diskstat collector

  "diskstat": {
    "exclude_metrics": [
      "part_max_used"
    ],
    "only_metrics": [
      "disk_free",
    ],
    "exclude_mounts": [
      "slurm-tmpfs"
    ]
  }

The diskstat collector reads data from /proc/self/mounts and outputs a handful node metrics. Any mount point containing one of the strings specified in exclude_mounts will be skipped during metric collection.

Both filtering mechanisms are supported:

• exclude_metrics: Excludes the specified metrics.
• only_metrics: If provided, only the listed metrics are collected. This takes precedence over exclude_metrics.

Metrics per device (with device tag):

• disk_total (unit GBytes)
• disk_free (unit GBytes)

Global metrics:

• part_max_used (unit percent)
