Per [1], I was seeing tons of audit messages listed in logwatch reports. (My patch fixes that, btw.) My actual question is why I wasn't seeing those messages in my old (old) F20 logwatch reports, but did see:
--------------------- Kernel Audit Begin ------------------------
**Unmatched Entries** enabled 0 flag 1 pid 0 rate_limit 0 backlog_limit 320 lost 0 backlog 0 backlog_wait_time 60000
instead. Is this your experience, that some upgrade started giving tons of audit messages?
I think that previously, when logwatch looked at the logfiles, it was misconfigured to not use /var/log/audit/audit.log, but instead:
LogFile = modsecurity2/modsec_audit.log
and what I saw came from /var/log/messages (not sure why). Now logwatch looks at the journal (that's the format of the lines I see) and is actually able to report audit issues.
