[Xymon] Windows Client

[Scot Kreienkamp]

Couldn't tell  you what version of PS I was running, but it was the current one of the time.  I never saw anything but a small spike reported back to Xymon, so if you're looking there you won't see them.  I only saw them when I was watching the task manager on the server itself.  The servers were sitting between 10-15% usage generally, and would only spike when the WinPSClient ran.  This was on 2008R2 VM's on ESX4 at the time.

FWIW, I've never seen the extreme resource hog behavior some have described with WinPSClient. Now it's entirely possible there were small spikes that I didn't notice, but definitely nothing in the 30+ second range. The systems where I ran this (at a previous job) were mostly Windows Server 2008 R2 and Windows Server 2012 VMs on ESX. Generally speaking the underlying hosts were not overtaxed. For those seeing issues are you running older versions of PowerShell or Windows? Are the machines already operating at a fairly high utilization?

Cheers.

Henrik,

I would not advise anyone to go with the PS client especially in a production setting.  I had it deployed on about 20 servers and ended up going back and removing it.  It is VERY much a resource hog when it runs, pegging my servers at 100% processor for 30-60 seconds, and in my plain vanilla environment was unstable to boot.  It was some time ago so the details are a bit fuzzy but it caused some major problems for me.

Sorry for the late response.... been on vacation to San Francisco with the family.

If you are not too scared to delve into Powershell, then I would really like you to dig into the WinPSClient.

It does work - despite not having been changed for quite some time. The main problem with it appears to be that it is a bit ressource-consuming; Powershell is not the most effective scripting language.

But it is one that is supported on all current versions of Windows ...
and it does provide you with hooks into all of the Microsoft monitoring interfaces. As I understand, getting data with Powershell is just as "easy" as doing it in C#.


Regards,
Henrik
