hi ,
we have haproxy installed locally on a cluster of servers(centos 5.5 )
behind a layer 4 load balancer,all with the same
configuration file and log setting.
on some servers there is a mismatch between the number of
session seen in the stats uri and the amount of records in the log file ,
on others the number correlate.
for example on a problematic sever :
(log has been truncated and stats were rested at the same time)
total number of sessions from stats uri : 2111156
number of records in log file : 112834
each second the log is increases by about 50 records
while on a different server with the same load
each second the log is increases by about 1000 records.
on a correctly working sever :
total number of sessions from stats uri : 2483449
number of records in log file : 2482151
each second the log is increases by about 1000 records
the same as the session change rate.
can some one might point to the cause of the problem?
since the haproxy config is the same on all servers ,
i guess the difference is somewhere in the OS level .
below are our log config :
from haproxy config file
global
log 127.0.0.1 local0
....
defaults
mode http
log global
option httplog
.....
from/etc/syslog.conf:
..
*.info;mail.none;authpriv.none;cron.none;local0.none /var/log/messages
...
#save haproxy log
local0.* /var/log/haproxy.log
from /etc/sysconfig/syslog:
SYSLOGD_OPTIONS="-m 0 -r"
..
