strace
Troubleshooting tool for tracing system calls.
- Start tracing a specific process by its PID:
strace -p {{pid}}
- Trace a process and filter output by system call:
strace -p {{pid}} -e {{system call name}}
- Count time, calls, and errors for each system call and report a summary on program exit:
strace -p {{pid}} -c
- Show the time spent in every system call:
strace -p {{pid}} -T
- Start tracing a program by executing it:
strace {{program}}
