Wireless Input Plugin

This plugin gathers metrics about wireless link quality by reading the /proc/net/wireless file.

Introduced in: Telegraf v1.9.0 Tags: network OS support: linux

Global configuration options

Plugins support additional global and plugin configuration settings for tasks such as modifying metrics, tags, and fields, creating aliases, and configuring plugin ordering. See CONFIGURATION.md for more details.

Configuration

# Monitor wifi signal strength and quality
# This plugin ONLY supports Linux
[[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
