What is the recommended way to manage installed Nagios (or Icinga) plugins?
At the moment all plugins on my system are installed from Debian/Ubuntu packages, so this takes care of updates, file integrity and clean deinstallation. Is there a similar way to manage plugins which are provided e.g. on http://exchange.nagios.org?
My current impression is that I have to manually download the script files from the website and place them e.g. somewhere in /usr/local/. But I have to manually check for updates and bugfixes to these scripts, I have to manually keep track of where these files were downloaded from, and I have to manually keep track of dependencies in case a plugin consists of multiple files.
Is there a better way to manage such plugins?
