A collection of plugins for Nagios/Icinga that we use to monitor our update infrastructure in the Public Cloud. We could not find any existing plugins for these use cases.

The script monitors a given process and if the process runs longer than the specified time it is marked as critical or optionally killed. If the kill operation fails the process is also marked as critical.
This is useful to monitor long running processes that may get stuck. One needs to have an idea about the expected run time of the process. This is not useful for monitoring time critical processes. The check can only be used on processes that have a singular instance, i.e. there can only be one entry in the process table for the process with the given name.
The script monitors that the given directory is/remains empty or does not exist
The script monitors that repositories in the given directory have valid
metadata GPG signatures (i.e., that repomd.xml.asc and repomd.xml.key match
repomd.xml).
The script checks that the expected repositories are enabled and that directories for these repositories exist. It uses a configuration file, by default /etc/rmt-utils/rmt_repository_config.json
The script monitors that files older than given number of minutes don't exist in a directory.
