Why the CPU data got from AIX host is 0 ?

[yjeff]

I installed the 1.8.3 zabbix_server on RedHat Linux and installed zabbix_agentd on AIX 5300-08. But the CPU data got from the AIX zabbix_agentd is always zero. Can anyone help me to resolve that problem ?

Try AIX agent 1.8.1

Hi,

I had the same problem with agent 1.8.2 on AIX 5.3 (5300-07). No CPU and memory data.

I use now agent version 1.8.1 on my AIX and everything works well.

I have a support ticket open on this.

I think you will find that if you compile your own agent on the same technology level you are trying to monitor (5300-08) that it will probably work for you then.

We have seen this problem since 1.8.2 and that was our solution, but managing multiple agents for technology levels is a major pain.

I have a support ticket open on this.

They have posted new binaries for the AIX platform on the agent download page. You might want to give these a shot. My (very) limited testing at this point is looking good... at least for the AIX 5.3 agent.

Still use 1.8.1 (instead of 1.8.2 or 1.8.3)

Hi,

I have just tested AIX 5.3 agent version 1.8.3. I downgrade to 1.8.1 after two minutes. I have the same problem as agent version 1.8.2:

• CPU information (system.cpu.util[,idle,avg1];[system];[user]) are always '0',
• Memory information are not supported (vm.memory.size[cached];[free];[total]),
• Host uptime is not supported (system.uptime).

Accuracy problems

I have no problem getting data from v1.8.1 agentd (one host at v1.8.2) installed from binaries, but the CPU utilization is not accurate. zabbix_agentd consistently and significantly under-reports CPU data (vs. SAR or nmon data). I would view any CPU numbers with skepticism. They are fine for relative comparisons, but do not assume they accurately reflect actual CPU utilization on your monitored systems.

Bernard - did you try using that enhanced AIX template I sent you in conjunction with the new binaries?

Zabbix 1.8.2 introduced new functionality based on vmstat to gather various data and also takes into consideration whether lpars are utilizing micro-partitioning. If you use this enhanced template, you would no longer be using any of the metrics from the stock AIX template that has the "avg1" variable to them in regards to CPU and memory.
