Subject Re: Review Request 21806: Disable conntrackd-stats logging to prevent it from filling up /var

no longer restarts on log rotate unless conntrackd was already running (6b7f91d7). I suppose
this wouldn't be bad to put in as well, so long as we know that conntrackd will in fact get
started when we want it (redundant virtual router). Another issue contributing to it was that
we had split up the tiny disk into many partitions, leaving only a few hundred MB available
and stranded across many parts of the file tree, since there are times when we want conntrackd
we should probably have a system vm template that can handle its logfiles.

Thank you for your response. I see your commit on the logrotate script. Although that alone
would fix it I agree with you that fixing it both ways is more reliable. :)
I will create a but report as requested.

Regarding your comment on disk space we had issues with that as wel. Not so much for /var
but in fact /usr (review 21696 CLOUDSTACK-6716). In my opinion having a lean and mean svm
is fine. A better solution, when it comes to logging, would be to send it to the control ip
with syslog. We're working on a patch that gives you the opportunity to do without losing
local logging. I'll include you in the review request one i've finished it.

stats logging is disabled by default but the config parameter is set to on. The consequence
for ACS is that a conntrackd-stats.log file is created during the build of the svm. This logfile
gets rotated by logrotate which has a post action to restart conntrackd. Even if the svm is
not a redundant router. On vpc routers for instance the stats logging file can grow quickly
and fill up the /var volume killing the vm.
