description OpenTelemetry Overview
OpenTelemetry is an open-source observability framework that provides standardized APIs and SDKs for collecting telemetry data – metrics, logs, and traces – from applications and infrastructure, enabling comprehensive monitoring and troubleshooting across diverse environments.
help OpenTelemetry FAQ
What is the difference between OpenTelemetry and OpenTracing?
OpenTelemetry is the successor project formed by the merger of OpenTracing and OpenCensus, combining their strengths into a single standard. It provides a unified way to collect metrics, logs, and traces, eliminating the need to use separate libraries for distributed tracing.
Do I still need Jaeger or Zipkin if I use OpenTelemetry in my application?
Yes, because OpenTelemetry is just the instrumentation layer, the APIs and SDKs used to generate the telemetry data. You will still need to export the collected traces to a backend like Jaeger, Zipkin, or Datadog for storage and visualization.
Which programming languages are officially supported by OpenTelemetry?
OpenTelemetry provides official APIs, SDKs, and semantic conventions for major programming languages including Java, Python, Go, JavaScript, C++, and Rust. These libraries allow developers to automatically or manually instrument their applications to capture telemetry data.
How does OpenTelemetry handle logs, metrics, and traces together?
OpenTelemetry uses the OpenTelemetry Protocol (OTLP) to standardize the export of all three signals: logs, metrics, and traces. This unified approach allows you to send all telemetry data from your application to a single collector, making it easier to correlate performance metrics with specific user request traces.
