      Description

      Zabbix Server Version: 2.2.4

      On 12/4, I performed an OS upgrade to AIX 6.1.9.4 (6.1 TL 9 Service Pack 4) and rebooted the server. After rebooting the server, I noticed that the Zabbix agent was reporting higher CPU loads (I am using the system.cpu.load monitoring item). I logged onto the server, and used AIX performance tools such as topas, vmstat, and sar to research what might be causing the higher CPU load. The performance tools showed no obvious culprit. I then upgraded the Zabbix agent from 2.2.1 to 2.4.1 to see if the results would change (no change, the CPU levels still showed to be higher than what AIX was reporting).

      After being unsuccessful in my analysis, I reached out to IBM tech support. After analyzing the performance data I sent to them, IBM advised there were no issues with current system resources.

      I have attached several screenshots to this JIRA ticket to show CPU levels before the upgrade/reboot and after. I've also included some latest data screenshots that show higher CPU load than what topas is showing in AIX. If you need additional screenshots or data to help in your analysis, please let me know.
