9 Best SNMP Monitoring Tools for 2018

If there is one thing that all networks have in common, it is that they need to be managed consistently in order to perform at their best. Only the best SNMP monitoring tools can help to look out for the signs of performance degradation.  The use of SNMP monitoring is easily one of the most effective ways for a network administrator to ensure the stability of the network and its connected devices.

SNMP monitoring is the practice of SNMP polling devices throughout your network and pulling information on the health of all connected devices. An SNMP monitor will be able to tell you whether a system is up, down, or compromised. By having this information at your fingertips, you can take immediate action to solve.

Keeping your SNMP monitoring constant and addressing performance issues as they occur ensures that your service stays online. You have the all-important opportunity to intercept problems before they take root and threaten your service.

Here are the best SNMP monitoring tools available on the market:

1. SolarWinds Network Performance Monitor (FREE TRIAL)

SolarWinds Network Performance Monitor

SolarWinds Network Performance Monitor is one of our top picks for SNMP monitoring in 2018. This product is adept at allowing you to monitor the health of your infrastructure regardless of whether you’re an SME or multinational corporation. There are a variety of accessible dashboard views that allow you to view whether your infrastructure is Up or in Critical condition. Problematic devices are denoted by a Warning icon.

If this isn’t enough visibility then you can use NetPath critical path visualization to view your network topology from hop to hop. With NetPath, devices are still color-coded but are shown as a topology map displaying the quality of links throughout your network. This adds an additional layer of sophistication to your network monitoring practices. This network is kept updated through an autodiscovery feature which can locate new devices once they have been connected.

Of course, even with these views, you can still miss out on key information. To resolve this SolarWinds Network Performance Monitor has its own SNMP alerts system that allows you to create trigger conditions so that you receive a notification via email or SMS once something happens. The end result is a product that ensures you stay on top of all current developments.

There is a multitude of pricing options available based on elements. For instance, NPM SL100 offers 100 elements for the price of $2,955 (£2,266). NPM SL250 offers 250 elements for $6,720 (£5,154). NPM SL500 supports 500 devices for $10,445 (£8,012). If you need more elements then you can purchase NPM SL2000 with 2000 elements for $19,345 (£14,839). There is also NPM SLX which offers unlimited devices for $32,545 (£24,964). You can download SolarWinds Network Performance Monitor on a 30-day free trial.

2. Paessler PRTG Network Monitor (FREE TRIAL)

Paessler PRTG Network Monitor

Another top-of-the-range SNMP monitor is Paessler PRTG Network Monitor, a Windows-based network monitoring tool that offers SNMP and ICMP polling to help you check up on the status of your connected devices. This platform has its own network discovery feature where you can scan for devices by IP range. Scanning for devices in this way means that you don’t have to waste time with manual configurations.

One of the strongest features of PRTG Network Monitor is its alerts and notifications system. It allows you to do the basics like sending notifications to an email or SMS but also allows you to write your own notification scripts with the API. When combined with custom notification triggers this really allows you to structure your own monitoring environment however you like.

It is worth mentioning that the quality of visualization and displays in PRTG Network Monitor is second to none. While some displays and sensors can be a little daunting at first, once you get used to them you can read them in seconds. Visualization on PRTG Network Monitor includes color-coded dials, graphs and network maps. PRTG Network Monitor offers users a scalable pricing structure. If your needs increase, then you can simply move up to the next bracket of the pricing plan. This means there is little to no risk of outgrowing PRTG Network Monitor.

PRTG Network Monitor offers a freeware option for small businesses who need less than 100 sensors. The normal price range starts from $1,600 (£1,227) for PRTG with 500 sensors. PRTG 1000 can be purchased for $2,850 (£2,186) with 1000 sensors. The next largest versions are PRTG 2500 which is $5,950 (£4564) for 2500 sensors and PRTG 5000 for $10,500 (£8,056) with 5000 sensors.

3. Zabbix

Zabbix

There are few open source network monitoring tools that deliver as compelling a user experience as Zabbix. Zabbix operates through a web-GUI. This tool uses SNMP and IPMI so that you can monitor the health of devices such as routers and switches for signs of poor performance. The Zabbix agent is well-designed with basic displays that help you to find the exact data you need.

In terms of SNMP monitoring capabilities, Zabbix SNMP support is available from devices with v1, v2, or v3 SNMP agents. This tool allows the user to collect SNMP in two ways: SNMP polling mode or the snmptrap daemon utility. Combining SNMP polling with SNMP traps provides you with complete visibility over SNMP-enabled devices.

When it comes to configurations, Zabbix is as simple as you want to make it. You can autodiscover devices to see not just when new devices are added or removed but when configuration changes occur as well. This simplicity carries over to monitoring templates as well. You can use out-of-the-box monitoring templates to help you or you can design your own configurations. The out-of-the-box templates are great for new users while more experienced users can design their own configurations from scratch.

While Zabbix offers a strong overall design it has been known to experience difficulties coping with networks with over 1,000 nodes. As such this means its best for smaller businesses. Zabbix can be downloaded for free on CentOS, Debian, Oracle Linux, Red Hat Enterprise Linux, and Ubuntu. You can download Zabbix directly from their site.

4. Nagios XI

Nagios-XI-1

Nagios XI is well-known for its diverse SNMP monitoring capabilities. As one of the most popular network monitoring products on the market, Nagios XI delivers a solid agentless monitoring experience with SNMP. You can view network healthsend SNMP traps, and monitor resources like Windows Event Logs to stay on top of day-to-day events.

This tool is also very easy to use. This is showcased by its use of configuration wizards. Configuration wizards take you through the process of setting up monitoring for a variety of devices and services. For instance, there is a Linux SNMP wizard that shows you how to monitor a Linux workstation or server. These eliminate the guesswork from using Nagios XI and help to speed along the onboarding process.

The only drawback with Nagios XI is that it doesn’t have an autodiscovery feature. This means that you’re forced to manually configure your network. While this isn’t a dealbreaker it is certainly less convenient than some of the alternatives on this list with autodiscovery.

Nagios XI is available on Microsoft (through VMWare or Virtualbox), Linux and VMware. The price of Nagios XI starts from $1,995 (£1,530) for the standard edition. The other version of Nagios XI is the Enterprise edition which is available from a price of $3,495 (£2,681). This includes scheduled reporting, capacity planning reports, and web-based server console access. You can also download Nagios XI on a 60-day free trial.

5. ManageEngine OpManager

6. OpenNMS

OpenNMS

OpenNMS is another excellent open source SNMP monitoring tool. OpenNMS has been designed to monitor network performance by collecting data through the use of SNMP, WMI, JMX, NRPE, and XMP. The SNMP polling abilities of this tool have the ability to make sure your infrastructure is in good health. You can also use SNMP data to discover new devices throughout your network.

While OpenNMS’s design is easy to use, it feels outdated when compared to the top products on this list. However, that doesn’t stop it from delivering a first-rate monitoring experience. Like all of the top SNMP monitoring tools, you can configure alarms to notify you in the event a key service goes down. You can also configure alarms by threshold so that if a device’s usage moves above or below a predefined parameter it will let you know.

Visualization is one area that OpenNMS performs very strongly. There are a variety of visual displays such as graphs, pie charts, and maps which help to show you the key trends across your network. There is even a heatmap function so that you can look to see if there are any weak points in your network connectivity. This provides you with a more comprehensive perspective when it comes to time to troubleshoot.

Overall this is a program you should definitely consider if you want to monitor your network on a budget. OpenNMS can be installed on CENTOS, RHEL, Debian, Ubuntu, Windows Server, and Docker. If you’re interested in downloading OpenNMS you can get it for free directly from their site.
