can't get haproxy to write any logs

haproxy is working great for me, but I can't get it to write any logs messages. I've censored some info by replacing it with <a_name> for privacy reasons. Any help would be greatly appreciated.

My command line is:

haproxy -dV -f <path_to_config>

I'm executing haproxy as root. I've tried setting the user and group to both nobody and root to see if that mattered. My config file looks like:


# log lots of stuff to localhost's syslog
# add the following to /etc/syslog.conf so it listens to the
messages that are sent


         log             localhost local0 debug

# run as an unprivileged user just in case
# user nobody # group nobody user root group root chroot /var/chroot/haproxy
# limit the total number of connections
maxconn 10000 ulimit-n 21000 defaults
# client timeout can be relatively short
clitimeout 5000
# set to 10 seconds longer than the longest prod qpx
calendar query srvtimeout 210000
# set to 5 seconds because tcp retransmit is 3 sec (I think?)
contimeout 5000
# retry failed connection attempts (possibly to different
backing server) retries 3 listen stats :8080 mode http stats uri /
# doesn't seem like we should need "balance" here, but it
barfs if it's not there balance roundrobin listen dashboard :80 mode tcp balance roundrobin server dash-00 <host>:10000 maxconn 1 server dash-01 <host>:10001 maxconn 1 ...

Syslogd is running and listening for socket connections:

root 17312 0.0 0.0 3684 632 ? Ss Jul15 0:02 syslogd -m 0 -r

/etc/syslog.conf contains:

# I think this will just be all of the haproxy log messages -matt local0.* /var/log/haproxy.log

My os is:

Linux r42br17 #1 SMP Tue Nov 6 09:47:40 EST 2007 x86_64 x86_64 x86_64 GNU/Linux

I ran a tcpdump:

tcpdump -A dst port 514

and didn't see any messages from haproxy to that port. Again, it's working great, I'm just getting 0 log messages. Any help would be greatly appreciated.
