Redis module

Prefer to use Elastic Agent for this use case?

Refer to the Elastic Integrations documentation.

Learn more

Elastic Agent is a single, unified way to add monitoring for logs, metrics, and other types of data to a host. It can also protect hosts from security threats, query data from operating systems, forward data from remote services or hardware, and more. Refer to the documentation for a detailed comparison of Beats and Elastic Agent.

This module periodically fetches metrics from Redis servers.

The defaut metricsets are info and keyspace.

Module-specific configuration notes

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

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, 5.0-rc4 and 6.2.6, and are expected to work with all versions >= 3.0.

Example configuration

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 username (Redis 6.0+). Empty by default.
  #username: user

  # Redis AUTH password. Empty by default.
  #password: pass

  # Optional SSL/TLS (Redis 6.0+). By default is false.
  #ssl.enabled: true

  # List of root certificates for SSL/TLS server verification
  #ssl.certificate_authorities: ["/etc/pki/root/ca.crt"]

  # Certificate for SSL/TLS client authentication
  #ssl.certificate: "/etc/pki/client/cert.crt"

  # Client certificate key file
  #ssl.key: "/etc/pki/client/cert.key"
