Pprof

Pprof middleware for Fiber that serves via its HTTP server runtime profiling data in the format expected by the pprof visualization tool. The package is typically only imported for the side effect of registering its HTTP handlers. The handled paths all begin with /debug/pprof/.

Signatures

func New() fiber.Handler

Examples

Import the middleware package that is part of the Fiber web framework

import (
    "github.com/gofiber/fiber/v3"
    "github.com/gofiber/fiber/v3/middleware/pprof"
)

After you initiate your Fiber app, you can use the following possibilities:

// Initialize default config
app.Use(pprof.New())

// Or extend your config for customization

// For example, in systems where you have multiple ingress endpoints, it is common to add a URL prefix, like so:
app.Use(pprof.New(pprof.Config{Prefix: "/endpoint-prefix"}))

// This prefix will be added to the default path of "/debug/pprof/", for a resulting URL of: "/endpoint-prefix/debug/pprof/".
