Win2k / Win2k3 Multi CPU / Hyperthreading CPU Graphing ?

rcaston · Post by **rcaston** » Thu Sep 16, 2004 1:08 pm

Currently our company uses perfmon to watch CPU load across all windows servers, we'd like to replace it with Cacti/RRDTool

But we don't like that we must graph our HT dual CPU compaq DL360's and higher boxes as 4 different graphs (2 HT CPUs)

4 graphs doesnt really tell us the real 'cpu load' of a server.

how can you obtain this info in one graph?

I've done searching on this site and havent found a 'definitive' answer to this problem.

Well, you haven't actually said what you want the graph to look like, only what you don't want it to look like so it'll be hard to help you without that info.

Sorry about not being clear.

Basically I want a single graph that displays percent CPU load for the entire system like I can get from a Unix Box.

From a windows host, I am only able to get one graph per CPU, and in the case HT, I get 2 graphs per CPU, which makes it very hard to tell the actual 'CPU Load' of a windows server at a glance.

I'd be happy with either of the following as a solution:

1. Ideally, a total CPU load that looks identical to the ones I get from Unix boxes.

2. Or at least one graph that charts all the loads from each CPU one on graph (each cpu being a line), rather then be spread acrosss 2-6 graphs.

Here ya go, if you can use WMI

that work is awesome of yours DevilSun, but due the limitations of this environment, I really need to find a SNMP only solution if one exists...

since I am running cacti on linux.

What I have done to accomodate this is once I have created the individual DS's, I create a new graph based upon their contents. There is another approach to create a Window/XP Host template for 1, 2, 4 and 8 way systems and to create a graph template for that host that includes all CPU's.

I have done it manually to date and it works GREEAAATT on both our 4 way and 8 way boxes.

Not exactly what you may be after but you could try - http://forums.cacti.net/viewtopic.php?t=4668

One other option is to load another agent on the servers. We're currently using one from that I found at http://www.snmp-informant.com/

It allows you to poll CPU, Disk, Memory, and Network via SNMP and it's free. Works well for us. They also have an advanced agent that reports on most everything that perfmon does( it's not free but relatively cheap)

The other option for you would be to look at HP's MIB's and see what you can get from there. They may have a total CPU load as well and if you have the insight agents loaded, then they are already displaying that data.

BTW, the agent from snmpinformant seems pretty stable. I'm currently running it on about 30 Windows 2000/2003 servers with no problems at all. Planning on rolling it out to about 500+ in the next couple of months using Cacti to do the perf graphing...

Good luck!

Skaminski,

Could you post your data / graph / host templates for your SNMP-INFORMANT queries?

skaminski · Post by **skaminski** » Mon Oct 18, 2004 5:58 am

I don't think my templates will work unless you purchase the advanced agent from them. However, i can post some of my graphs when i get in the office. I don't have a problem putting anything up here to help. If you'd like the templates for the advanced agent, I'll put them up though.

I could also help you with the one for the free agent and then you could post it up. Configuring it is pretty simple.

Hey Sean.

Any help would be great. What I basically looking for is a simple template that will be able to do the core checks for a 2k/3k win server. Ie Memory, CPU, Disk and network

If you have any std ones for that, then great!

Thanks for the reply

I don't have any using the free SNMP Informant agent. Setting everything up is fairly easy though. Download and install the agent on the machine you want to monitor. Copy the MIB's from SNMP informant into your MIB folder of Getif (or whatever you use) delete the .index file and restart getif.

From within Getif, you should now be able to browse the OID Tree and will see the metrics provided via the agent. I'll post the templates for CPU Total %Utilization that I'm using. However, if you use the free version, I belive they have a differnt OID so you may have to modify the OID string so that it will work correctly for you.

After reading your post, I saw you were also looking for Disk, Memory, and Network.

For Disk and Network, I use the standard Queries SNMP - Interface Statistics and SNMP- Get Mounted Partitions. They seem to work well and since I have different servers with different NIC's and Disk configurations, these queries give me the data I need.

For Memory, I've created one similar to the CPU graph. I'll also be adding some additional memory counters related to paging and memory pools (paged and non paged)
