process-mail logging messages should be sent to a file

[Martin Pool]

It looks like log messages from cronscripts/process-mail.py are just sent to stderr, then sent by cron to error-reports@, then ignored. :-) It would be bett<spiv> poolie: I'm not a LP person, but that sounds good to me.

<spm> I think error-reports mail spam is best for really primitive, exceptional "hey I didn't manage to run at all" errors.
<lifeless> desired behaviour is to log operational stuff to a file
<lifeless> and sysadmins-must-act-on to stderrer if they were written into process-mail.log so the logfile could be synced around etc.

In lib.canonical.launchpad.scripts.logger it looks like the default is configured to be stderr unless a --log-file option is given.

Actually it turns out at the moment we just have eg

<spm> it's more like: */5 * * * * $LP_PY /srv/launchpad.net/production/launchpad/cronscripts/send-bug-notifications.py >> /srv/launchpad.net/production-logs/send-bug-notifications.log 2>&1

Feel free to close this if you're happy with the manual redirection.

[Gary Poster (gary)]

We have three things we care about to some degree.

- gross failures of the machinery that go to stderr
- critical failures of the machinery that go to a log
- other failures and notes from the machinery that go to a log.

It seems we handle all of those identically now, which does seem a bit problematic.

I'll leave this bug open as a note to make sure that we're happy with how we handle these. I think the manual redirection is OK for now, but it is something we will want to eventually improve.
