# 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](/telegraf/v1/configuration/#plugins) for more details.

## Configuration

```toml
# 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

## Example Output

This section shows example output in Line Protocol format.

```text
wireless,host=example.localdomain,interface=wlan0 misc=0i,frag=0i,link=60i,level=-50i,noise=-256i,nwid=0i,crypt=0i,retry=1525i,missed_beacon=0i,status=0i 1519843022000000000
