1 The following is an example fo the rwbytype.d script.
4 We run rwbytype.d for a few seconds then hit Ctrl-C,
7 Tracing... Hit Ctrl-C to end.
9 PID CMD VTYPE DIR BYTES
24 10357 more chr W 96925
25 10357 more fifo R 97280
27 10356 grep fifo W 117760
28 2357 sshd sock W 118972
29 10356 grep reg R 147645
31 Here we can see that the grep process with PID 10356 read 147645 bytes
32 from "regular" files. These are I/O bytes at the application level, so
33 much of these read bytes would have been cached by the filesystem page cache.
35 vnode file types are listed in /usr/include/sys/vnode.h, and give an idea of
36 what the file descriptor refers to.
