## `nfsiostat` collector
|
|
|
|
```json
|
|
"nfsiostat": {
|
|
"exclude_metrics": [
|
|
"oread", "pageread"
|
|
],
|
|
"exclude_filesystems": [
|
|
"/mnt"
|
|
],
|
|
"use_server_as_stype": false,
|
|
"send_abs_values": false,
|
|
"send_derived_values": true
|
|
}
|
|
```
|
|
|
|
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. **Note:** When excluding metrics, you must provide the base metric name (e.g. pageread) without the nfsio_ prefix. This exclusion applies to both absolute and derived values.
|
|
|
|
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
|
|
|
|
For each of these, if derived values are enabled, an additional metric is sent with the `_bw` suffix, which represents the rate:
|
|
|
|
* For normal byte metrics: `unit=bytes/sec`
|
|
* For page metrics: `unit=4K_pages/s`
|
|
|
|
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.
