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
