Invoke-IcingaCheckCPU performance data gets swallowed

Icinga 2
1

Hello, I’ve got the problem, that I do not get any performance data when issue a check with icinga2

I’ve got the following implemented:

object CheckCommand "Invoke-IcingaCheckCPU" {
    import "plugin-check-command"
    command = [
        "C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell.exe"
    ]
    timeout = 3m
    arguments += {
        "-C" = {
            order = 0
            value = "Use-Icinga; exit Invoke-IcingaCheckCPU"
        }
        "-Core" = {
            order = 4
            value = "$IcingaCheckCPU_String_Core$"
        }
        "-Critical" = {
            order = 3
            value = "$IcingaCheckCPU_Object_Critical$"
        }
        "-NoPerfData" = {
            order = 99
            value = "$IcingaCheckCPU_Switchparameter_NoPerfData$"
        }
        "-Verbosity" = {
            order = 5
            value = "$IcingaCheckCPU_Int32_Verbosity$"
        }
        "-Warning" = {
            order = 2
            value = "$IcingaCheckCPU_Object_Warning$"
        }
    }
    vars.IcingaCheckCPU_Int32_Verbosity = 0
    vars.IcingaCheckCPU_Object_Critical = "$$null"
    vars.IcingaCheckCPU_Object_Warning = "$$null"
    vars.IcingaCheckCPU_String_Core = "_Total"
    vars.IcingaCheckCPU_Switchparameter_NoPerfData = false
}

apply Service "WinCpu" {
  import "generic-agent-service"
  notes_url = WikiBaseURL + host.vars.service.notes_url + "WinCpu"
  check_command = "Invoke-IcingaCheckCPU"
  vars.IcingaCheckCPU_Object_Warning = "75"
  vars.IcingaCheckCPU_Object_Critical = "85"
  command_endpoint = host.vars.client_endpoint
  assign where host.vars.os == "Windows" && "noNSClient" in host.vars.features
}

When I issue the check on the windows powershell on he windows host, I do get performance data out:
powershell -C { Use-Icinga; Invoke-IcingaCheckCPU -Warning 75 -Critical 85 -Verbosity 2; }

What am I doing wrong, and why are the performance data values swallowed during the transfer

Thanks from sdohn

After I had modified it accordingly, the check now works as desired with the performance data.
