# Telegraf Plugin: Redis

### Configuration:

```
# Read Redis's basic status information
[[inputs.redis]]
  ## specify servers via a url matching:
  ##  [protocol://][:password]@address[:port]
  ##  e.g.
  ##    tcp://localhost:6379
  ##    tcp://:password@192.168.99.100
  ##
  ## If no servers are specified, then localhost is used as the host.
  ## If no port is specified, 6379 is used
  servers = ["tcp://localhost:6379"]
```

### Example Output:

Using this configuration:
```
[[inputs.redis]]
  ## specify servers via a url matching:
  ##  [protocol://][:password]@address[:port]
  ##  e.g.
  ##    tcp://localhost:6379
  ##    tcp://:password@192.168.99.100
  ##
  ## If no servers are specified, then localhost is used as the host.
  ## If no port is specified, 6379 is used
  servers = ["tcp://localhost:6379"]
```

When run with:
```
./telegraf -config telegraf.conf -input-filter redis -test
```

It produces:
