I korthet

OpenTelemetry is an open standard for collecting observability data (traces, metrics, logs) from applications and infrastructure. Language SDKs (Python, Go, Java, Node.js) auto-instrument code. Data exported to any backend (Datadog, New Relic, Elastic). Learning curve: 2-3 weeks for basic instrumentation, 6-8 weeks for production optimization. Reduces vendor lock-in, standardizes observability. Teams using OpenTelemetry report 40% faster incident detection, 20% reduction in MTTR. Salary: senior observability engineers earn $160k-240k+.

Vad är OpenTelemetry Standards

OpenTelemetry (OTEL) is a vendor-neutral standard for collecting observability data (traces, metrics, logs) from applications. Language SDKs auto-instrument popular libraries (HTTP, databases, caches). Data is exported to any backend (Jaeger, Datadog, New Relic, etc) via OTEL protocol. Benefit: applications instrumented once, data sent to multiple backends, swappable without code changes.

❓ Vanliga frågor

What's the difference between OpenTelemetry and Datadog/New Relic?
OTEL = open standard for collecting data. Datadog/New Relic = vendors selling analysis tools. OTEL works with any backend. Move from Datadog to New Relic = change exporter (2 lines code), keep instrumentation. No vendor lock-in.
Do I need to instrument every line of code?
No. OTEL auto-instruments popular libraries (Django, FastAPI, Spring, etc). Manual instrumentation for custom code. 80% coverage = 20% effort.
How much overhead does OTEL add?
Tracing = <5% CPU overhead (if sampled). Metrics = <1% overhead. Logging = depends on volume. Typical: negligible impact.
Can I sample traces to reduce cost?
Yes, highly recommended. Sample 1% of requests in production (99% do nothing, 1% traced in detail). 100x cost reduction.
What happens if the OTEL collector is down?
Graceful degradation. App continues, telemetry data queued locally, sent once collector is back. No data loss (up to queue limit).
