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?
As you say, it's not currently implemented. But it's an interesting idea.
I think it can quickly be done, will look at it.
I have now added it. You'll need librelp 1.2.2 (not yet released, but
soon). This is the core patch:
http://git.adiscon.com/?p=rsyslog.git;a=commitdiff;h=02da275527f94c9dbc7bbfa2bc028d265867b762
The feature will be released as part of 8.1.4. Doc is here (search for
"KeepAlive"):
http://www.rsyslog.com/doc/imrelp.html
great, thanks!
think I'll wait for librelp 1.2.2 to be released before testing it,
given that you say it will be out soon,
erik
