In the server I just changed the pattern in a properties file, but I can see the agent does not have that (or I cannot find it). What would be the way to change it?</P><P>Thanks!</P> Thu, 24 Nov 2016 17:20:09 GMT christian_lutta 2016-11-24T17:20:09Z https://community.cloudera.com/t5/Support-Questions/Change-log4j-format-for-the-ambari-worker/m-p/120659#M83422 <P>Dear all,</P><P>I would like to change the output format for the log4j Ambari Agent Service.

To change the pattern, go to /etc/ambari-agent/conf and copy logging.conf.sample to logging.conf, then edit it and look for the lines</P><PRE>[formatter_logfileformatter] format=%(levelname)s %(asctime)s %(filename)s:%(lineno)d - %(message)s</PRE><P>Change the 'format' line to suit your needs. There is information on the format for this <A href="https://docs.python.org/2/library/logging.html#formatter-objects">here</A>. The available attributes that can be written to the file from each log record are given <A href="https://docs.python.org/2/library/logging.html#logrecord-attributes">here</A>.</P> Thu, 24 Nov 2016 17:29:57 GMT https://community.cloudera.com/t5/Support-Questions/Change-log4j-format-for-the-ambari-worker/m-p/120660#M83423 tstebbens 2016-11-24T17:29:57Z
