Hermes, a versatile time-series profiling tool, offers comprehensive system performance analysis. It operates by executing periodic or oneshot jobs as defined in the configurations, thereby monitoring performance metrics. To minimize impact on system performance, Hermes intelligently skips metric collection if the system loading remains below defined thresholds. This feature ensures that the profiling service can seamlessly run in production environments without causing any disruptions. At present, Hermes supports various approaches, including perf, ftrace, and ebpf, to gather detailed information for performance analysis. This diverse range of supported methods enhances the tool's effectiveness in providing insightful performance metrics. During this presentation, Chengen will delve into the concept and implementation with meticulous detail, providing a comprehensive overview of the subject matter.
