Getting error messages from log files

[luissma]

Hi,

I defined following trigger to look for "error" in /var/log/messages: Template_A:log[/var/log/messages,error].nodata(1)}=0

For the moment, it works fine; whenever the word "error" is written in the log file, Zabbix activates the trigger and a message is sent.


I have a question regarding this trigger subject: Is it possible to include error lines, extracted from log file, in the message configured in Actions?


I've been working on this for long but I'm not able to get to a solution.

Thanks in advance.

After some time playing around I found a reasonable solution for this "problem".

This is the item I use to look for new "error" entries in /var/log/messages:

Type: ZABBIX agent (active)
Key: log[/var/log/messages,[eE][rR][rR][oO][rR]]
Type of information: Log


and this, the trigger expression:
{host_example:log[/var/log/messages,[eE][rR][rR][oO][rR]].nodata(1)}=0


I created a new action triggered by these conditions:

Trigger description like "/var/log/messages" AND Trigger value = "PROBLEM"

that sends a message with this content: {{HOSTNAME}:log[/var/log/messages,[eE][rR][rR][oO][rR]].last(#1)}
