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>.

Metrics:

  • ib_recv
  • ib_xmit
  • ib_recv_pkts
  • ib_xmit_pkts
  • 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
