An example for an extension (or add-on) for Xymon that is usable on every Unix like operating system, similar to the slab extension included in the official Xymon documentation.

To have something more general (/proc/slab is only available on Linux systems) I created ttime (pronounced: [tea time]).

It is a simple extension for Xymon that can be used as a boiler plate and will be used as the reference in future blog posts.

The extension demonstrates

  • how to use the ncv-backend to create custom graphs
  • write log-messages conforming to Xymon defaults
  • modularise the configuration files of Xymon to make maintenance easier


Requirements are minimal

  • bourne-shell
  • (GNU-) date
  • Xymon installation.
