In November 2022, Grafana Labs announced the launch of Grafana Phlare, an open-source continuous profiling system that became part of its observability suite, complementing metrics, logs, and traces. Following Grafana Labs' acquisition of Pyroscope in March 2023, the Pyroscope and Grafana Phlare projects merged under the new name Grafana Pyroscope. Grafana Phlare is designed to be horizontally scalable, highly available, and multi-tenant, and it helps users understand resource usage to optimize application performance and cost. The tutorial video by Grafana Labs Principal Engineer Cyril Tovena guides users through starting with Phlare, highlighting its integration with Grafana, and demonstrating its visualization features, such as Flame graphs and Top tables, which allow users to analyze CPU usage and identify performance bottlenecks. Phlare profiles are stored for long-term retention and can be queried via Grafana, utilizing the same service discovery as Prometheus, and allowing seamless correlation with other observability data. The setup process involves using docker-compose to run services for visualizing the data, and the profiling language aligns with Prometheus metrics, enabling easy navigation for users familiar with Grafana's ecosystem.
