Michael Friedrich 17615ac444 Redis: Dump host and service state events 
fixes #5163
 2017-04-12 16:58:08 +02:00
Thomas Gelf ed2ebdf0d0 RedisWriter: publish Icinga 2 stats as a simple "keepalive" 
Use case: a reader subscribes to config changes. As they happen rarely, chances
are good that the connection will time out in the meantime. Now, a reconnect is
easy - but you wouldn't know whether you missed any config changes. So you are
required to issue a new sync to be on the safe side. Given a 60sec connection
timeout (think: SSL layer, firewalls etc) when no traffic happens this would be
too expensive.

Some kind of a heartbeat available for subscription would allow subscribers to
artificially keep the connection alive. As a first simple solution to this I'd
suggest to publish CIB data, that might be useful anyways.
