OpenTelemetry, the open standard for observability
A CNCF project backed by every major vendor, OpenTelemetry defines a single way to instrument, collect and export traces, metrics and logs. It has become the common foundation of modern observability.

What it brings to observability
- One standard for every signalTraces, metrics and logs share the same model, attributes and context: jump from an alert to the trace and then to the log in one click.
- No vendor lock-inInstrument once and send to Prometheus, Grafana, Jaeger, Elastic, Datadog or Dynatrace by changing configuration, not code.
- A telemetry pipeline you controlThe Collector filters, enriches, masks sensitive data and routes telemetry: less noise, lower costs.
- Fast instrumentationAutomatic agents and SDKs for Java, Python, Go, .NET, Node.js… with semantic conventions shared by every service.
Why start with this course
- It is the foundation of modern observability: traces, metrics and logs then share the same vocabulary across all our courses.
- It is the second most active CNCF project after Kubernetes: vendors and clouds adopt it as their ingestion format.
- SREs, DevOps engineers and developers are expected to know it: instrumenting and running a Collector pays off with every tool.
- It underpins our Alloy, Tempo, Jaeger, Bindplane and Datadog courses: you will progress through them faster.
