Slog-Sentry

Sentry hook for the standard Golang logger slog.

A minimalist hook for the standard Golang logger slog, which enables sending our logs to the Sentry.

Upon hook initialization, you need to provide it with a standard log handler (TextHandler, JSONHandler, etc.), as well as the log levels you want to send to Sentry.

Messages of the Error level expect the original error as one of the following arguments: err or error.

Example

package main

import (
	"io"
	"log/slog"
	"os"
	"time"

	"github.com/getsentry/sentry-go"
	"github.com/ihippik/slog-sentry"
)

func main() {
	if err := sentry.Init(sentry.ClientOptions{
		Dsn: "myDSN",
	}); err != nil {
		slog.Error("init sentry", "err", err)
	}

	defer sentry.Flush(time.Second * 2)

	opt := slog.HandlerOptions{
		Level: slog.LevelDebug,
	}

	handler := slog.NewTextHandler(os.Stdout, &opt)
	hook := slogsentry.NewSentryHandler(handler, []slog.Level{slog.LevelWarn, slog.LevelError})

	logger := slog.New(hook)
	logger.Info("info message")
	logger.Warn("warn message")
	logger.Error("error message", "err", io.ErrNoProgress)
}
