Golang Bandwidth monitoring utility for Mikrotik RouterOS Devices

This library reads RouterOS devices (primarily Mikrotik routerboads). Currently only SNMP and the functions to support bandwidth monitoring are supported.

This library is built using gosnmp. However it should be abstracted enough that if one were so inclined you could implement a raw API client.

Currently there only exists the bandwidth tool (See bandwidth.go) which consumes the library and reports interface statistics at a given interval.

go get -u -v github.com/ErebusBat/mikrotik/

# Optional... compile the include tool / sample
go build cmd/*.go

You can download pre-built binaries from the v0.1 Release page.

The tool tries to have intelligent defaults, so if your SNMP community is public and the interface name you want to monitor is the standard ether1 then you just need to specify a host:

$ ./bandwidth -h 192.168.0.1

# Help
$ ./bandwidth --help
Usage of ./bandwidth:
  -c="public": SNMP Community Name
  -h="127.0.0.7": Mikrotik IP
  -i="ether1": Mikrotik Interface Name
  -list=false: Lists all known interfaces and exits
  -s=1s: Sample Interval

If you want to use the library in your own tools then you can do something like

package main

import (
	"log"
	"time"

	"github.com/ErebusBat/mikrotik/snmp"
)

func main() {
	rb := snmp.Connect("10.0.1.250", "public")
	iface, err := rb.FindInterfaceByName("UPSTREAM")
	if err != nil {
		log.Fatalf("ERROR: %v", err)
	}
	sampleChannel := iface.MonitorBandwidth(time.Second * 5)
	for sample := range sampleChannel {
		log.Printf("%s tx/rx %s/%s",
			iface.FullName(),
			sample.TX().BitsString(),
			sample.RX().BitsString(),
		)
	}
}
