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:

INFO ALL

Metrics

All metrics have "redis." prefix.

Configuration

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.

Note: If the Redis server is password protected via the requirepass option, make sure you have a colon before the password.

# by tcp socket
redis://<user>:<password>@<host>:<port>

# by unix socket
unix://<user>:<password>@</path/to/redis.sock

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

jobs:
  - name: local
    address: 'redis://@127.0.0.1:6379'

  - name: local
    address: 'redis://:password@127.0.0.1:6379'

  - name: remote
    address: 'redis://user:password@203.0.113.0:6379'

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

Troubleshooting

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
```
