<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">I was able to resolve some of my issues. The first thing I did was stop all logging to ES and delete all my data. Once I started logging to ES again with a json
template statement in the output rule I saw that the logs were in fact being parsed by patterndb. Also I noticed that using the “logging device-id” statement on the ASA sends over an empty PROGRAM field in syslog – so I removed that statement. Now I have patterndb
working correctly and I just have to go through and fine tune my parser rules.<o:p></o:p></span></p>
