Redis module

edit

This module periodically fetches metrics from Redis servers.

The defaut metricsets are info and keyspace.

Module-specific configuration notes

edit

The 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

edit

The 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 and 5.0-rc4, and are expected to work with all versions >= 3.0.

Example configuration

edit

The 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
