Icinga PowerShell Plugins

1.14.1 (2026-03-31)

Issue and PRs

Bugfixes

• #471 Fixes Invoke-IcingaCheckPartitionSpace to report UNKNOWN if no usage data was used, which was previously handled by "No disk size available". As we now properly receive disk size data but still no usage data in these cases, we receive false positives
• #472 Fixes the partition size provider to no longer map the volume to partition by using the drive letter, but the device id instead, to ensure real partition size is applied for every use case

1.14.0 (2026-02-11)

Bugfixes

• #453 Fixes Invoke-IcingaCheckPartitionSpace to properly report the total size of partition, even when user disk quotas are set
• #459 Fixes Invoke-IcingaCheckHTTPStatus to make status code monitoring output working again, adds documentation for -Minimum argument and added new argument StatusMinimum to determine how many HTTP checks should return OK for the overall check to return OK (required for monitoring cluster resources for example)

Breaking Changes

• The performance metrics for Invoke-IcingaCheckScheduledTask have changed for lastruntime and nextruntime, which now store the offset from the last/next runtime to the execution time in seconds. This also means you have to update your thresholds for warning/critical for these checks, as the value will now increase over time!

Bugfixes

• #351 Fixes Invoke-IcingaCheckUpdates to properly report critical for -CritOnReboot
• #377 Fixes Invoke-IcingaCheckPerfCounter to write correct performance data in case only certain instances are checked to ensure perf data are assigned to checks accordingly
• #420 Fixes Invoke-IcingaCheckUptime to report a more human readable output for the current uptime in the package name
• #436 Fixes performance data for ScheduledTask plugin for Last and Next RunTime

Enhancements

• #389 Adds support for disk health check to Invoke-IcingaCheckDiskHealth (thanks @audiocoach)
• #408 Adds support for Invoke-IcingaCheckDiskHealth to filter disks by their friendly name
• #430 Adds support for Invoke-IcingaCheckHTTPStatus to allow for ignoring SSL/TLS errors
