Objet: [rsyslog] Load balancing issue
Hello all,
I'm currently trying to load balance the log traffic accross several servers.
I thought my configuration with "ActionSendTCPRebindInterval" option was
working properly, unfortunately my recent benchs show that the log flow is not
well load balanced.
Please find below a part of the architecture :
My problem is located on the log aggregators : the rsyslog send its traffic to
haproxy on localhost using relp protocol.
I monitored the tcp sessions and i can see that haproxy doesn't change the
destination servers.
watch 'ss -lap -o state established \( dport = :20514 \)'
Recv-Q Send-Q Local Address:Port Peer Address:Port
1716 0 127.0.0.1:43652 127.0.0.1:20514 users:(("rsyslogd",8409,88))
0 1138 10.17.252.4:58436 10.19.12.5:20514 timer:(on,196ms,0)
users:(("haproxy",3922
,2))
1760 0 127.0.0.1:43650 127.0.0.1:20514 users:(("rsyslogd",8409,22))
0 0 10.17.252.4:55583 10.19.12.6:20514 users:(("haproxy",3922,10))
Please find enclosed my configuration.
NB :
- the source pid (rsyslog) never change as it is expected with
"ActionSendTCPRebindInterval"
- i mixed legacy and new syntaxe because of the following bug
https://github.com/rsyslog/rsyslog/issues/96
This bug is annoying and i didn't receive any update since about 4 months
Could you please help me ?
OS : debian7
rsyslog version : 8.10
Regards ,
Smana
