Description Ryan O'Hara 2015-08-27 16:47:14 UTC

It is higly recommended to use UDP logging for haproxy. Currently, rhel-osp-director will configure haproxy to log to the /dev/log UNIX socket. Since max_dgram_qlen it most likely quite small, you will likely get warnings at startup:

[ALERT] 238/115010 (13878) : sendto logger #1 failed: Resource temporarily unavailable (errno=11)

There are two solutions:

1. Use UDP logging by changing the log line to this:

   log 127.0.0.1 local0

2. Increase the max_dgram_qlen via sysctl.

   cat /proc/sys/net/unix/max_dgram_qlen
   # probably 10

Those 3 reviews address the issue mentioned in the ticket. Both solution 1 and 2.

However, tripleo-heat-templates does not configure rsyslog daemons on the machines, hence 127.0.0.1:514 in UDP is not available out of the box.

I think this request should be made as a RFE. (ie. make t-h-t configure rsyslog deamons on the hosts)
