iostat collector

iostat collector

  "iostat": {
    "exclude_metrics": [
      "read_ms"
    ],
  }

The iostat collector reads data from /proc/diskstats and outputs a handful node metrics. If a metric is not required, it can be excluded from forwarding it to the sink.

Metrics:

• io_reads
• io_reads_merged
• io_read_sectors
• io_read_ms
• io_writes
• io_writes_merged
• io_writes_sectors
• io_writes_ms
• io_ioops
• io_ioops_ms
• io_ioops_weighted_ms
• io_discards
• io_discards_merged
• io_discards_sectors
• io_discards_ms
• io_flushes
• io_flushes_ms

The device name is added as tag device. For more details, see https://www.kernel.org/doc/html/latest/admin-guide/iostats.html
