W32 CPU (any number of processors) Perl Script via WMI

DevilSun · Cacti User Joined: 16 Jul 2004 Posts: 166 Location: Oregon

First off, thanks to Sidewinder...this is my first time working with Perl and Cacti, so his scripts got me off to a great start. I have lots more coming, so stay tuned! (IIS, Exchange, etc).

This script connects to a remote machine via WMI and gets the requested item from it (LoadPercentage is what I use) for however many processors you specify.

Enjoy!

I assume this is a Cacti 0.8.6 bug...the people that used it in here had it in before that came out, and it seems it has a few problems. I can try exporting now that I'm using 0.8.6 if you'd like...

You could always just use the Perl script I've provided and then setup your own data and graph template, it's not all that hard.

Hi Devilsun,
I am using your script to get the CPU load on my Windows XP system. I am using cacti 0.8.6b. I imported the data and graph templates and created data source for the local host. The graph shows up, but the CPU load is always 100% . I am using the script to just get the load on one CPU. Can you help me in this?
My cacti log file says this.

10/20/2004 01:51:10 PM - CMDPHP: Poller[0] Host[0] CMD: perl C:\Apache2\htdocs\cacti/scripts/w32_query_cpu.pl 192.168.10.136 get LoadPercentage 1, output: 100

Thanks,
Jaya.

Because it probably is at 100% (most of my queries get info right at that particular time they're queried). I had to stop graphing the CPU usage on my monitoring computer because at the time it requested the CPU usage, it was in the middle of polling a ton of devices (since polling is threaded) and at that time the CPU was being 100% used.

I know this is the case in my situation, because if I play around with the number of devices per thread and thread count for the poller, occasionally I'll get a lower value.
