On 2023-03-15, Grafana Labs acquired Pyroscope.

The teams and codebases of both Grafana Phlare and Pyroscope have merged into Grafana Pyroscope.

What is Grafana Pyroscope?

Grafana Pyroscope is an open source continuous profiling platform. It will help you:

• Find performance issues and bottlenecks in your code
• Use high-cardinality tags/labels to analyze your application
• Resolve issues with high CPU utilization
• Track down memory leaks
• Understand the call tree of your application
• Auto-instrument your code to link profiling data to traces

🔥 Pyroscope Live Demo 🔥

Features

• Minimal CPU overhead
• Efficient compression, low disk space requirements
• Can handle high-cardinality tags/labels
• Calculate the performance "diff" between various tags/labels and time periods
• Can store years of profiling data from multiple applications
• Advanced analysis UI

Run Pyroscope Locally

docker run -it -p 4040:4040 grafana/pyroscope

For more documentation on how to configure Pyroscope server, see our server documentation.

Send data to server via Pyroscope agent (language specific)
