## `lustrestat` collector
|
|
|
|
```json
|
|
"lustrestat": {
|
|
"lctl_command": "/path/to/lctl",
|
|
"exclude_metrics": [
|
|
"setattr",
|
|
"getattr"
|
|
],
|
|
"send_abs_values" : true,
|
|
"send_derived_values" : true,
|
|
"send_diff_values": true,
|
|
"use_sudo": false
|
|
}
|
|
```
|
|
|
|
The `lustrestat` collector uses the `lctl` application with the `get_param` option to get all `llite` metrics (Lustre client). The `llite` metrics are only available for root users. If password-less sudo is configured, you can enable `sudo` in the configuration.
|
|
|
|
Metrics:
|
|
* `lustre_read_bytes` (unit `bytes`)
|
|
* `lustre_read_requests` (unit `requests`)
|
|
* `lustre_write_bytes` (unit `bytes`)
|
|
* `lustre_write_requests` (unit `requests`)
|
|
* `lustre_open`
|
|
* `lustre_close`
|
|
* `lustre_getattr`
|
|
* `lustre_setattr`
|
|
* `lustre_statfs`
|
|
* `lustre_inode_permission`
|
|
* `lustre_read_bw` (if `send_derived_values == true`, unit `bytes/sec`)
|
|
* `lustre_write_bw` (if `send_derived_values == true`, unit `bytes/sec`)
|
|
* `lustre_read_requests_rate` (if `send_derived_values == true`, unit `requests/sec`)
|
|
* `lustre_write_requests_rate` (if `send_derived_values == true`, unit `requests/sec`)
|
|
* `lustre_read_bytes_diff` (if `send_diff_values == true`, unit `bytes`)
|
|
* `lustre_read_requests_diff` (if `send_diff_values == true`, unit `requests`)
|
|
* `lustre_write_bytes_diff` (if `send_diff_values == true`, unit `bytes`)
|
|
* `lustre_write_requests_diff` (if `send_diff_values == true`, unit `requests`)
|
|
* `lustre_open_diff` (if `send_diff_values == true`)
|
|
* `lustre_close_diff` (if `send_diff_values == true`)
|
|
* `lustre_getattr_diff` (if `send_diff_values == true`)
|
|
* `lustre_setattr_diff` (if `send_diff_values == true`)
|
|
* `lustre_statfs_diff` (if `send_diff_values == true`)
|
|
* `lustre_inode_permission_diff` (if `send_diff_values == true`)
