lustrestat collector

  "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.
