Do you use error grouping systems for application monitoring?

Yes, specialized systems such as Sentry, Rollbar, Bugsnag, and others are often used for monitoring and grouping errors in Go applications. They allow automatic collection, aggregation, and analysis of errors, which facilitates their quick detection and correction.

Example of integrating Sentry into a Go application:

import (
    "github.com/getsentry/sentry-go"
    "log"
)

func main() {
    err := sentry.Init(sentry.ClientOptions{
        Dsn: "https://examplePublicKey@o0.ingest.sentry.io/0",
    })
    if err != nil {
        log.Fatalf("sentry.Init: %s", err)
    }

    defer sentry.Flush(2 * time.Second)

    // Example of sending an error
    sentry.CaptureMessage("Something went wrong")
}

Using such systems helps to centrally track errors, see their frequency and context, which significantly improves the quality of support and development of the application.
