Question
how to monitor system calls for a process?
Solution
Check strace
In the simplest case strace runs the specified command until it exits. It intercepts and records the system calls which are called by a process and the signals which are received by a process. The name of each system call, its arguments and its return value are printed on standard error or to the file specified with the -o option.
Each line in the trace contains the system call name, followed by its arguments in parentheses and its return value.
