lustrestat collector

  "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)

This collector adds an device tag.
