  • #208 Fixes Convert-IcingaPluginThresholds which sometimes did not return proper numeric usable values for our internal functions, causing issues on plugin calls. In addition the function now also supports the handling for % units.
  • #213 Fixed possible crash on Get-IcingaAgentFeatures if PowerShell is not running as administrator and therefor the command icinga2 feature list can not be processed

  • #153 Adds support to add a knowledge base id to Exit-IcingaThrowException for easier referencing. This should mostly be used for custom messages, as we should track the main knowledge base id’s inside the messages directly.

  • #138 Fixes possible value overflow on Convert-Bytes while converting from anything larger than MB to Bytes
  • #140 Fixes version fetching for not loaded modules during upgrades/plugin calls with Get-IcingaPowerShellModuleVersion
  • #143 Fixes the annoying hint from the analyzer to check space before open brace
