We are using Haproxy HA-Proxy version 1.6.3 2015/12/25 and are trying to send all our logs to loggly. We are using rsyslog and haproxy is logging but the /var/logs/haproxy.log isn't getting sent to loggly.
in /etc/rsyslog.d/22-filemoitor.conf that is configured to look at /var/log/haproxy.log, I've tagged the messages with "tomtest" and I don't see them. Just the other system logs. HAProxy never gets there.
I can send test events "logger troubleshootingevent" and that shows up in the console. I have also set up a file monitor to look at a dummy log file and when I update that file, those entries appear in the loggly console. Very strange behavior.
The interesting thing is that if I
$ echo "HelloWorld" >> /var/log/haproxy.log
it shows up in Loggly.
