This is an example on how to setup an automatic downtime in Icinga using scripts.
Currently only a PowerShell script is provided here.
You will need to create an API user to allow access to the downtime functionality.
object ApiUser "downtime" {
password = "magicunicornpleasechangeme"
permissions = [
{
permission = "actions/schedule-downtime"
filter = {{ regex("^Windows", host.vars.os) }}
}
]
}
Also see Icinga 2 API permissions.
A script like this can be used to be set as shutdown script via GPO (group policy).
API and credentials can either be passed on command line, or set inside the script. The PowerShell script also contains an example to build a credential from string.
Some examples:
$cred = Get-Credential;
.\icinga-downtime.ps1 -Api https://icinga.local:5665 -Credential $cred;
.\icinga-downtime.ps1 -SkipCertificateCheck;
.\icinga-downtime.ps1 -Duration 900;
.\icinga-downtime.ps1 -HostName "this-windows-host.fqdn" -Author "Windows" -Comment "Automatic shutdown downtime";Copyright (C) 2021 NETWAYS GmbH
