netstat collector

  "netstat": {
    "include_devices": [
      "eth0",
      "eno1"
    ],
    "send_abs_values": true,
    "send_derived_values": true,
    "interface_aliases": {
      "eno1": ["eno1np0", "eno1_alt"],
      "eth0": ["eth0_alias"]
    }
  }

The netstat collector reads data from /proc/net/dev and outputs a handful node metrics. With the include_devices list you can specify which network devices should be measured. Note: Most other collectors use an exclude list instead of an include list. Optionally, you can define an interface_aliases mapping. For each canonical device (as listed in include_devices), you may provide an array of aliases that may be reported by the system. When an alias is detected, it is preferred for matching, while the output tag stype-id always shows the actual system-reported name.

Metrics:

  • net_bytes_in (unit=bytes)
  • net_bytes_out (unit=bytes)
  • net_pkts_in (unit=packets)
  • net_pkts_out (unit=packets)
  • net_bytes_in_bw (unit=bytes/sec if send_derived_values == true)
  • net_bytes_out_bw (unit=bytes/sec if send_derived_values == true)
  • net_pkts_in_bw (unit=packets/sec if send_derived_values == true)
  • net_pkts_out_bw (unit=packets/sec if send_derived_values == true)

The device name is added as tag stype=network,stype-id=<device>.
