## `nfs4stat` collector

```json
  "nfs4stat": {
    "nfsstat" : "/path/to/nfsstat",
    "exclude_metrics": [
      "nfs4_total"
    ]
  }
```

The `nfs4stat` collector reads data from `nfsstat` command and outputs a handful **node** metrics. If a metric is not required, it can be excluded from forwarding it to the sink. There is currently no possibility to get the metrics per mount point.


Metrics:
* `nfs4_total` 
* `nfs4_null` 
* `nfs4_read` 
* `nfs4_write` 
* `nfs4_commit` 
* `nfs4_open`
