cron.daily jobs needed?
Now that I've knocked out a few MM bugs, other interesting trends are
emerging.
Why are the app* servers running all these in cron.daily? The
combination of these take approximately 2 hours, and show up very
noticibly on the collectd graphs. I'm not sure which ones are the
most IO-intensive for that duration - I haven't caught it during the
run to watch.
logrotate - arguably necessary, unless this is done centrally instead?
makewhatis.cron - we don't have many manpages on the app servers, and
don't change them that often. Daily? Really?
prelink - we don't start apps that often - they're mostly
long-running.
rkhunter - arguably necessary
rpm - again, daily? Unclear what this serves us. It's just a file
listing all the RPMs installed at that moment in time.
tetex.cron - looks like it'd go fast, so no big deal. But why do we
have tetex-fonts installed on the app servers?
tmpwatch - good to have
Something to consider revising after the freeze?
Thanks,
Matt
