@Stephbat  To enable rotation  for the ambari-agent, follow below steps: cp /etc/ambari-agent/conf/logging.conf.sample /etc/ambari-agent/conf/logging.conf  Change the following line: args=('/var/log/ambari-agent/ambari-agent.log',"a", 10000000, 25) Where: The value 10000000 is the maximum size of the logs in bytes and the value 25 is the number of old logs to keep after the log rotates.
