RE: Logging & rsyslogd

Put a - in front of the path in syslogd.conf.

Ie:

local0.*
-/mnt/log/haproxy_0.log
local1.*
-/mnt/log/haproxy_1.log
local2.*
-/mnt/log/haproxy_2.log
local3.*
-/mnt/log/haproxy_3.log
local4.*
-/mnt/log/haproxy_4.log
local5.*
-/mnt/log/haproxy_5.log  

That will help a lot with your load. Without the -, syslog is asked to sync the disk after every entry.    

Also, levels are incremental. Debug includes info, info includes crit, notice includes warning, etc..  

So, just list one level (ie: info) in your Haproxy config, and if you want to break it out by level then do it in your syslogd.conf.

Hello,

After enabling logging in rsyslogd & haproxy.config using the following lines, are CPU utilization has gone thru the roof. It used to be at 5-10% utilization, and it is now above 95% most of the time.

rsyslogd.conf:
# Save HA-Proxy logs
local0.*
/mnt/log/haproxy_0.log

local1.*
/mnt/log/haproxy_1.log

local2.*
/mnt/log/haproxy_2.log

local3.*
/mnt/log/haproxy_3.log

local4.*
/mnt/log/haproxy_4.log

local5.*
/mnt/log/haproxy_5.log
