While at first sight we’ve only included the monitoring plugins and their CheckCommand definitions, we’ve been working closely with community contributors and team members to make it easier for everyone to contribute their own command definitions.
There are certain advantanges sending your definitions upstream:

  • everyone can use and update/fix them
  • one single place for configs and documentation
  • developers may suggest updates and help with best practices
  • you don’t need to care about copying the command definitions to all your instances (because the icinga2 package already provides them)

There is a detailed wiki howto available. Looking forward to your contributions! 🙂
