NAME

syscallbypid.d - syscalls by process ID. Uses DTrace.

SYNOPSIS

syscallbypid.d

DESCRIPTION

This reports the number of each type of system call made by PID. This is useful to identify which process is causing the most system calls.

This is based on a script from DExplorer.

Since this uses DTrace, only users with root privileges can run this command.

EXAMPLES

This samples until Ctrl-C is hit.: # syscallbypid.d

FIELDS

PID: process ID
CMD: process name
SYSCALL: system call name
COUNT: number of system calls made in this sample

DOCUMENTATION

See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with verbose descriptions explaining the output.

EXIT

syscallbypid.d will sample until Ctrl-C is hit.
