[Xymon] Windows PS client svcs data missing

[Storer, Raymond]

Scott and David, I’m not finding any .net call that will produce the “StartupType” for a service that is already installed. There is a documented way to do it from a Win32 API; but, that involves using P/Invoke. See here: http://www.leeholmes.com/blog/2009/01/19/powershell-pinvoke-walkthrough/  and here: http://pinvoke.net/default.aspx/advapi32/QueryServiceConfig.html

This is what I have so far:

function XymonSvcsNET2
{
                $result = [reflection.Assembly]::LoadWithPartialName("System.ServiceProcess")
                $Services = [System.ServiceProcess.ServiceController]::GetServices()
                $COLUMNNAME="Name"
                $COLUMNSTATUS="Status"
                $COLUMNDESCRIPTION="Description"
                #[Reflection.Assembly]::Load(‘System.ServiceProcess, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’)
                #get all the services installed on the local machine
                $serviceController = [System.ServiceProcess.ServiceController]::GetServices()
                "[svcs]"
                "--------------------------------------------------------------------------------------------------------------"
                "{0,-50} {1,-20} {2,-20}" -f `
                $COLUMNNAME, $COLUMNSTATUS, $COLUMNDESCRIPTION
                "--------------------------------------------------------------------------------------------------------------"
                foreach ($svc in $serviceController) {
                "{0,-50} {1,-20} {2,-20}" -f `
                $svc.Name, $svc.Status, $svc.DisplayName
                }

}

I did get the formatting figured out finally after about 6 hours.  The only piece that I cannot figure out is the service startup type, if I can get some help on that I think this is workable.

I'm a complete newbie at powershell, so comments/help appreciated.

David, you can also use the “Load” method instead as follows:

[Reflection.Assembly]::Load(‘System.ServiceProcess, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’)

Ray,

Thanks for the code. I’m a bit wary of using something with such a version specific path though – is that seriously a “standard” interface to a .Net DLL that can be expected to have some degree of persistence?

I’m offsite this week, will try to take a look next week.

Thanks, David.

Thank you Raymond… If I knew how to implement it I would.  Hopefully David or Henrik can find the time to experiment with it.

I'm seeing all kinds of problems with the PS client…. If this keeps up I'll have to remove it.  It pegged one of my servers at 100% for over an hour, stuck on the WMI yesterday.

Opps… I missed the “.” in the [Reflection.Assembly]. Also, you can pipe it to out-null to avoid any unwanted output. So:

[Reflection.Assembly]::LoadFile(‘C:\WINDOWS\Microsoft.Net\Framework\v2.0.50727\System.ServiceProcess.dll’) | out-null

Scot and David, if you’d prefer to implement a .net pure call for services you can try the following:

# your path to the file may very
[ReflectionAssembly]::LoadFile(‘C:\WINDOWS\Microsoft.Net\Framework\v2.0.50727\System.ServiceProcess.dll’)
#get all the services installed on the local machine
$serviceController = [System.ServiceProcess.ServiceController]::GetServices()
foreach ($svc in $serviceController) {
                # should indicate: Stopped, Running, or Paused … others???
                write-host $svc.Status
                # the service name
                write-host $svc.Name
                # the service display name
                write-host $svc.DisplayName
}
