framework. It provides a set of APIs, libraries, and tools for collecting, exporting, and analyzing telemetry data. Telemetry data includes traces, metrics, and logs. Open Telemetry aims to standardize observability across different systems and programming languages.
complex and distributed systems. Open Telemetry helps in understanding the performance and behavior of web applications. It enables developers to identify and troubleshoot performance bottlenecks. Open Telemetry provides insights into the end-to-end request flow and dependencies between services.
application to capture telemetry data. Open Telemetry provides SDKs and libraries for different programming languages and frameworks. Instrumentation can be done manually or using auto-instrumentation libraries. Auto-instrumentation libraries automatically instrument popular frameworks and libraries.
flow of requests through the application. Metrics provide aggregated data about the performance and behavior of the application. Open Telemetry supports various exporters to send the collected data to backend systems. Exporters can send data to observability platforms like Prometheus, Jaeger, or Elasticsearch.
with popular web frameworks like Express, Django, and Flask. These integrations automatically instrument the framework code to capture telemetry data. Developers can customize the instrumentation and add additional context to the captured data. Integrating Open Telemetry with web frameworks enables detailed monitoring and troubleshooting.
and define the telemetry data you want to capture. Use semantic conventions and standardize attribute names to ensure consistency. Avoid over-instrumentation and focus on capturing relevant data. Regularly review and optimize the instrumentation to minimize performance impact.
demo, we will implement Open Telemetry in a Node.js web application. We will use the Express framework and the Open Telemetry Node.js SDK. The demo will showcase how to capture and export traces and metrics. We will also demonstrate how to integrate Open Telemetry with an observability platform.
