## `iostat` collector
|
||
|
|
|
||
|
|
```json
|
||
|
|
"iostat": {
|
||
|
|
"exclude_metrics": [
|
||
|
|
"read_ms"
|
||
|
|
],
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
The `iostat` collector reads data from `/proc/diskstats` and outputs a handful **node** metrics. If a metric is not required, it can be excluded from forwarding it to the sink.
