Tracing System Calls with strace and ltrace
Go deeper into troubleshooting by tracing the system and library calls a process makes, revealing exactly where it stalls or fails.
When Metrics Are Not Enough
CPU, memory, and I/O tools tell you that something is slow. To learn why, you trace what a process actually asks the kernel to do. strace and ltrace open that window.
What strace Shows
strace records every system call: file opens, reads, network sends, and their return values, including errors.
