Redis monitoring with Netdata

Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker.

This module monitors one or more Redis instances, depending on your configuration.

It collects information and statistics about the server executing the following commands:


  • Accepted and rejected (maxclients limit) connections in connections/s
  • Clients in clients
  • Memory usage in bytes
  • Ratio between used_memory_rss and used_memory in ratio
  • Bandwidth in kilobits/s
  • Connected replicas in replicas
  • Operations that produced changes since the last SAVE or BGSAVE in operations
  • Duration of the on-going RDB save operation if any in seconds
  • Status of the last RDB save operation in status
  • Processed commands in queries/s
  • Calls per command in calls/s
  • Total CPU time consumed by the commands in usec
  • Average CPU consumed per command execution in usec/s
  • Keys lookup hit rate in percentage
  • Evicted keys due to maxmemory limit in keys/s
  • Expired keys in keys/s
  • Keys per database in keys
  • Keys with an expiration per database in keys
  • Uptime in seconds


Edit the go.d/redis.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata # Replace this path with your Netdata config directory
sudo ./edit-config go.d/redis.conf

There are two connection types: by tcp socket and by unix socket.

# by tcp socket
# by unix socket

Needs only address, here is an example with two jobs:

- name: local
address: 'redis://@'
- name: remote
address: 'redis://user:[email protected]:6379'

For all available options, see the redis collector's configuration file.


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.

First, navigate to your plugins directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the setting plugins directory. Once you're in the plugin's directory, switch to the netdata user.

cd /usr/libexec/netdata/plugins.d/
sudo -u netdata -s

You can now run the go.d.plugin to debug the collector:

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