User Parameters to monitor a process

[dpeterson]

Hello all,

I have set up a UserParameter in my zabbix_agentd.conf to monitor for a specific process. Here is how I have it set up:

 UserParameter=ZabJob,ps -ef | grep xyz | wc -l

I have set up the item in Zabbix and I am receiving data, however the returned value is +1 on every host.

For example:

david@host:/etc/zabbix$ ps -ef |grep xyz
5090     12354  3117  0 11:28 pts/0    00:00:00 grep xyz
david  22807     1  5 Jul06 pts/4    01:23:04 xyz


david@host:/etc/zabbix$ ps -ef |grep xyz |wc -l
2

Zabbix shows a value of 3 instead of 2. Any idea on why this might be happening?

Cheers

You have at least two options:

1) Use the command:
UserParameter=ZabJob,ps -ef | grep xyz | grep -v grep | wc -l

2) use proc.num[xyz] Item.

I can not tell why Zabbix shows 3 in the above example.

But I have another tip: to decrease the count by 1 - and to get the correct 1 instead of the 2 in the example - use a modified grep argument like this one:

 ps -ef |grep [x]yz |wc -l

This will avoid wc seing the line with the grep process itself.

Thank you very much! This worked like a charm!

Thank you for the reply!

Or use pgrep (http://en.wikipedia.org/wiki/Pgrep)
