# 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`
