Yandex has released Perforator as an open-source tool. It’s used internally to analyze the performance of most of the company’s services, including large-scale systems.
Perforator is a continuous profiling tool. It helps developers find performance issues in their applications by collecting and analyzing runtime data.
There are two main ways to use the tool. The simplest method is to run Perforator locally. Users can download or build the binary, then run the command:
sudo perforator record -a --duration=60s
After 60 seconds, the tool automatically opens a profile report in the browser.
For more advanced use cases, Perforator can also run on Kubernetes clusters. This setup is more complex but designed to be straightforward. Yandex has provided documentation to help users deploy it with just a few commands.
Yandex continues to share tools used in its own infrastructure to support the broader developer community. With Perforator now open-sourced, developers have access to a production-grade profiler for monitoring performance in real time.
More information, setup instructions, and source code are available in the official Perforator documentation.
