# 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.
|
||
|
|
|
||
|
|
## 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][CONFIGURATION.md] for more details.

|
## 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
|
||
|
|

|
||
|
|
- 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
|
||
