Jean Flach	6aaa35a0a6	Rewrite the RedisWriter ... There should be more atomic commits but the whole thing was a mess. This commit changes the synchrounous Redis connection into an asynchronous one in its own class RedisConnection. The RedisConnection uses a Workqueue with commands to fire against the Redis server. When a response is required a callback must be supplied, refer to RedisWriter::RedisGet(). Known Issues: - Authentication has no error handling and can break the connection - Error handling in general is iffy due to the nature of the async redis connection - Getting a reply out of RedisConnection is not trivial - HandleRW... sunt dracones	2019-11-02 14:00:23 +01:00

Michael Friedrich	e31679b2de	Update Redis prefix namespaces and move their declaration into the class ... icinga:config:object:<type>:<sha1> icinga:config:checksum:<type> <sha1> icinga:config:customvar:<type> <sha1> icinga:status:object:<type>:<sha1> This avoids multiple definitions all over the code. Maybe we want to make the schema configurable at some point.	2019-11-02 14:00:23 +01:00

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. refs #4991 fixes #5098 Signed-off-by: Michael Friedrich <michael.friedrich@icinga.com>	2017-03-29 10:17:03 +02:00
