rwbytype.d(1m) USER COMMANDS rwbytype.d(1m)NAMErwbytype.d - read/write bytes by vnode type. Uses DTrace.
SYNOPSISrwbytype.dDESCRIPTION
This program identifies the vnode type of read/write activity - whether
that is for regular files, sockets, character special devices, etc.
This is measuring at the application level, so file activity may well
be cached by the system.
Since this uses DTrace, only users with root privileges can run this
command.
EXAMPLES
This samples until Ctrl-C is hit.
# rwbytype.dFIELDS
PID process ID
CMD process name
VNODE vnode type (describes I/O type)
DIR direction, Read or Write
BYTES total bytes
DOCUMENTATION
See the DTraceToolkit for further documentation under the Docs direc‐
tory. The DTraceToolkit docs may include full worked examples with ver‐
bose descriptions explaining the output.
EXITrwbytype.d will sample until Ctrl-C is hit.
