Nagios Plugins and Utilities

These are all plugins or supporting utilities to work with Ethan Galstead's Nagios monitoring tool. Most plugins will also work as plugins for Tobi Oeticker's MRTG logging tool.

  • Nagios EventLog agent for Windows: To send NSCA alerts directly from filtered EventLog messages.
    • This is a Windows service that forwards filtered EventLog messages into Nagios, via the NSCA daemon. It is based on NTSyslog and send_nsca with some additional filtering code by myself, and includes the GPL libmcrypt library. It is therefore distributed under the Gnu GPL. Version 1.6.2 is believed to work with Win 2k3 but is not fully tested. v1.7.0.b now includes the missing mcvcr70.dll that is missing on some systems - it is the inclusion of these Microsoft DLLs that causes the huge size of the install package! v1.8.0 now contains a heartbeat function and upgrade option.
    • Microsoft Library Package: This may be needed to make the frontend work on some systems. Alternatively, you can pick it up from here.
