Wireless Input Plugin

The wireless plugin gathers metrics about wireless link quality by reading the /proc/net/wireless file. This plugin currently supports linux only.

Configuration:

# Monitor wifi signal strength and quality
[[inputs.wireless]]
  ## Sets 'proc' directory path
  ## If not specified, then default is /proc
  # host_proc = "/proc"

Metrics:

• metric
  • tags:
    • interface (wireless interface)
  • fields:
    • status (int64, gauge) - Its current state. This is a device dependent information
    • link (int64, percentage, gauge) - general quality of the reception
    • level (int64, dBm, gauge) - signal strength at the receiver
    • noise (int64, dBm, gauge) - silence level (no packet) at the receiver
    • nwid (int64, packets, counter) - number of discarded packets due to invalid network id
    • crypt (int64, packets, counter) - number of packet unable to decrypt
    • frag (int64, packets, counter) - fragmented packets
    • retry (int64, packets, counter) - cumulative retry counts
    • misc (int64, packets, counter) - dropped for un-specified reason
    • missed_beacon (int64, packets, counter) - missed beacon packets

Example Output:
