. If you have devices from other manufacturers, you would probably be better off avoiding the Cisco Network Assistant. Your other considerations when selecting a monitoring tool should be budget and number of sites and servers. Most of the software in this list can monitor WANs and include Cloud-based services.

However, some, such as PRTG charge for their software per site and per server. You will discover that SolarWinds and ManageEngine produce other infrastructure management tools that integrate with the utilities explained in this guide. That expandable operability could be an advantage for you if you need to monitor mobile devices, add on help desk functions, or add specialist monitoring tools for virtualization or security devices. Enjoy your search for a new monitor for your Cisco devices. Now you know the best tools to focus on, the time pressure is off and you can make the most of the free offers of these recommended tools to really put them through their paces.

According to the International Organization for Standardization ISO , the five important aspects of network management systems are:. Cisco Active Advisor performs an on-demand network sweep to compile an asset inventory. Try the Cisco Business Mobile App. This provides management and monitoring tools for wireless networks.

There are many Cisco device and network monitoring tools on the market and it would take you a long time to check all of them out.

We show you the best Cisco Network Monitoring Tools on the market. Stephen Cooper. This monitor uses SNMP to report on problems with devices made by a wide range of providers, including Cisco. Datadog Cisco Monitoring A network device monitor that is able to extract information from Cisco Meraki routers and switches using SNMP and by examining the event logs produced by the equipment.

Cisco Network Assistant A free network monitor produced by Cisco Systems that can monitor devices provided by that company. Spiceworks Network Monitor A free, ad-supported network monitor that has excellent live performance data visualizations.

LogicMonitor A cloud-based network monitoring service that includes device health monitoring and network traffic metrics. Zabbix A free network monitor with a good front end that features great live network device status graphs. The best Cisco network monitoring tools What should you look for in a Cisco network monitoring tool?

We reviewed the Cisco network monitoring software market and analyzed tools based on the following criteria: The ability to monitor the statuses of Cisco network devices The capability to communicate with the Cisco-friendly traffic sampling protocols NetFlow and IPFIX Monitoring other supplier devices as well for multi-vendor environments Performance metric logging for historical analysis Alerts for performance issues An interface that includes data visualizations, such as graphs.

The agent is able to communicate with Cisco network devices, such as switches, routers, and firewalls through the SNMP system. All devices manufactured by Cisco Systems ship with the agent software installed on it. The Site24x7 Infrastructure service provides the SNMP Manager role — through the Site24x7 agent that is installed on a server connected to the network.

The agent uploads the responses from device agents over an encrypted connection to the Site24x7 server for processing. This displays live performance data on the system console, which is resident in the Cloud. Users can access the dashboard through any standard browser. If a device agent notices a problem with the piece of equipment that hosts it, it sends out a Trap message. Site24x7 interprets this into an alert, which appears in the dashboard.

These warnings can also be forwarded to technicians by SMS, email, voice call, or instant messaging post. The Network Monitor of Site24x7 has a second method for communicating with Cisco devices. This is through the NetFlow language, which enables the monitor to gather traffic throughput data.

This information is sent to the Site24x7 server, which checks the data flow volumes against the potential capacity of the equipment. If limits are being reached, the service generates an alert. You can get it on a day free trial. Datadog is a cloud-based platform that offers a range of monitoring tools for IT services.

The system is charged for by subscription and includes a menu of packages. The service includes more than integrations, which can be added on for free to enhance the capabilities of the monitoring system. One of those integrations is a special service to monitor Cisco Meraki products. The tool is able to communicate with Cisco switches and routers to gather traffic statistics and it also receives alerts from devices that have status problems.

The Datadog Cisco Meraki monitoring service includes a log collection function. This can be exploited more effectively when combined with the Datadog Log Management module. Other services that can be added on include an application performance monitor and synthetic and real user monitoring for websites. Datadog is available on a day free trial.

ManageEngine OpManager is another network monitoring tool that can monitor devices from various vendors including Cisco. Like Solarwinds NPM, it also supports features like automatic network discovery, availability and performance monitoring, and various reporting capabilities. With additional licenses, network traffic analysis and configuration management can also be enabled. One of the really cool things about ManageEngine OpManager is its customizable dashboard feature, allowing you to configure the user interface with exactly what you will like to see.

It can be installed on Windows and Linux operating systems. There is a live demo of OpManager on their site to really get a feel for what it looks like and how it works. We highly recommend you can also download a free day trial or a free-forever edition that allows you to monitor 10 devices with limited functionality.

WhatsUp Gold is one of the network monitoring tools that have been around for a long time even though interest in the product went down a couple of years ago. WhatsUp Gold uses Point-based licensing where different monitored elements are assigned points e. It supports the following features:. The Cisco Network Assistant supports up to 80 devices and therefore, is targeted at small to medium sized businesses. The fact that it is free you only need to login to download it is also a bit surprising knowing that Cisco generally does not do free things.

It can be installed on Windows and Mac operating systems. Network Monitoring is a very important aspect of managing a network because not only can it alert you when something goes wrong, it can also help during troubleshooting and for network planning.

The choice of the tool you use to monitor your Cisco devices will depend on factors like cost, complexity and robustness. We recommend donwloading their 30 Day Unlimited Trial and starting monitoring within 10 minutes of installing. They have a Great Auto Discovery feature that will assist you in scanning your network for Cisco Devices and automatically add them to your inventory.

If you're looking for other options, PRTG Network Monitor is an all-in-one solution and might be less expensive for your network if you are on a budget. The Cisco Network Assistant is more fitting as a network management tool even though it also provide some monitoring capabilities not at the same level as the other tools mentioned. All the tools we discussed in this article are commercially available even though Cisco Network Assistant is free.

When compared against open source network monitoring tools, these commercial software have the advantage of being to a more probable extent supported and updated by their developers. These commercial vendors may also be able to provide expert engineers to assist with issues and troubleshooting if they arise.

WINSCP VS FTP

Sets the maximum amount of time for which the SNMP notification log entries remain in the system memory. In this example, the system is configured to delete entries in the SNMP notification log that were logged more than 20 minutes ago. The display of Interface Indexes lets advanced users of SNMP view information about the interface registrations directly on a managed agent. An external NMS is not required.

Configuration of Long Alias Names for the interfaces lets users configure the ifAlias the object defined in the MIB whose length is restricted to 64 up to bytes. Use Cisco Feature Navigator to find information about platform support and software image support.

Perform this task to configure the IF-MIB to retain ifAlias values of longer than 64 characters and to configure the ifAlias values for an interface. The description for interfaces also appears in the output from the more system:running config privileged EXEC mode command. If the ifAlias values are not configured using the snmp ifmib ifalias long command, the ifAlias description will be restricted to 64 characters.

If the ifAlias values are not configured using the snmp ifmib ifalias long command, the ifAlias description for SNMP set and get operations is restricted to 64 characters, although the interface description is configured for more than 64 characters by using the description command. Displays the Interfaces MIB ifIndex values registered on your system for all interfaces or the specified interface. The following example lists the MIB module instance identifiers registered on your system.

The resulting display could be lengthy. Only a small portion is shown here. The following example shows output for the Interfaces MIB ifIndex values registered on a system for a specific interface:. The following example shows output for the Interfaces MIB ifIndex values registered on a system for all interfaces:.

To save the snmp-server ifindex persist command, enable the snmp service using any of the snmp server config commands, except the snmp-server ifindex persist command. The interface-specific ifIndex persistence command snmp ifindex persistence cannot be used on subinterfaces. A command applied to an interface is automatically applied to all subinterfaces associated with that interface.

Testing indicates that approximately 25 bytes of NVRAM storage are used by this feature per interface. There may be some boot delay exhibited on platforms with lower CPU speeds. After ifIndex persistence commands have been entered, the configuration must be saved using the copy running-config startup-config EXEC mode command to ensure consistent ifIndex values.

Use the snmp ifindex clear command on a specific interface when you want that interface to use the global configuration setting for ifIndex persistence. This command clears any ifIndex configuration commands previously entered for that specific interface. Note that the syntax of the interface command will vary depending on the platform you are using. With this configuration, providers can provide network management services to their customers who then can manage all user-VPN devices.

In this procedure, the Event MIB is configured to monitor the delta values of ifInOctets for all interfaces once per minute. If any of the samples exceed the specified threshold, a trap notification will be sent. This section provides a sample configuration session using a network management application on an external device. The setany commands given below are executed using the SNMP application. These are not Cisco command line interface commands.

It is assumed that SNMP has been configured on your routing device. In this configuration, the objective is to monitor ifInOctets for all interfaces. If any of the samples exceed the specified threshold of 30, a Trap notification will be sent. Creates a trigger row in the table with john as the mteOwner and 1 as the trigger name.

Sets the mteTriggerFrequency to This means that ifInOctets are monitored once every 60 seconds. Sets the Rising Threshold value to Note that a row would already exist for john. To confirm that the above configuration is working, ensure that at least one of the interfaces gets more than 30 packets in a minute. This should cause a trap to be sent out after one minute. Prints messages to the screen whenever the Event MIB evaluates a specified trigger.

These messages are given in realtime and are intended to be used by technical support engineers for troubleshooting purposes. In this procedure, the Event MIB is configured to monitor delta values of ifInOctets for all interfaces once per minute. Depending on your release, note that the Event MIB feature is enhanced to add command line interface commands to configure the events, event action, and trigger. To configure the Event MIB, you need to set up a list of objects that can be added to notifications according to the trigger, trigger test, or event.

To configure the Event MIB object list, you should be familiar with the Event MIB objects and object identifiers, which can be added to notifications according to the event, trigger, or trigger test. Optional Starts a wildcard search for object identifiers. By specifying a partial object identifier, you can obtain a list of object identifiers.

By configuring an event action, you can define the actions that an application can perform during an event trigger. The actions for an event include sending a notification, setting a MIB object and so on. You can set the event action information to either set or notification.

The actions for the event can be configured only in event configuration mode. Configures object for action notification. When the object specified is modified, a notification will be sent to the host system. Configures object for action set. When the object specified is modified, a specified action will be performed. By configuring an event trigger, you can list the objects to monitor, and associate each trigger to an event. Perform this task to configure trigger parameters for the test existence trigger type.

Present—Setting type to present tests if the objects that appear during the event trigger exist. Absent—Setting type to absent tests if the objects that disappear during the event trigger exist. Changed—Setting type to changed tests if the objects that changed during the event trigger exist. The value for the Boolean comparison test can be set to unequal, equal, less, lessOrEqual, greater, or greaterOrEqual.

Sets the delta rising threshold to the specified value when the sampling method specified for the event trigger is delta. Sets the delta falling threshold to the specified value when the sampling method specified for the event trigger is delta. Note that these commands are not Cisco command line interface commands. In the following configuration, a wildcarded expression involving the addition of the counters ifInOctects and ifOutOctects are evaluated.

When an entry is created in the expNameTable, it automatically creates an entry in the expExpressionTable. Specifies the object identifiers used in the expression mentioned in the above set for calculation. Here, the number "9", suffixed to the object expObjectID, corresponds to the unique identifier used for identifying the expression, and the number "1" following "9" is another unique identifier used for identifying an object within the expression. Set the expObjectID to the two objects used in forming the expression.

There are two types of sampling: a Absolute b Delta. Here, the sample type has been set to "Delta". Specifies whether the expObjectID is wildcarded or not. In this case, both the expObjectID are wildcarded. Sets the rows in the expNameTable to active so that the value of the expression can be evaluated. You should be familiar with expressions, object identifiers, and sampling methods before configuring Expression MIB.

Optional Limits the maximum number of dynamic instance entries for wildcarded delta objects in expressions. For a given delta expression, the number of dynamic instances is the number of values that meet all criteria to exist, times the number of delta values in the expression. Configures the sampling interval for objects in the expression if the sampling method is delta. The object number is used to associate the object with the variables in the expression. Optional Configures the discontinuity properties for the object if the object sampling type is set to delta or changed.

The discontinuity object ID supports normal checking for a discontinuity in a counter. Using the wildcard keyword, you can enable wildcarded search for objects with discontinuity properties. Using the type keyword, you can set value for objects with discontinuity properties. Using the wildcard keyword, you can enable a wildcarded search for conditional objects with discontinuity properties.

Enables the specified sampling method for the object. This example uses the delta sampling method. Delta sampling—Uses the last sampling value maintained in the application. This method requires applications to do continuous sampling. The configuration permits any SNMP manager to access all objects with read-only permissions using the community string named public.

This configuration does not cause the device to send traps. The following example shows how to permit SNMP access to all objects with read-only permission using the community string named public. The device will also send ISDN traps to the hosts The community string named public is sent with the traps.

The following example shows how to allow read-only access for all objects to members of access list 4 that specify the comaccess community string. No other SNMP managers have access to any objects. The following example shows how to configure a remote user to receive traps at the noAuthNoPriv security level when the SNMPv3 security model is enabled:. The following example shows how to configure a remote user to receive traps at the authNoPriv security level when the SNMPv3 security model is enabled:.

The following example shows how to configure a remote user to receive traps at the priv security level when the SNMPv3 security model is enabled:. The following example shows how to send Entity MIB inform notifications to the host example. The community string is restricted. The first line enables the device to send Entity MIB notifications in addition to any traps or informs previously enabled. The second line specifies that the notifications should be sent as informs, specifies the destination of these informs, and overwrites the previous snmp-server host commands for the host example.

The following example shows how to send SNMP and Cisco environmental monitor enterprise-specific traps to the address The following example shows how to enable the device to send all traps to the host example. The following example shows a configuration in which no traps are sent to a host. The following example shows how to enable a device to send all informs to the host example.

Triggers an event when the threshold trigger test conditions are met. Exits threshold trigger test configuration mode. Sets the minimum delta interval that the system will accept. Sets the identification number used for identifying the expression. Creates an entry in the expNameStatusTable. Sets the object to a comment to explain the use or meaning of the expression.

Here, the comment is "test expression". Sets the object expExpression to an expression that needs to be evaluated. Sets the type of sampling to be done for objects in the expression. Sets the rows in the expObjectTable to active. The value of the expression can now be obtained from the expValueTable. Optional Sets the minimum delta interval in seconds. Application may use larger values for this minimum delta interval to lower the impact of constantly computing deltas.

For larger delta sampling intervals, the application samples less often and has less overhead. By using this command, you can enforce a lower overhead for all expressions created after the delta interval is set. Enables the expression to be configured. Configures a description for the expression. Configures the expression to be evaluated. The Site24x7 Infrastructure service provides the SNMP Manager role — through the Site24x7 agent that is installed on a server connected to the network.

The agent uploads the responses from device agents over an encrypted connection to the Site24x7 server for processing. This displays live performance data on the system console, which is resident in the Cloud. Users can access the dashboard through any standard browser. If a device agent notices a problem with the piece of equipment that hosts it, it sends out a Trap message.

Site24x7 interprets this into an alert, which appears in the dashboard. These warnings can also be forwarded to technicians by SMS, email, voice call, or instant messaging post. The Network Monitor of Site24x7 has a second method for communicating with Cisco devices.

This is through the NetFlow language, which enables the monitor to gather traffic throughput data. This information is sent to the Site24x7 server, which checks the data flow volumes against the potential capacity of the equipment.

If limits are being reached, the service generates an alert. You can get it on a day free trial. Datadog is a cloud-based platform that offers a range of monitoring tools for IT services. The system is charged for by subscription and includes a menu of packages. The service includes more than integrations, which can be added on for free to enhance the capabilities of the monitoring system. One of those integrations is a special service to monitor Cisco Meraki products.

The tool is able to communicate with Cisco switches and routers to gather traffic statistics and it also receives alerts from devices that have status problems. The Datadog Cisco Meraki monitoring service includes a log collection function. This can be exploited more effectively when combined with the Datadog Log Management module. Other services that can be added on include an application performance monitor and synthetic and real user monitoring for websites.

Datadog is available on a day free trial. ManageEngine OpManager is another network monitoring tool that can monitor devices from various vendors including Cisco. Like Solarwinds NPM, it also supports features like automatic network discovery, availability and performance monitoring, and various reporting capabilities. With additional licenses, network traffic analysis and configuration management can also be enabled. One of the really cool things about ManageEngine OpManager is its customizable dashboard feature, allowing you to configure the user interface with exactly what you will like to see.

It can be installed on Windows and Linux operating systems. There is a live demo of OpManager on their site to really get a feel for what it looks like and how it works. We highly recommend you can also download a free day trial or a free-forever edition that allows you to monitor 10 devices with limited functionality. WhatsUp Gold is one of the network monitoring tools that have been around for a long time even though interest in the product went down a couple of years ago.

WhatsUp Gold uses Point-based licensing where different monitored elements are assigned points e. It supports the following features:. The Cisco Network Assistant supports up to 80 devices and therefore, is targeted at small to medium sized businesses. The fact that it is free you only need to login to download it is also a bit surprising knowing that Cisco generally does not do free things. It can be installed on Windows and Mac operating systems. Network Monitoring is a very important aspect of managing a network because not only can it alert you when something goes wrong, it can also help during troubleshooting and for network planning.

The choice of the tool you use to monitor your Cisco devices will depend on factors like cost, complexity and robustness. We recommend donwloading their 30 Day Unlimited Trial and starting monitoring within 10 minutes of installing. They have a Great Auto Discovery feature that will assist you in scanning your network for Cisco Devices and automatically add them to your inventory.

If you're looking for other options, PRTG Network Monitor is an all-in-one solution and might be less expensive for your network if you are on a budget. The Cisco Network Assistant is more fitting as a network management tool even though it also provide some monitoring capabilities not at the same level as the other tools mentioned. All the tools we discussed in this article are commercially available even though Cisco Network Assistant is free.

When compared against open source network monitoring tools, these commercial software have the advantage of being to a more probable extent supported and updated by their developers. These commercial vendors may also be able to provide expert engineers to assist with issues and troubleshooting if they arise. Installs on Windows Server. Start a day free trial.
