Kas saaksite selgitada, mis on OpenTelemetry ja milleks see on metrikate ja jälgimiste kogumisel ja analüüsil?

OpenTelemetry is an open standard and a set of tools for collecting, processing, and exporting telemetry data such as metrics, traces, and logs from distributed systems.

The main tasks of OpenTelemetry:

• Collection of metrics and traces: allows monitoring the performance and behavior of applications.
• Unified data format: standardizes data for easy analysis and integration with various monitoring systems.
• Support for distributed traces: helps understand the path of a request through multiple services.

Example of usage in Java:

// Initialization of OpenTelemetry SDK
OpenTelemetry openTelemetry = OpenTelemetrySdk.builder()
    .setTracerProvider(SdkTracerProvider.builder().build())
    .build();

Tracer tracer = openTelemetry.getTracer("exampleTracer");

Span span = tracer.spanBuilder("exampleOperation").startSpan();
try {
    // operation code
} finally {
    span.end();
}

Thus, OpenTelemetry helps developers obtain detailed information about application operation, improving their reliability and performance.
