Win Agent 2.2 64bit 100% CPU on Win 2008 R2 SP1

[zalex_ua]

I now have the 2.2.0 agent working on my 2008 servers. I didn't take the time to go through every single item, but I know it was one or more of the items in the 'Template Windows Baseline.'

I am using the below items from that template now and they are all working fine on all windows servers.

perf_counter[\Processor(_Total)\% Processor Time]
vm.memory.size[free]
system.swap.size[,free]
zabbix[host,agent,available]
system.uptime
proc.num[]
perf_counter[\Memory\Page Faults/sec]
perf_counter[\Memory\Page Reads/sec]
perf_counter[\Paging File(_Total)\% Usage]
perf_counter[\PhysicalDisk(_Total)\% Idle Time]
system.cpu.load[,avg1]
vm.memory.size[total]

I am also using the filesystem discovery and checking various other services.

Do you mean a "Template OS Windows" template ?
But it contains 18 items, so it's a bit different.

Well, 10 minutes ago I've linked the "Template OS Windows" to the 2008 server, see incoming data and it's still fine (~0% CPU).

...

Try to get these keys value from zabbix server one by one using a zabbix_get tool.
And watch on the CPU.

Are you sure that CPU problem appear exactly after you link the 'Template Windows Baseline' to the win host ?

After 2.2.0 release, these changes were made to windows agent:

https://www.zabbix.org/websvn/wsvn/zabbix.com?rev=40193

(is it time to advertise the websvn ? )

Unfortunately, there no compiled agent available.
I'll ask to compile it tomorrow and it will be available here http://www.zabbix.com/developers.php in Pre-2.2.1rc1 (stable)

I'll let you know when it will be available.

Now they are available to download. See "bin" folder inside archive.

So I got my 2008 R2 SP1 test box today. I used the original 2.2.0 agent for testing. My test box is a VM with only 2vCPU's and 4GB of memory.

I am not seeing the same issues as you guys reported. The only brief spike I saw was when I added the item in for System log monitoring as shown below.

I'm having the same issues with the 2.2.0 agent (2.2.1 server) on Windows 2008 servers. We were having performance issues with eventlog gathering to the Zabbix server, so I configured a new template that can filter the events at the source rather than on the Zabbix server.

So I create a template with the following entries:

Application Log eventlog[Application,,"Critical|Error|Warning"]
Directory Service Log eventlog[Directory Service,,"Critical|Error|Warning"]
File Replication Service Log eventlog[File Replication Service,,"Critical|Error|Warning"]
Security Log - Failure Audit eventlog[Security,,"Failure Audit"]
System Log eventlog[System,,"Critical|Error|Warning"]

And one (or many) of those triggered a 100% CPU spike on my servers. I'm not quite sure which one yet, I'll be investigating. Disabling the checks and restarting the Zabbix Service would immediately fix it.

Note the the CPU usage was from a svchost.exe process. This specific process according to Process Explorer hosts three services:
- DHCP client
- Windows Event Log
- TCP/IP NetBIOS Helper

I strongly suspect the Windows Event Log service is the one causing the issue here.

I'm having the same issues with the 2.2.0 agent ...

Please check the same on agent version 2.2.1
You can take it on http://www.zabbix.com/developers.php (I mentioned above)

Unfortunately it's not available currently on http://www.zabbix.com/download.php

I upgraded to server 2.2.1 using the download and from there used the agents (2.2.1).

Problem solved.
