🌟 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
• Horizontally scalable
• Efficient compression, low disk space requirements
• Can handle high-cardinality tags/labels
• Calculate the performance "diff" between various tags/labels and time periods
• Advanced analysis UI

💻 Quick Start: Run Pyroscope Locally

Homebrew

brew install pyroscope-io/brew/pyroscope
brew services start pyroscope

Docker

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