SNMP-Informant-STD CPU Usage (Windows)

ajeskey · Post by **ajeskey** » Sun Apr 10, 2005 2:33 pm

This uses the SNMP-Informants Standard MIB Add-On to graph CPU stats on Windows.

You must have SNMP-Informant Standard MIB Add-On install on the Windows host you are polling in order for this to work. If you are not familiar with SNMP-Informant, it is a free download, and is extremely stable, since it does not add any services to the machine.

I have tested this on various machines from 1 CPU to 8, and they all seem very acurate.

Image to follow on the next post… the forums should let you attach more…

What it Graphs
--------------------
* Processor Time (Totally CPU Usage)
* User Time (User CPU Usage)
* Privileged Time (Operating System and all other Privileged CPU Usage)

The image labeled "informantcpu.JPG" had to be zoomed in a bit since the CPU is usualy maxed out.

"informantcpu2.JPG" should be a little better at describing what you will normaly see, well unless you run crazy number crunching applicatins like I do.

Do you have any templates for other counters like Disk, Memory etc?

ajeskey · Post by **ajeskey** » Mon Apr 11, 2005 5:53 am

There are many out there that will do what you are looking for. You should really search the forums.

If you are looking for somethat *I* have done, I posted a disk one too, that was all of 2 lines below this post. Or again it's something that would have been found by searching.

http://forums.cacti.net/viewtopic.php?t=7148

I am currently working on a Memory counter too, it will use SNMP-Informant as well.

Having a slight problem with applying your templates:

Running on Fedora Core 2,Caci 0.8.6.d,php 4.3.11,net-snmp 5.2.1-10

I get data for each CPU, (graphing dual Intels w/HT on)
but not on the CPU - |query_cpuinformInstance|.

when I do a Verbose Query test on Win32 - SNMP - Informant - CPU I get:

+ Running data query [10].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/var/www/html/cacti/resource/snmp_queries/win32_cpu.xml'

+ Found data query XML file at '/var/www/html/cacti/resource/snmp_queries/win32_cpu.xml'

I then fire up GetIf and manually query the :
cpuinformPercentProcessorTime
cpuinformPercentUserTime
cpuinformPercentPrivilegedTime

I get 5 instances , each CPU + HT and a total, but for some reason it's not graphing the total.

hmm..while I was double checking this, I noticed that sometimes the host did NOT return any data on the _Total instance..

IThe hosts I want to grap is all running Windows 2000, Microsoft SNMP + Informer Standard.

Anyone able to help me ?

It could be that you are running in "d" I still haven't upgraded.

I never use the "total_" I realize that it could be handy, but the returned value seems to be unstable coming out of SNMP Informant. But I may be speaking out of school on that (it's just my experiance)

When I finaly get around to upgrading to "d" I'll check this out.

hi

in "data queries" edit: Win32 - SNMP - Informant - CPU:

xml path need: <path_cacti>/resource/snmp_queries/win32_cpu.xml where i can find win32_cpu.xml ?

Thanks

i need to create an wn32_cpu.xml with

i have this error: "RRDTool Says:

ERROR: opening 'E:\serveurperso/rra/websattelecom_com_cpuinformprocessor_58.rrd': No such file or directory"

in the Associated Graph Templates for my host when i Turn On Graph Debug Mode.

ajeskey · Post by **ajeskey** » Wed Jun 22, 2005 9:01 pm

Well thats a good start at least you have the XML file in place now.

The file is obviously missing, or not accesable with the user account that you are running the sevice as. Does the file exist on the filesystem?

I would delete all the cpu data sources then go and recreate the graphs.

websat · Post by **websat** » Fri Jun 24, 2005 4:04 am

i delete the cpu data and try to recreate the graphs, but still have the same problem....

ajeskey · Post by **ajeskey** » Fri Jun 24, 2005 1:57 pm

I am at a loss, may want to try the genreal forums. and point people back to this thread

ajohnson · Post by **ajohnson** » Thu Dec 29, 2005 3:15 pm

You may want to try setting SNMP to V2. When set to V1, I was not able to see the CPU on my Windows box from CACTI (which is on Linux)...

This script need to be update as well for 0.8.6h, because win32_cpu.xml query result parsed by new version have invalid value. see the compare results.

old version

new version :

+ Found data query XML file at 'G:/root/web/home.ausmis.com/cacti/resource/snmp_queries/win32_cpu.xml'

the new version use "End of Mib" as instance name so cause poller.php pull the invalid data.
