CPU count

[ReefShark]

My manager wants me to 'monitor' the number of CPU's in every system. I think I can write something for linux to extract that data from the system, but I am somewhat Windoze-challenged and have no idea how to pull it off on the W2K servers I put in Zabbix.

Any help on this matter would be greatly appreciated.

If you mean the amount of processes running, than there are built-in functions for that.

CPU # - Registry Entry

If you read the following registry key and count the subkeys, you get the number of CPUs.

HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\Cen tralProcessor

The 0, 1, 2, 3...etc. represent the different processors. Now, without checking, this may represent the number of processors that the OS sees - not the physical number (ie. dual-core or hyperthreading may show different numbers). However, I am certain that if you check the Net, you can find a method to determine if the processor listed are physical or virtual.

Reading the registry can be done easily with VBScript via WSH, WinBatch...

This can also be achieved via WMI and VBS. Here's an example, http://vbnet.mvps.org/index.html?cod..._processor.htm

Got the linux clients working with

UserParameter=system.cpucount,grep processor /proc/cpuinfo | wc -l

Still looking into the Windows stuff.... Is there any way to get the number of CPU's present through SNMP?

CPU count

On Windows clients use the key in a host item

system.cpu.num[online]



Description - Processor Count
Type - Zabbix Agent
Key - system.cpu.num[online]
Type of information - Numeric (Integer 64bit)
Units -
Use multiplier - Do Not Use
Update interval (in sec) - 3600

As someone mentioned earlier that will give you the total number of cores, not physical CPU's

And for cores with hyperthreading enabled, each core is counted twice. New Intel CPUs (i7) are multicore AND hyperthreaded

Hope this helps

a little more efficient:

UserParameter=system.cpucount,grep -c "^processor" /proc/cpuinfo

And now you can use Zabbix Agent key:
https://www.zabbix.com/documentation...zabbix_agent?s[]=system.cpu.num

system.cpu.num
Number of CPUs.	Integer	type - possible values: online (default), max	Example: ⇒ system.cpu.num
