Breaking Changes

There are changes made to the pre-compiled configuration files and Get-IcingaCheckCommandConfig. Please have a look on the upgrading before applying the new configuration files.

Enhancements

• #180 Ensure check data are separated from each thread and not accessible from one thread to another to prevent conflicting results
• #193 Adds optional support for adding milliseconds to Get-IcingaUnixTime with the -Milliseconds argument for more detailed time comparison
• #198 Adds support to flush the content of the Icinga Agent API directory with a single Cmdlet Clear-IcingaAgentApiDirectory
• #203 Removes experimental state of the Icinga PowerShell Framework code caching and adds docs on how to use the feature
• #205 Ensure Icinga for Windows configuration file is opened as read-only for every single task besides actually modifying configuration content
• #207 Adds new Argument -LabelName to New-IcingaCheck, allowing the developer to provide custom label names for checks and override the default based on the check name.
• #210 Updates the Icinga DSL for building PowerShell arrays to ensure all string values are properly escaped with '. In case the user already wrapped commands with ' by himself, this will not have an effect as we only add single quotes for escaping if they are not present already
• #211 Adds feature to uninstall single components for Icinga for Windows or to uninstall everything and start entirely from new
• #213 Added support to fetch network interface for Register-IcingaDirectorSelfServiceHost directly from provided director url
• #213 Added support for Icinga Framework Code Cache file being deleted once the feature is disabled
• #213 Added support to suppress any console output for the current PowerShell session by using Disable-IcingaFrameworkConsoleOutput and to enable it again by using Enable-IcingaFrameworkConsoleOutput
• #213 Added support for -Release argument for Get-IcingaFrameworkServiceBinary suppressing questions and using GitHub as source directly if set
• #213 Added support to color console output by using Write-IcingaConsolePlain with the new argument -ForeColor
• #213 Added new feature to write Icinga for Windows console headers more easily, better structured and formatted with Write-IcingaConsoleHeader by adding line content as array elements

Bugfixes

• #206 Fixes background service check daemon for collecting metrics over time which will no longer share data between configured checks which might cause higher CPU load and a possible memory leak
• #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
• #213 Fixed ConvertTo-IcingaSecureString to return $null for empty strings instead of throwing an exception
• #214 Fixes wrong [Unknown] PluginNotInstalled exception because of new plugin configuration and wrong checking against APi result in case feature is enabled
• #215 Fixes wrong used variable for arguments on API call checks

Experimental

• #204 Adds experimental feature to forward checks executed by the Icinga Agent to an internal REST-Api, to reduce the performance impact on systems with lower resources available
• #213 Adds new experimental feature Management Console for better and easier management for Icinga for Windows and improved automation and deployed.

Issue and PRs

Bugfixes

• #186 Fixes path handling for custom local/web path sources for service binary installation

• #192 Fixes code base for Invoke-IcingaCheckService by preferring to fetch the startup type of services by using WMI instead of Get-Services, as the result of Get-Services might be empty in some cases
• #195 Fix Agent installer crash on package lookup with different files in directory
• #196 Fix Icinga 2 .conf file generator to no longer generate invalid plain configuration files
• #197 Fixes progress bar appearance on check outputs for certain plugins, by disabling the entire PowerShell progress bar during the usage of Icinga for Windows
