Perf Prof | Agent Skills Atlas

About this skill

使用perf-prof进行Linux系统问题分析。perf-prof是基于perfevent的系统级分析工具,事件在内存中实时处理,可长期运行。触发场景:(1) CPU使用率高、热点分析 (2) 进程状态异常(D/S状态多) (3) 延迟抖动、响应慢 (4) 内存泄露或增长异常 (5) 块设备IO慢 (6) 虚拟机性能问题 (7) 事件聚合统计 (8) 自定义脚本分析。核心分析器:profile(CPU采样)、task-state(进程状态)、multi-trace(延迟分析)、kmemleak(内存泄露)、blktrace(IO延迟)、top/sql(聚合统计)、kvm-exit(虚拟化退出)、rundelay(调度延迟)、syscalls(系统调用耗时)、python(自定义脚本分析)。适用于:性能问题定位、内核/应用开发调试、学习理解Linux内核机制(调度、内存、IO、中断等)。English: Linux system performance analysis with perf-prof, a perfevent-based tool for real-time in-memory event processing. Triggers: high CPU usage, hotspot profiling, process state issues (D/S states), latency spikes, slow response, memory leak detection, memory growth, block device IO slowness, VM performance issues, event aggregation, custom script analysis. Key profilers: profile (CPU sampling), task-state (process state), multi-trace (latency analysis), kmemleak (memory leak), blktrace (IO latency), top/sql (aggregation), kvm-exit (virtualization exit), rundelay (scheduling delay), syscalls (syscall latency), python (custom scripting).
