# This plugin does NOT support FreeBSD
[[inputs.nats]]
  ## The address of the monitoring endpoint of the NATS server
  server = "http://localhost:8222"

  ## Maximum time to receive response
  # response_timeout = "5s"
```

## Metrics

-   nats
    -   tags
        -   server
    -   fields:
        -   uptime (integer, nanoseconds)
        -   mem (integer, bytes)
        -   subscriptions (integer, count)
        -   out\_bytes (integer, bytes)
        -   connections (integer, count)
        -   in\_msgs (integer, bytes)
        -   total\_connections (integer, count)
        -   cores (integer, count)
        -   cpu (integer, count)
        -   slow\_consumers (integer, count)
        -   routes (integer, count)
        -   remotes (integer, count)
        -   out\_msgs (integer, count)
        -   in\_bytes (integer, bytes)

## Example Output

```text
nats,server=http://localhost:8222 uptime=117158348682i,mem=6647808i,subscriptions=0i,out_bytes=0i,connections=0i,in_msgs=0i,total_connections=0i,cores=2i,cpu=0,slow_consumers=0i,routes=0i,remotes=0i,out_msgs=0i,in_bytes=0i 1517015107000000000
