This goes to say that you can view any pattern based log file so long as the fields in the pattern are ones supported by log4j and Insight. Of course, you may have some issues with priorities other than debug,info,warn,error and fatal. We unfortunately don't have documentation on the entire design. The classes are well documented though. You may want to look at the following: Log4JPatternInterpeter - Creates a ReceiverFormat object from the specified pattern. You may want to customize this class to recognize RegEx patterns. LogInterpreter - Parses and creates the LogEvent instances from the log files. Internally uses multiple Apache Oro Regex pattern matching classes. The LogEvent is the data object recognized by rest of Insight and contains all the information pertaining to a n event logged by the logging framework. I hope this helps. Aken,

It's based on a log4j format. I've looked at your preference.xml and I think I can't customize it for my needs. Any chance you could lead me to some docs I could use to adapt your tool to read my logfiles? Thanks! Ive downloaded your application hoping I could use RegEx to match it to my cutom log file.

See http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/PatternLayout.html where "p" in the pattern string is defined as "Used to output the priority of the logging event." Eugene,

Althought they can be prioritized by severity, but it seems odd to call it `Priority` in the first place Note after looking at screenshot:

Please pass on your log4j.properties file and a sample log file and I can figure out the pattern for you. Note that the pattern is case and space sensitive and has to be an exact match. Nicolas,

I've been having some problems when using it. I'm setting the primary and secondary patterns, which are the same that I have configured in my log4j configuration file, and when I try to open a log file the tool would say: "specified log pattern doesnot match data in: ..." Could you tell me what I'm doing wrong? Nico Hi,

I’ve been having some problems when using it.

“specified log pattern doesnot match data in: …”

Could you tell me what I’m doing wrong?
