OpenTelemetry

Adopt vendor-neutral telemetry with consistent instrumentation across services.

Prerequisites

• Application services running in containers or on VMs
• Backend for traces (Jaeger, Tempo, Datadog, or any OTLP receiver)
• Backend for metrics (Prometheus, Mimir, or OTLP receiver)
• Kubernetes cluster (for collector deployment) or VM with systemd
• Network access from services to collector, and collector to backends

Core Workflow

1. Define semantic conventions for services, environments, and versions.
2. Add SDK or auto-instrumentation in each service.
3. Run an OpenTelemetry Collector to receive, transform, and export telemetry.
4. Validate cardinality and sampling to control cost.
5. Create golden signals dashboards and alerting from collected data.
