OpenTelemetry Standards
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+.
OpenTelemetry Standardsとは
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.
