OpenNMS--You can't beat the start up price.

At Federal Mogul, we used OpenNMS as an alternative to Nagios. We used it to do snmp monitoring across several platforms, including AIX, Red Hat and HP servers. This tool was also good for monitoring system uptimes, CPU and memory utilization and also Tomcat availability and Java memory and heap dumps.
  • When we used OpenNMS you could download the base package for free and configure it fairly easily for your own environment. You can't beat that kind of price break.
  • OpenNMS had a very nice looking GUI that was easily navigated and fairly straightforward to understand and configure.
  • There were a wide variety of add-ons available for download and implementation.
  • Perhaps it was our new configuration, but OpenNMS seemed to produce a lot of network traffic. This could cause problems on networks with limited bandwidth.
  • During the discovery phase of implementation, it is very easy to get overwhelmed with the amount servers discovered in the environment. It might be better to limit the breadth of the discovery when beginning.
  • Paid support was difficult to justify to management on a product that we downloaded and implemented for free.
For the initial cost, OpenNMS is difficult to beat and the quality of the GUI is a big plus when presenting the product to management types. In a start up position or a smaller company OpenNMS could be a very valuable asset to monitor systems and maintain availability. In larger businesses where funds may be more readily available, there are products that are more easily configurable and prettier to look at--at a cost.

We're using OpenNMS to monitor our network gear across the globe. It allows our NOC to see problems quickly and engaged the proper teams within our large organization quickly when there are issues. As a result of implementing OpenNMS we've been able to improve response times and improve our customers' experience.
  • Collecting information from various vendors and platforms.
  • Displaying the information that's collected in an easily readable format.
  • Notifying us of problems as soon as they arrive so that we can address them as quickly as possible.
  • We've had a few issues with delayed alerting.
  • I haven't quite figured out how to make topologies work yet, but I haven't spent a ton of time on it either.
  • We've also had a bit of trouble importing some MIBs, but that usually boiled down to working with the vendor to make sure we had the right MIBs and dependencies.
We've been using OpenNMS for network monitoring and have been fairly happy with it. There can be a bit of a learning curve to the setup and installation which might turn some people off, but if you can work through the learning curve it's a pretty powerful tool at the awesome price of free (paid support is available).
