# 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 <!-- @/docs/includes/plugin_config.md -->

In addition to the plugin-specific configuration settings, plugins support
additional global and plugin configuration settings. These settings are used to
modify metrics, tags, and field or create aliases and configure ordering, etc.
See the [CONFIGURATION.md](/telegraf/v1/configuration/#plugins) for more details.

[CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins

## Configuration

```toml @sample.conf
# 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
