strace

Troubleshooting tool for tracing system calls

• Start tracing a specific PID

strace -p {{pid}}

• Trace a process and filter output by system call

strace -e {{system call name}} -p {{pid}}

• Start tracing and produce a summary of system calls at the end, instead of showing individual calls.

strace -c -p {{pid}}
