Issue and PRs

Upgrading Steps

Reworked plugins and removed arguments

Please note that in general plugins should no longer ship % values performance data and only the actually values including thresholds and min/max input. With the new Icinga for Windows Framework, you can use your graphing solution to properly calculate % values there on your own for display context. Monitoring is for most plugins possible, by simply adding a % sign behind your threshold.

In case the plugin does not support this input for this specify argument, you will receive a UNKNOWN output.

Invoke-IcingaCheckNetworkInterface

The following arguments have been removed from the plugin and are no longer usable:

  • IncomingAvgBandUsageWarn
  • IncomingAvgBandUsageCrit
  • OutboundAvgBandUsageWarn
  • OutboundAvgBandUsageCrit

These arguments were a % value based on the link speed and the current traffic of the interface. With the new argument handling for % values with Icinga for Windows v1.5.0, you can achieve the same result with the following, already present arguments:

  • DeviceTotalBytesSecWarn
  • DeviceTotalBytesSecCrit
  • DeviceSentBytesSecWarn
  • DeviceSentBytesSecCrit
  • DeviceReceivedBytesSecWarn
  • DeviceReceivedBytesSecCrit
Invoke-IcingaCheckMemory

We entirely reworked the plugin and added the same % value shipping with Icinga for Windows v1.5.0, which means we removed the following arguments:

  • PercentWarning
  • PercentCritical

In addition we added page file monitoring capabilities to the plugin with additional arguments

Invoke-IcingaCheckUsedPartitionSpace

As for both previous plugins, we reworked used partition space with changes for % values with Icinga for Windows 1.5.0 and fixed minor issues from the ground up.

Invoke-IcingaCheckPerfCounter

We fixed a spelling issue on the command itself, which was Invoke-IcingaCheckPerfcounter before and now properly displays Invoke-IcingaCheckPerfCounter. For that reason your current plugin configuration will change.
To resolve this beforehand, rename the custom variable within your Icinga Director to match the new uppercase C for Counter, before importing new configuration baskets.
