[Xymon] [External] Re: WinPSClient - Client can't get local server name

Thu Nov 29 17:28:46 CET 2018

It is domain joined, and ipconfig /all does show the computer name.  I also get the proper computer name from the echo statement, just not FQDN.  I can work around that on Xymon so that wouldn’t be a big deal.  Null value is the problem.

FYI, the clientname config isn’t in the word doc.  Putting it there does work though.

Thanks Zak and Tim!

Hi

You can do it that way, it might be painful if you have hundreds of servers to configure.

The client should pick up the host name from the computer name – the sort of thing you see if you do ipconfig /all:

Possibly this only works if your Windows computer is domain joined? If so, I could make it fallback to COMPUTERNAME from the environment, what do you get for echo %COMPUTERNAME% from the command line?

If this is not available then it’ll fall back to the client name from the XML config.

In the 'xymonclient_config.xml' file have the server name as first entry. This is on the server.

<XymonSettings>
  <clientname>someserver</clientname>
  <servers>xymonserver name or IP</servers>
...
</XymonSettings>

Hi everyone,

I have one Win2008 32 bit server that I’m trying to install the WinPSClient on.  When I try to install it I get this:

C:\Program Files\xymon>powershell.exe ./xymonclient.ps1 install
You cannot call a method on a null-valued expression.
At C:\Program Files\xymon\xymonclient.ps1:934 char:81
+         if ($script:XymonSettings.clientlower -eq 1) { $clname = $clname.ToLower <<<< () }
    + CategoryInfo          : InvalidOperation: (ToLower:String) [], RuntimeException
    + FullyQualifiedErrorId : InvokeMethodOnNull

Service "XymonPSClient" installed successfully!

So I set clientfqdn and clientlower to 0 which eliminated the errors but the Xymon server never shows any information or ghost clients with the server name.  To start troubleshooting I looked at the data file produced by the client and found the server name is missing from the first line produced by the client:

client .powershell powershell XymonPS

It looks like I could define it in the script, but every time the client is updated by the Xymon server it will get overwritten as it doesn’t look like there’s a way to define it in the config file.

Any help would be appreciated.  I’m not a Windows scripter.
