Hello, I have the following two lines (they can occur multiple times) in a logfile

> 2017-05-01 09:21:35 [item\_utils.py] INFO: stock\_status value after cleanup is OUT\_OF\_STOCK  
> 2017-05-01 09:21:35 [item\_utils.py] INFO: stock\_status value after cleanup is IN\_STOCK

I want to create 2 variables (in\_stock, out\_of\_stock) to count the times of concurrence of each of the previous two lines, how to do it using grok?

Thanks

Figured it out, `%{TIMESTAMP_ISO8601} %{NOTSPACE} %{LOGLEVEL}: stock_status value after cleanup is %{GREEDYDATA:stock_status}`
