Hi @sekoh
Could you please use code blocks to format your snippets.
That’s right because those are just the names of the command objects. The configuration of the check command can be found in /usr/share/icinga2/include/command-plugins-windows.conf, i. e.
object CheckCommand "disk-windows" {
command = [ PluginDir + "/check_disk.exe" ]
// ...
The actual plugins can be found on the windows host in c:\Program Files\ICINGA2\sbin.
