Parsing inside log file

[Mahdi24322]

Hi community, 

I am actually stuck in a parameter, I have a log file that contain a line : 

number of rows = 0

and I need to monitor this value (0) if it changes to a different value more than (0) , it means that something is going wrong, I think that using DQL to create a log metrics should help, but I am stuck in this , can someone help please.

Regards

Hi @Mahdi24322 ,

You can use DPL to parse lines and test phrases.

There are some examples here: https://www.dynatrace.com/support/help/platform/grail/dynatrace-pattern-language/log-processing-line...
