github.com/gofiber/fiber/v2@v2.47.0/docs/api/middleware/pprof.md (about) 1 --- 2 id: pprof 3 title: Pprof 4 --- 5 6 Pprof middleware for [Fiber](https://github.com/gofiber/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/. 7 8 ## Signatures 9 10 ```go 11 func New() fiber.Handler 12 ``` 13 14 ## Examples 15 16 Import the middleware package that is part of the Fiber web framework 17 18 ```go 19 import ( 20 "github.com/gofiber/fiber/v2" 21 "github.com/gofiber/fiber/v2/middleware/pprof" 22 ) 23 ``` 24 25 After you initiate your Fiber app, you can use the following possibilities: 26 27 ```go 28 // Initialize default config 29 app.Use(pprof.New()) 30 31 // Or extend your config for customization 32 33 // For example, in systems where you have multiple ingress endpoints, it is common to add a URL prefix, like so: 34 app.Use(pprof.New(pprof.Config{Prefix: "/endpoint-prefix"})) 35 36 // This prefix will be added to the default path of "/debug/pprof/", for a resulting URL of: "/endpoint-prefix/debug/pprof/". 37 ``` 38 39 ## Config 40 41 ```go 42 // Config defines the config for middleware. 43 type Config struct { 44 // Next defines a function to skip this middleware when returned true. 45 // 46 // Optional. Default: nil 47 Next func(c *fiber.Ctx) bool 48 49 // Prefix defines a URL prefix added before "/debug/pprof". 50 // Note that it should start with (but not end with) a slash. 51 // Example: "/federated-fiber" 52 // 53 // Optional. Default: "" 54 Prefix string 55 } 56 ``` 57 58 ## Default Config 59 60 ```go 61 var ConfigDefault = Config{ 62 Next: nil, 63 } 64 ```
