# 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.nginx]]
## 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:
