-# Icinga2 Redis <a id="icinga-redis"></a>
-## Subscriptions and events
-
-Using the redis feature allows you to add subscriptions for events which will then be served by Icinga 2 over Redis.
-
-Possible event types:
-
-* CheckResult
-* StateChange
-* Notification
-* AcknowledgementSet
-* AcknowledgementCleared
-* CommentAdded
-* CommentRemoved
-* DowntimeAdded
-* DowntimeRemoved
-* DowntimeStarted
-* DowntimeTriggered
-
-### Creating a subscription
-A subscription is created by creating a new key `icinga:subscription:<name>` in redis with a set of event types. All 
-events matching the the type of those listed will then be added to a list at `icinga:event:<name>`. The events are 
-rotated on a first-in-first-out basis, the default limit is (TODO) and can be overwritten by setting 
-`icinga:subscription:<name>:limit` to the desired ammount.
-
-The events are saved as json encoded strings, similar to the API.
-
-It is recommended to use `LPOP` to read from the list and discard read events at the same time.
-
-Example:
-
-```
-$ redis-cli
-127.0.0.1:6379> SADD icinga:subscription:noma-2 "Notification" "CheckResult"
-(integer) 2
-127.0.0.1:6379> SET icinga:subscription:noma-2:limit 500
-OK
-...
-127.0.0.1:6379> LRANGE icinga:event:noma-2 0 1
-1) "{\"check_result\":{\"active\":true,\"check_source\":\"icinga-1\",\"command\":[\"/usr/lib/nagios/plugins/check_ping\" ... ]}}"
-1) "{\"check_result\":{\"active\":true,\"check_source\":\"icinga-2\",\"command\":[\"/usr/lib/nagios/plugins/check_ping\" ... ]}}"
-```
