## `nfsiostat` collector
```json
"nfsiostat": {
"exclude_metrics": [
"nfsio_oread"
],
"exclude_filesystems" : [
"/mnt",
],
"use_server_as_stype": false
}
```
The `nfsiostat` collector reads data from `/proc/self/mountstats` and outputs a handful **node** metrics for each NFS filesystem. If a metric or filesystem is not required, it can be excluded from forwarding it to the sink.
Metrics:
* `nfsio_nread`: Bytes transferred by normal `read()` calls
* `nfsio_nwrite`: Bytes transferred by normal `write()` calls
* `nfsio_oread`: Bytes transferred by `read()` calls with `O_DIRECT`
* `nfsio_owrite`: Bytes transferred by `write()` calls with `O_DIRECT`
* `nfsio_pageread`: Pages transferred by `read()` calls
* `nfsio_pagewrite`: Pages transferred by `write()` calls
* `nfsio_nfsread`: Bytes transferred for reading from the server
* `nfsio_nfswrite`: Pages transferred by writing to the server
The `nfsiostat` collector adds the mountpoint to the tags as `stype=filesystem,stype-id=<mountpoint>`. If the server address should be used instead of the mountpoint, use the `use_server_as_stype` config setting.
