rwsnoop - snoop read/write events. Uses DTrace.
SYNOPSIS
rwsnoop [-jPtvZ] [-n name] [-p PID]
DESCRIPTION
This is measuring reads and writes at the application level. This matches the syscalls read, write, pread and pwrite.
Since this uses DTrace, only users with root privileges can run this command.
OPTIONS -j print project ID
-P print parent process ID
-t print timestamp, us
-v print time, string
-Z print zone ID
-n name
process name to track
-p PID PID to track
EXAMPLES

# rwsnoop
Print zone ID,
# rwsnoop -.Monitor processes named "bash", # rwsnoop -n bash
FIELDS

TIMESTR
time, string
ZONE zone ID
PROJ project ID
UID user ID
PID process ID
PPID parent process ID
CMD command name for the process
D direction, Read or Write
