<# .SYNOPSIS Determines the current state of the Hyper-V virtual machine. .DESCRIPTION Invoke-IcingaCheckHyperVVMHealth determines the current state of all available Hyper-V virtual machines by default. It also offers you the possibility to ex/include virtual machines with wildcard search i.e. if you enter the following ``-IncludeVms *test*`` as parameter, only ``VMs`` will be added to the check, which the name of the VMs contains this wildcard name. .ROLE ### WMI Permissions * Root\Virtualization\v2 * Root\Cimv2 ### Performance Counter * Processor(*)\% processor time ### Required User Groups * Performance Monitor Users * Hyper-V Administrator .PARAMETER IncludeVms Include only virtual machines with a specific name. Supports wildcard usage (*) .PARAMETER ExcludeVms Exclude virtual machines with a specific name. Supports wildcard usage (*) .PARAMETER ActiveVms Include only virtual machines that are currently running .PARAMETER WarningActiveVms Allows to monitor on how many active VM's are currently present and throws a warning in case it is within the threshold .PARAMETER CriticalActiveVms Allows to monitor on how many active VM's are currently present and throws a warning in case it is within the threshold .PARAMETER SkipVMHeartbeat Skips the current virtual machine heartbeat status check. .PARAMETER VmEnabledState Critical threshold for the Hyper-V VM current status .PARAMETER NegateVMState Negates the VmEnabledState of this plugin and will then report all Vms CRITICAL, in case they are not matching the VmEnabledState. .PARAMETER NoPerfData Disables the performance data output of this plugin. .PARAMETER Verbosity Changes the behavior of the plugin output which check states are printed: 0 (default): Only service checks/packages with state not OK will be printed 1: Only services with not OK will be printed including OK checks of affected check packages including Package config 2: Everything will be printed regardless of the check state 3: Identical to Verbose 2, but prints in addition the check package configuration e.g (All must be [OK]) .EXAMPLE PS> icinga { Invoke-IcingaCheckHyperVVMHealth -ActiveVms -IncludeVms '*sales*' -Verbosity 2 } [OK] Check package "Virtual Computers" (Match All) \_ [OK] Check package "vm-01" (Match All) \_ [OK] vm-01 HealthState: OK \_ [OK] vm-01 Heartbeat: OK \_ [OK] vm-01 State: Enabled \_ [OK] Check package "vm-02" (Match All) \_ [OK] vm-02 HealthState: OK \_ [OK] vm-02 Heartbeat: OK \_ [OK] vm-02 State: Enabled \_ [OK] Check package "vm-03" (Match All) \_ [OK] vm-03 HealthState: OK \_ [OK] vm-03 Heartbeat: OK \_ [OK] vm-03 State: Enabled \_ [OK] Check package "vm-04" (Match All) \_ [OK] vm-04 HealthState: OK \_ [OK] vm-04 Heartbeat: OK \_ [OK] vm-04 State: Enabled \_ [OK] Check package "vm-05" (Match All) \_ [OK] vm-05 HealthState: OK \_ [OK] vm-05 Heartbeat: OK \_ [OK] vm-05 State: Enabled \_ [OK] Check package "vm-06" (Match All) \_ [OK] vm-06 HealthState: OK \_ [OK] vm-06 Heartbeat: OK \_ [OK] vm-06 State: Enabled | 'vm01_healthstate'=5;;
