GoDoc: https://pkg.go.dev/github.com/samber/slog-sentry/v2

Handler options

type Option struct {
    // log level (default: debug)
    Level     slog.Leveler
    // sentry hub (default: current hub)
    Hub       *sentry.Hub

    // optional: customize Sentry event builder
    Converter Converter

    // optional: see slog.HandlerOptions
    AddSource   bool
    ReplaceAttr func(groups []string, a slog.Attr) slog.Attr
}

slogsentry.SourceKey = "source"
slogsentry.ContextKey = "extra"
slogsentry.ErrorKeys = []string{"error", "err"}
slogsentry.LogLevels = map[slog.Level]sentry.Level{...}

Supported attributes

The following attributes are interpreted by slogsentry.DefaultConverter:

Other attributes will be injected in context Sentry field.

Users and tags must be of type slog.Group. Eg:

slog.Group("user",
    slog.String("id", "user-123"),
    slog.String("username", "samber"),
    slog.Time("created_at", time.Now()),
)

The Sentry agent is responsible for collecting modules.

Example

import (
    "github.com/getsentry/sentry-go"
    slogsentry "github.com/samber/slog-sentry/v2"
    "log/slog"
)

func main() {
    err := sentry.Init(sentry.ClientOptions{
        Dsn:           myDSN,
        EnableTracing: false,
    })
    if err != nil {
        log.Fatal(err)
    }

    defer sentry.Flush(2 * time.Second)

    logger := slog.New(slogsentry.Option{Level: slog.LevelDebug}.NewSentryHandler())
    logger = logger.
        With("environment", "dev").
        With("release", "v1.0.0")

    // log error
    logger.
        With("category", "sql").
        With("query.statement", "SELECT COUNT(*) FROM users;").
        With("query.duration", 1*time.Second).
        With("error", fmt.Errorf("could not count users")).
        Error("caramba!")

    // log user request
    logger.
        With(
            slog.Group("user",
                slog.String("id", "user-123"),
                slog.Time("created_at", time.Now()),
            ),
        ).
        With("request", httpRequest)
        With("status", 200).
        Info("received http request")
}
