I don't like the standard monitoring plugins for Nagios. After hours of checking out alternatives, I finally decided to develop some own alternatives (and spend days
).
The goal was to make system monitoring simple. (And not: getting as many details as possible.)
The plugins are written in standard shell. They work on Linux and Solaris and many other Unixes. They work well with nrpe (Nagios Remote Plugin Executor).
The attached zip file contains a text file DESCRIPTION that shortly describes the functions.
With some shell writing skills it should be easy to port the plugins to other monitoring tools.
