Zabbix AIX 5L : proc.num have a strange behavior

[vinz]

Hi all,

On an AIX 5L box (other seems to have no problem),
I defined an item to verify TNS Listener process in ORACLE like that :

proc.num[tnslsnr,ora920p,all,LIST_AUTOSYS]

Return of a ps is :

ora920p 3371100 1 0 Nov 19 - 0:58 tnslsnr LIST_AUTOSYS -inherit

Sometimes (often), proc.num will return 0 but the process execution date show that the process never stop... have you an idea of what happening ?

The Zabbix Queue is very low, no network problem, I probe it every minutes... i don't understand.

I've another server where I defined the same item but for an another DB, it do the same strange things...

Have you an idea ?

Thx,

I wanted to bump this back to the top, I still have this issue with AIX, and it is starting to become an issue. I don't have a good test environment for 1.5.x, can someone verify if it's been fixed or if it is still an issue with 1.5?

A little update for the developers, we have Compuware ServerVantage for our larger p570 based IBM systems that have a similar counter to proc.num. The older agent had the same behavior that I see with Zabbix where it counts one less process than is actually running. The new agent they just released has fixed this issue. The issue only started occuring after an upgrade to AIX 5.3, and I have not been able to recreate this issue on my older 5.2 boxes. I know the bulk of the work is on 1.6, but we are still looking at months of having 1.4, and this issue is causing me some headaches in moving forward.

I have no idea why this happens so far.

Just some fuel for the fire. I wonder if this issue is AIX 5.3 specific. We use Compuware ServerVantage for our large p570 systems, and Zabbix for our smaller client site machines. Since the upgrade to AIX 5.3, ServerVantage has the same strange behavior that Zabbix does in mis-counting the number of processes by 1. Has anyone had any luck in getting this type of issue resolved?

Guys,

I am with a similar problem here with AIX 6.1 and zabbix 1.8.3 agent

if I use proc.num[tnslsnr] it works, look ps -ef output

ps -ef| grep tns
oracle 802964 1 0 17:20:25 pts/0 0:00 /u01/app/oracle/product/10.2.0/db_1/bin/tnslsnr LISTENER -inherit

But... if I try to monitor ora_pmon_orcl it doesn't work !!!! Look the ps -ef output...

ps -ef| grep pmon
oracle 286926 1 0 16:49:08 - 0:00 ora_pmon_orcl

The only deference that I found is that the tnslsnr has a PATH in it and ora_pmon_orcl NOT.

I did a test with others processes that has a PATH and it worked...

Any idea ... how to monitor ora_pmon_orcl ?
