Continuous profiling is emerging as a critical component of observability alongside traditional tools like logs, metrics, and traces, offering deep insights into resource usage and performance at the code level. Ryan Perry, a founder of Grafana Pyroscope, emphasized its value during a GrafanaCON 2025 presentation, highlighting its ability to enhance system performance, reduce costs, and proactively identify bottlenecks. Profiling, particularly when used with Grafana's Profiles Drilldown, can optimize the return on investment by improving throughput and user experience while minimizing resource expenses. Companies like Uber and Shopify have successfully implemented continuous profiling to achieve significant cost savings and infrastructure efficiencies. Perry underscored that profiling is distinct in its ability to optimize both the value received from data and the associated costs, offering a low-overhead solution that provides visibility into resource allocation and potential inefficiencies. By integrating profiling with other observability tools, organizations can comprehensively address system performance and cost challenges.
