## `lustrestat` collector
```json
"lustrestat": {
"procfiles" : [
"/proc/fs/lustre/llite/lnec-XXXXXX/stats"
],
"exclude_metrics": [
"setattr",
"getattr"
],
"send_abs_values" : true,
"send_derived_values" : true
}
```
The `lustrestat` collector reads from the procfs stat files for Lustre like `/proc/fs/lustre/llite/lnec-XXXXXX/stats`.
Metrics:
* `lustre_read_bytes`
* `lustre_read_requests`
* `lustre_write_bytes`
* `lustre_write_requests`
* `lustre_open`
* `lustre_close`
* `lustre_getattr`
* `lustre_setattr`
* `lustre_statfs`
* `lustre_inode_permission`
* `lustre_read_bytes_bw` (if `send_derived_values == true`)
* `lustre_write_bytes_bw` (if `send_derived_values == true`)
This collector adds an `device` tag.
