Package: clamav-freshclam
Version: 0.102.4+dfsg-0+deb10u1
Followup-For: Bug #904013
Dear Maintainer,
logging the timestamp inside the message break also the logcheck rules.
For example the first logcheck (ignore.d.server) rule states:
^\w{3} [ :0-9]{11} [._[:alnum:]-]+ freshclam\[[0-9]+\]: ClamAV update process started at .*$
But the message written in the logs is:
Aug 20 18:26:53 mail freshclam[15525]: Thu Aug 20 18:26:53 2020 -> ClamAV update process started at Thu Aug 20 18:26:53 2020
As you can see, the timestamp written after the process id is NOT matched by the logcheck rule.
You can solve the issue by altering all the rules, inserting a regexp to match the timestamp as follows:
^\w{3} [ :0-9]{11} [._[:alnum:]-]+ freshclam\[[0-9]+\]: \w{3} \w{3} [ :0-9]{16} -> ClamAV update process started at .*$
But the best thing, imho is to avoid printing the timestamp inside the message, since rsyslog already writes the timestamp at the beginning of the log record.
Thanks,
Luca
