editredis
editThis output will send events to a Redis queue using RPUSH. The RPUSH command is supported in Redis v0.0.7+. Using PUBLISH to a channel requires at least v1.3.8+. While you may be able to make these Redis versions work, the best performance and stability will be found in more recent stable versions. Versions 2.6.0+ are recommended.

Details
edit
batch
edit- Value type is boolean
-
Default value is
false
Set to true if you want Redis to batch up values and send 1 RPUSH command
instead of one command per value to push on the list. Note that this only
works with data_type="list"
mode right now.
If true, we send an RPUSH every "batch_events" events or
"batch_timeout" seconds (whichever comes first).
Only supported for data_type
is "list".
batch_events
edit- Value type is number
-
Default value is
50
If batch is set to true, the number of events we queue up for an RPUSH.
batch_timeout
edit- Value type is number
-
Default value is
5
If batch is set to true, the maximum amount of time between RPUSH commands when there are pending events to flush.
codec
edit- Value type is codec
-
Default value is
"plain"
The codec used for output data. Output codecs are a convenient method for encoding your data before it leaves the output, without needing a separate filter in your Logstash pipeline.
congestion_interval
edit- Value type is number
-
Default value is
1
How often to check for congestion. Default is one second. Zero means to check on every event.
congestion_threshold
edit- Value type is number
-
Default value is
0
In case Redis data_type
is list
and has more than @congestion_threshold
items,
block until someone consumes them and reduces congestion, otherwise if there are
no consumers Redis will run out of memory, unless it was configured with OOM protection.
But even with OOM protection, a single Redis list can block all other users of Redis,
until Redis CPU consumption reaches the max allowed RAM size.
A default value of 0 means that this limit is disabled.
Only supported for list
Redis data_type
.
data_type
edit-
Value can be any of:
list
,channel
- There is no default value for this setting.
Either list or channel. If redis_type
is list, then we will set
RPUSH to key. If redis_type
is channel, then we will PUBLISH to key
.
