High-intent search queries and answers about installing and using this skill.
CPU profiling with perf records process execution samples to identify hot spots. Generating a flame graph visually maps which functions consume the most execution time during slow application performance.
System call tracing with strace monitors and logs all system and library calls made by a specific Linux process. It captures execution flow to troubleshoot slow applications and pinpoint I/O bottlenecks.
Memory analysis with valgrind, pmap, and smem detects memory leaks and maps process memory usage. These tools provide detailed statistics and mapping to identify memory leaks and optimize resource utilization.
Yes, vmstat, iostat, and pidstat provide real-time system and process-level I/O metrics. They report continuous visibility into virtual memory, disk, and CPU activity to troubleshoot slow applications and optimize resource utilization.
Profiling relies on standard Linux performance tools like perf, strace, valgrind, vmstat, and iostat. While many are included by default, some distributions require installing specific packages to enable full CPU profiling and memory analysis capabilities.
