syscallbypid.d(1m)                              USER COMMANDS                             syscallbypid.d(1m)



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.
