TL-WPA4220 go package

Go library for the TL-WPA4220

Usage

As a library

package main

import (
    "fmt"

    "github.com/angelbarrera92/tlwpa4220/pkg/tlwpa4220"
)

func main() {
    t := tlwpa4220.Client{
        Username: "admin",
        Password: "hopeItsNotAdmin",
        IP:       "192.168.2.1",
    }

    wireless, err := t.WirelessStatistics()
    if err != nil {
        panic(err)
    }

    for _, device := range wireless.Data {
        fmt.Println(device.Mac)
    }

    err = t.Reboot()
    if err != nil {
        fmt.Println(err)
        panic(err)
    }
}

As a CLI

This package also provides a CLI to interact with the TL-WPA4220. It provides the following commands:

• tlwpa4220 cli: Interact with the TL-WPA4220 using a CLI
• tlwpa4220 serve-metrics: Expose metrics from the TL-WPA4220 in Prometheus format

Build

go build -o tlwpa4220 cmd/main.go
# or
make build

Run commands

The subcommands are:

• wireless-statistics: Get the wireless statistics
• powerline-statistics: Get the powerline statistics
• reboot: Reboot the device

$ ./tlwpa4220 cli --device-ip="192.168.2.1" --password="hopeItsNotAdmin" wireless-statistics
2022/10/21 17:48:42 Running command wireless-statistics

Run the metrics exporter

This package also provides a metrics exporter to expose the wireless statistics as Prometheus metrics.

$ ./tlwpa4220 serve-metrics --device-ip="192.168.2.1" --password="hopeItsNotAdmin"
2022/10/21 17:51:28 Starting the metric recording thread
2022/10/21 17:51:28 Serving metrics on 0.0.0.0:8080/metrics

Metrics

The metrics are:

• connected_devices_total: Number of connected devices
• connected_devices: Number of connected devices per device type
• connected_devices_txpkts: Number of transmitted packets per device
• connected_devices_rxpkts: Number of received packets per device
• powerline_devices_total: Number of powerline devices
• powerline_device: Powerline device information and status
• powerline_device_txpkts: Number of transmitted packets per powerline device
• powerline_device_rxpkts: Number of received packets per powerline device
