Maintaining the message log in Policy Minder for IBM i requires manual intervention. We recommend that you run the Purge Message Log (PRGMSGLOG) command periodically. For example, if you run your compliance checks once a week or once a month, you may want to first run the PRGMSGLOG command before doing any compliance checks. That way, the message log is cleaned up on a regular basis and you will always have the most recent messages available for reference. As of Policy Minder for IBM i 1.3, you can specify the number of days to keep information, rather than purging the entire log.
