ibstat collector

  "ibstat": {
    "exclude_devices": [
      "mlx4"
    ],
    "send_abs_values": true,
    "send_derived_values": true
  }

The ibstat collector includes all Infiniband devices that can be found below /sys/class/infiniband/ and where any of the ports provides a LID file (/sys/class/infiniband/<dev>/ports/<port>/lid)

The devices can be filtered with the exclude_devices option in the configuration.

For each found LID the collector reads data through the sysfs files below /sys/class/infiniband/<device>. (See: https://www.kernel.org/doc/Documentation/ABI/stable/sysfs-class-infiniband)

Metrics:

• ib_recv
• ib_xmit
• ib_recv_pkts
• ib_xmit_pkts
• ib_total = ib_recv + ib_xmit (if send_total_values == true)
• ib_total_pkts = ib_recv_pkts + ib_xmit_pkts (if send_total_values == true)
• ib_recv_bw (if send_derived_values == true)
• ib_xmit_bw (if send_derived_values == true)
• ib_recv_pkts_bw (if send_derived_values == true)
• ib_xmit_pkts_bw (if send_derived_values == true)

The collector adds a device tag to all metrics
