one woraround for this would be to enable the 'mark' module on your sending systems. that will let you generate one log per minute and keep the connection from going completely idle for too long.

Subject: [rsyslog] TCP KeepAlive supported with RELP?

http://www.rsyslog.com/doc/imtcp.html mentions support of KeepAlive.

 Is this available with imrelp/omrelp? I don't see it listed in docs:

http://www.rsyslog.com/doc/imrelp.html
http://www.rsyslog.com/doc/omrelp.html

Just trying to see if KeepAlive would be a reasonable workaround for the problem we encounter when using Amazon Elastic Load Balancer which seems to cause huge delays if there is 5 minute gap in traffic.

 These do not work, tried them one by one (config error):

input(type="imrelp" port="5140" KeepAlive="on")
module(load="imrelp" ruleset="collector" KeepAlive="on")
module(load="omrelp" KeepAlive="on")
action(type="omrelp" KeepAlive="on" ...)

Given that i/omrelp modules use TCP is there some way to make them use TCP KeepAlive?

 Thanks!
