Plugin: go.d.plugin Module: redis


This collector monitors the health and performance of Redis servers and collects general statistics, CPU and memory consumption, replication information, command statistics, and more.

It connects to the Redis instance via a TCP or UNIX socket and executes the following commands:

This collector is supported on all platforms.

This collector supports collecting metrics from multiple instances of this integration, including remote instances.

Default Behavior


By default, it detects instances running on localhost by attempting to connect using known Redis TCP and UNIX sockets:

  • /tmp/redis.sock
  • /var/run/redis/redis.sock
  • /var/lib/redis/redis.sock


The default configuration for this integration does not impose any limits on data collection.

Performance Impact

The default configuration for this integration is not expected to impose a significant performance impact on the system.



No action required.



The configuration file name for this integration is go.d/redis.conf.

You can edit the configuration file using the edit-config script from the Netdata config directory.

cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/redis.conf


The following options can be defined globally: update_every, autodetection_retry.

Name Description Default Required
update_every Data collection frequency. 5 False
autodetection_retry Recheck interval in seconds. Zero means no recheck will be scheduled. 0 False
address Redis server address. redis://@localhost:6379 True
timeout Dial (establishing new connections), read (socket reads) and write (socket writes) timeout in seconds. 1 False
username Username used for authentication. False
password Password used for authentication. False
tls_skip_verify Server certificate chain and hostname validation policy. Controls whether the client performs this check. False False
tls_ca Certificate authority that client use when verifying server certificates. False
tls_cert Client tls certificate. False
tls_key Client tls key. False


TCP socket

An example configuration.

  - name: local
    address: 'redis://@'

Unix socket

An example configuration.

  - name: local
    address: 'unix://@/tmp/redis.sock'

TCP socket with password

An example configuration.

  - name: local
    address: 'redis://:password@'


Note: When you define multiple jobs, their names must be unique.

Local and remote instances.

  - name: local
    address: 'redis://:password@'

  - name: remote
    address: 'redis://user:password@'


Metrics grouped by scope.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.

Per Redis instance

These metrics refer to the entire monitored application.

This scope has no labels.


Metric Dimensions Unit
redis.connections accepted, rejected connections/s
redis.clients connected, blocked, tracking, in_timeout_table clients
redis.ping_latency min, max, avg seconds
redis.commands processes commands/s
redis.keyspace_lookup_hit_rate lookup_hit_rate percentage
redis.memory max, used, rss, peak, dataset, lua, scripts bytes
redis.mem_fragmentation_ratio mem_fragmentation ratio
redis.key_eviction_events evicted keys/s received, sent kilobits/s
redis.rdb_changes changes operations
redis.bgsave_now current_bgsave_time seconds
redis.bgsave_health last_bgsave status
redis.bgsave_last_rdb_save_since_time last_bgsave_time seconds
redis.aof_file_size current, base bytes
redis.commands_calls a dimension per command calls
redis.commands_usec a dimension per command microseconds
redis.commands_usec_per_sec a dimension per command microseconds/s
redis.key_expiration_events expired keys/s
redis.database_keys a dimension per database keys
redis.database_expires_keys a dimension per database keys
redis.connected_replicas connected replicas
redis.master_link_status up, down status
redis.master_last_io_since_time time seconds
redis.master_link_down_since_time time seconds
redis.uptime uptime seconds


The following alerts are available:

Alert name On metric Description
redis_connections_rejected redis.connections connections rejected because of maxclients limit in the last minute
redis_bgsave_slow redis.bgsave_now duration of the on-going RDB save operation
redis_bgsave_broken redis.bgsave_health status of the last RDB save operation (0: ok, 1: error)
redis_master_link_down redis.master_link_down_since_time time elapsed since the link between master and slave is down


Debug Mode

To troubleshoot issues with the redis collector, run the go.d.plugin with the debug option enabled. The output should give you clues as to why the collector isn’t working.

  • Navigate to the plugins.d directory, usually at /usr/libexec/netdata/plugins.d/. If that’s not the case on your system, open netdata.conf and look for the plugins setting under [directories].

    cd /usr/libexec/netdata/plugins.d/
  • Switch to the netdata user.

    sudo -u netdata -s
  • Run the go.d.plugin to debug the collector:

    ./go.d.plugin -d -m redis
