Redis module
editRedis module
editThis module periodically fetches metrics from Redis servers.
The defaut metricsets are info
and keyspace
.
Module-specific configuration notes
editThe Redis module has these additional config options:
-
hosts
- URLs that are used to connect to Redis. URL format: redis://[:password@]host[:port][/db-number][?option=value] redis://HOST[:PORT][?password=PASSWORD[&db=DATABASE]]
-
password
- The password to authenticate, by default it’s empty.
-
idle_timeout
-
The duration to remain idle before closing connections. If
the value is zero, then idle connections are not closed. The default value
is 2 times the module period to allow a connection to be reused across
fetches. The
idle_timeout
should be set to less than the server’s connection timeout. -
network
-
The network type to be used for the Redis connection. The default value is
tcp
. -
maxconn
- The maximum number of concurrent connections to Redis. The default value is 10.
Compatibility
editThe redis metricsets info
, key
and keyspace
are compatible with all distributions of Redis (OSS and enterprise).
They were tested with Redis 3.2.12, 4.0.11, 5.0-rc4 and 6.2.6, and are expected to work with all versions >= 3.0.
Example configuration
editThe Redis module supports the standard configuration options that are described in Modules. Here is an example configuration:
metricbeat.modules: - module: redis metricsets: ["info", "keyspace"] enabled: true period: 10s # Redis hosts hosts: ["127.0.0.1:6379"] # Timeout after which time a metricset should return an error # Timeout is by default defined as period, as a fetch of a metricset # should never take longer then period, as otherwise calls can pile up. #timeout: 1s # Optional fields to be added to each event #fields: # datacenter: west # Network type to be used for redis connection. Default: tcp #network: tcp # Max number of concurrent connections. Default: 10 #maxconn: 10 # Filters can be used to reduce the number of fields sent. #processors: # - include_fields: # fields: ["beat", "metricset", "redis.info.stats"] # Redis AUTH password. Empty by default. #password: foobared
Metricsets
