Hi, I'm totally new to ELK and logstash with Grok patterns.. I was able to parse and extract Apache logs using ( grok { match =\> { "message" =\> "%{COMMONAPACHELOG}" } }  
). but I do have one more application with different log patterns unable to extract everything from grok pattern. Could someone help me with this. below is log format

you have to write the grok parser. You can use the below link for constructing your grok parser [http://grokconstructor.appspot.com](http://grokconstructor.appspot.com)
