What is Pyroscope?

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

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

Add Pyroscope Server locally in 2 steps:

Pyroscope supports all major architectures and is very easy to install. For example, here is how you install on a mac:

# install pyroscope
brew install pyroscope-io/brew/pyroscope

# start pyroscope server:
pyroscope server

Send data to server via Pyroscope agent (language specific)
