How can I use hooks in Logrus for logging?

You can use hooks in Logrus to add custom behavior to your logging. Hooks allow you to execute code when a log event is fired.

Can you give me an example of a hook implementation?

Sure! Here's a simple example:

package main

import (
	"github.com/sirupsen/logrus"
)

type MyHook struct {}

func (h *MyHook) Levels() []logrus.Level {
	return logrus.AllLevels
}

func (h *MyHook) Fire(entry *logrus.Entry) error {
	// Custom logic here
	return nil
}

func main() {
	log := logrus.New()
	log.AddHook(&MyHook{})
	log.Info("This is a log message")
}

What are some common use cases for hooks?

Common use cases include sending logs to external services, modifying log entries, or triggering alerts based on log levels.

Are there any built-in hooks in Logrus?

Yes, Logrus has built-in hooks for sending logs to various services like Loggly, Papertrail, and more. You can also create your own.
