Go Fiber Monitoring

Monitoring

Using the monitoring middleware of Fiber, you can report the server's metrics, inspired by express-status-monitor, which can monitor CPU, memory, request response time, concurrent connection count, and more in real time.

Note: The Monitor is still in the testing phase, and the API may change in the future!

Signature

func New() fiber.Handler

Example

Import the middleware package of the Fiber web framework

import (
  "github.com/gofiber/fiber/v2"
  "github.com/gofiber/fiber/v2/middleware/monitor"
)

After initializing your Fiber application, you can use the following options:

// Initialize with default configuration (assign middleware to /metrics)
app.Get("/metrics", monitor.New())

// Or extend with custom configuration
// Assign middleware to /metrics
// and change the title to "MyService Metrics Page"
app.Get("/metrics", monitor.New(monitor.Config{Title: "MyService Metrics Page"}))

You can also access the API endpoint using curl -X GET -H "Accept: application/json" http://localhost:3000/metrics, which will return:

{"pid":{ "cpu":0.4568381746582226, "ram":20516864,   "conns":3 },
 "os": { "cpu":8.759124087593099,  "ram":3997155328, "conns":44,
    "total_ram":8245489664, "load_avg":0.51 }}
