Network and Server Monitoring

One of my passions is automated monitoring and correction of network and server problems. I have the most experience with SiteScope (primarily a commercial website monitoring tool that has branched out to include protocols, application stacks, and whatever custom stuf you want) and Nagios, which is free and open source, and very very configurable.

I would LOVE to form a company implementing these or similar monitoring tools. I’ve done this a lot at work, and a little bit on the side for a few friends and their companies.

I’ve been looking around, and it seems that in addition to Nagios, two other contenders are Zenoss and Cacti. I’ve heard good things about Zenoss, specifically how it is easier to set up than Nagios. I think I may check it out, though I am a fan of Nagios’s flexibility.

  1. I confess that I have been getting more and more into Nagios.

    I’ve found a plugin called NagiosQL that manages the configuration much easier with a mysql back-end, yet can be removed entirely as well, since it merely writes the files. (though also can perform sanity checks and trigger restarts). I have not made use of its managing remote nagios instances (via FTP) yet, but hope to try it out soon. Curious how it does the sanity check remotely, though restarts are just writing to the command file.

    I’ve also used the NSCA plugin to report results to my standby nagios instance (failover box) so that state is maintained if we should need to failover.

    Next I am looking into NRPE so that either the master or slave nagios server can check both nagios servers with the same configuration.
