Beego project with prometheus monitor.

Install && import

• Create a project with bee tool.

bee new bgprom 

• Add promhttp

package main

import (
	_ "github.com/chenyangguang/bgprom/routers"
	"github.com/astaxie/beego"
    "github.com/prometheus/client_golang/prometheus/promhttp"
)

func main() {
    beego.Handler("/metrics", promhttp.Handler())
	beego.Run()
}

to the main.go.

Run

bee run 

Access http://localhost:8080/metrics in browser.

Add Counter for test

New a controller and import "github.com/prometheus/client_golang/prometheus" .

the test controller should look like this:

var (
	codeCounter = prometheus.NewCounter(
		prometheus.CounterOpts{
			Name: "http_request_total_code",
			Help: "total request code controller",
		},
	)
)
type CodeController struct {
	beego.Controller
}
func init() {
	prometheus.MustRegister(codeCounter)
}
func (c *CodeController) Get() {
	codeCounter.Inc()
	c.TplName = "code.tpl"
}

• Visit browser by http://localhost:8080/metrics if there comes the result like below:

...
# HELP http_request_total_code total request code controller
# TYPE http_request_total_code counter
http_request_total_code 0
...

it means works!

• Access http://localhost:8080/code, it will turn out that http_request_total_code is increasing. Go to "http://localhost:8080/metrics" again. Emm.... It works well:

...
# HELP http_request_total_code total request code controller
# TYPE http_request_total_code counter
http_request_total_code 1
...

Well done! Other types are similar(like Summary, Gauge, Histogram, SummaryVec and so on).

todo

• Add base prometheus metric
