Monitoring a Log File for a Specific String

[valek1]

Hi, I am trying to check a text file/log file works too, for a specific string, and if that string exists I want a trigger to go off, and an email to send. I have tried multiple things for the triggers, and nothing seems to work. This is my most recent attempt :

Item :
Name : Test
Type : Zabbix agent (active)
Key : log[/path/to/file,myWord]
Type of information : Log

Trigger :
Name : Test
Expression : ({Template OS Linux:log[/path/to/file].regexp(myWord)})<>0)

So basically I am trying to get the trigger to go off if "myWord" in the file exists.
If anyone has any advice it is appreciated.
Thanks.

Could you create an external script that does the grep of the log for you and returns true/false/count etc. Then you should be able to trigger off that. as long as the script returns a single value that seems to work quite well.

If anyone else reads this, and have been struggling with this like I have, this is what I did to end up making it work:

Made the item specific host I was working with log["/path/to/file"] (Zabbix Active)
Created a trigger off that item : regexp("DESIRED_STRING"), which ends up looking like this : {server_name:log["/path/to/file"].regexp("DESIRED_STRING")})
