🤗 [Question]: How to log in lowest time unit? #2258
Description
Question Description
When I turn on logging I mostly get, logged, that things took 0s. But I really would like to see how many:
- s
- ms
- μs
- ns
it took.
I come from the Gin framework and am very happy how fiber works, but loggin is a little weird tbh. I would like it to display the ${latency} (how long it took to process the request internally) in the smallest time.unit possible but in the biggest needed.
Code Snippet (optional)
package main
import (
"github.com/gofiber/fiber/v2"
"github.com/gofiber/fiber/v2/middleware/logger"
"github.com/gofiber/template/html"
)
[...]
func main() {
templates := html.New("../templates", ".html")
server := fiber.New(fiber.Config{
CompressedFileSuffix: ".compressed",
UnescapePath: true,
Views: templates,
})
server.Use(logger.New(logger.Config{
Format: "${time} [${ip}] ${status} - ${latency} ${method} ${path}\n",
}))
server.Static("/", "../static", fiber.Static{
Compress: true,
})
server.Get("/", pageMain)
server.Listen(":8003")
}
RESULT:

So I think 0s is really meaningless, as it could be 499ms, 15μs or even 1ns and everything inbetween. I hope there already is a way to configure it, to do what I want and I just missed it in the documentation. If not, kindly see this as a feature request :)
