Network monitoring is one of our most requested topics on Packet Pushers, and this week we take on open source monitoring solutions. Why open source? Because commercial NMS solutions are all over the place in functionality and price. So, if it’s possible to put a solid NMS in place based on open source, then it’s worth a try. Many of us are familiar with a variety of open source NMS projects, including Zabbix and Nagios. The trick with any of these packages is that they need a lot of configuration massaging before they are useful. Out of the gate, they just aren’t all that easy to use.
Enter OMDistro.org, the central point of discussion on this show. OMD, somewhat like Security Onion, takes several different open source NMS tools, bundles them together, and adds a configuration layer that makes them relatively easy to deploy. Plus, the end resulting package is reasonably powerful. While you’ll still need to do some tweaking to get precisely what you want, OMD takes much of the pain out of the initial setup.
We have this discussion with Dominik, a Packet Pushers listener from Germany who needs to remain somewhat anonymous due to who he works with on a day to day basis. He’s done quite a bit of interesting work with OMD, and talks through it with us.
