Anybody out there graphing CPU data?

Post by SeanLee »

Has anyone successfully graphed CPU data for windows servers? Disk Space would also be helpful... I can't seem to get it working.

I do this (CPU and disk space usage) for Windows 2000 servers.
I use SNMP:
- you need to install the SNMP service on the Windows box (not installed by default)
- you need to check some additional parameters for this service (in the Services panel), especially you need to tell SNMP to watch hardware counters in order to get info for things like CPU or disk (again this is not enabled by default) - sorry for not being very precise but I usually use French versions with different names... :wink:

Try to play with snmpwalk (Linux tool) or Getif (Windows tool) to get all the information available from the SNMP-enabled host after enabling SNMP to check that all the information needed is really provided.
Afterwards, you should use the SNMP - Get Mounted Partitions and SNMP - Get Processor Information data queries to grab the information you want.

Wonderful. I will try your suggestions to see what the results are. Also, I found a thread here that describes & fixes this problem in 0.8.3a:

It was really hard to find... perhaps phpBB needs to improve on their search capabilities ;)

Yes! Exact, you probably need this correction too.

Note also that disk usage monitoring may also necessitates to activate the following command from a Windows console on the monitored host:

Code: Select all

diskperf -y
Try

Code: Select all

diskperf -h
to see the help. But I am not sure that this is really needed. In fact, IMHO, W2k hosts are a pain to monitor!

Hi,

You may also want to download the FREE SNMP agents for Windows from http://www.snmp4tpc.com. It gives you access some very useful counters. Excellent site on how to monitor Windows boxes with loads of other FREE tools and links to tools.

Great. Got it working.

Next step-
What seems impossible is to graph multiprocessor Linux machines...
