Analyze Linux system issues with perf-prof. perf-prof is a system-level analysis tool built on perf_event; events are processed in memory in real time and it can run for long periods with low overhead. Typical trigger scenarios: (1) high CPU usage and hotspot analysis (2) abnormal process states (many D/S states) (3) latency jitter or slow responses (4) memory leaks or abnormal growth (5) slow block device I/O (6) virtual machine performance issues (7) event aggregation and statistics (8) custom script analysis. Core analyzers: profile (CPU sampling), task-state (process state analysis), multi-trace (latency analysis), kmemleak (memory leak detection), blktrace (I/O latency), top/sql (aggregation/statistics), kvm-exit (virtualization exits), rundelay (scheduling delay), syscalls (system call timing), python (custom script analysis). Suitable for performance debugging, kernel/application development and debugging, and learning or understanding Linux kernel mechanisms (scheduling, memory, I/O, interrupts, etc.).
