From a blog post:
Thanks for this! It saved me a lot of time.
One thing I'd suggest changing -- in Ubuntu Oneiric (and I suspect in
older versions), the rsyslogd config you specify will leave haproxy
logging in both /var/log/haproxy_1.log and in /var/log/syslog. This is
because rsyslogd writes each message out using every rule in its
configuration that matches unless specifically told not to.
The "& ~" at the end of your file /etc/rsyslog.d/haproxy.conf means
"once you've written something using the rule above, don't process any
more rules for this message". But it won't stop messages from being
written out by rules that were specified before the one in
Now, the default Oneiric config has a file called
/etc/rsyslog.d/50-default.conf which does the default configuration,
including a catch-all "write everything to syslog" rule. And because
files from /etc/rsyslog.d/ are included in alphabetical order, the
rules in 50-default.conf are applied before the ones in haproxy.conf
-- so you get your haproxy stuff dumped into both files.
The solution is obviously to call your own rsyslogd config file
something like /etc/rsyslog.d/49-haproxy.conf
