How to print previous and following lines of a matched log line ???

[gongaro]

Hello,
I'd like to create an Item and a trigger that monitor a log file with a regexp that if matched print that line, the 5 previous lines and the 5 following lines.

Is this possible?

Thanks!

I don't think you can do this with the 'native' log item, but you can create a system.run[ ] ( in the server ) or a UserParameter (in the agent conf). grep have the -A and -B options to do what you want:
1) key: system.run[ grep -A 5 -B 5 'SEARCH_STRING' /log/file/name.log
2) UserParameter:get_search_string[ * ] , grep -A 5 -B 5 '$1' /log/file/name.log
The second option is prefereable
key: get_search_string[ SEARCH_STRING ]
Please check the exact syntax... Those are just ideas
