A single distribution of libraries that automatically collects traces and metrics from your app, displays them locally, and sends them to any analysis tool.

The key features of OpenCensus include:

• Standard wire protocols and consistent APIs for handling trace and metric data.
• A single set of libraries for many languages, including Java, C++, Go, .Net, Python, PHP, Node.js, Erlang, and Ruby.
• Included integrations with web and RPC frameworks, making traces and metrics available out of the box.
• Included exporters for storage and analysis tools. Right now the list includes Zipkin, Prometheus, Datadog, Stackdriver, and Azure App Insights.
• Full open source availability for additional integrations and export options.
• No additional server or daemon is required to support OpenCensus.
• In process debugging: an optional agent for displaying request and metrics data on instrumented hosts.
