Rääkige mulle telemeetria kohta.

Telemetry is the collection, transmission, and analysis of data about the operation of software or hardware in real time. In the context of Golang, telemetry helps monitor performance, detect errors, and understand system behavior.

An example of using telemetry in Go is integration with OpenTelemetry for collecting metrics and traces:

import (
    "go.opentelemetry.io/otel"
    "go.opentelemetry.io/otel/trace"
)

func main() {
    tracer := otel.Tracer("example-tracer")
    ctx, span := tracer.Start(context.Background(), "operation")
    defer span.End()
    // perform operation
}

Telemetry helps respond quickly to issues, optimize performance, and improve product quality.
