For example, I get:
0 host:~# sa -m

spampd 6 223.03re 1.41cp 0avio 33627k
nobody 1364 1.88re 0.37cp 0avio 1118k
These processes are definitely reading and writing to disk so I expect a non-zero value for disk i/o related statistics.
Is there a kernel flag or compile flag or command option to get a value for "avio" (also "tio" is not even listed)?
Thank you!
