perf-prof

Linux performance profiling, tracing, and latency diagnosis

Diagnoses Linux system performance problems using 30+ low-overhead profilers for CPU sampling, memory leaks, scheduling delays, I/O latency, and KVM virtualization exits. Processes kernel events in memory in real time without writing data to disk, eliminating heavy storage overhead. Guides step-by-step root-cause analysis from symptom detection to flame graphs and latency breakdowns.

Frequently Asked Questions

FAQPage Schema
How to install perf-prof?▼

Run `npx skills add OpenCloudOS/perf-prof --all -g -y` in your terminal to install all skills in this suite globally.

How to find the cause of high CPU usage on Linux?▼

Use the profile profiler to sample CPU usage with call graphs, then generate a flame graph to instantly see which functions consume the most cycles.

How to detect memory leaks in the Linux kernel?▼

The kmemleak profiler tracks allocation and free events with stack traces, pinpointing exactly where memory is allocated but never released.

Can perf-prof diagnose slow disk I/O and latency spikes?▼

Yes. The blktrace profiler tracks the full I/O request lifecycle, while multi-trace and rundelay analyze scheduling and event latency step by step.

Does perf-prof work on older Linux kernels?▼

Yes. It only requires perf_event support and runs safely in user space, making it compatible with older kernels and suitable for long-term production monitoring.
