How can you tell how much a Solaris box is swapping? At what point do page in and page out become a problem? Here is a vmstat output.

io_waitread
io_waitread(3) Library Functions Manual io_waitread(3)NAME
io_waitread - read from a descriptor
SYNTAX
#include <io.h>
int io_waitread(int64 fd,char* buf,int64 len);
DESCRIPTION
io_waitread tries to read len bytes of data from descriptor fd into buf[0], buf[1], ..., buf[len-1]. (The effects are undefined if len is 0
or smaller.) There are several possible results:
o o_waitread returns an integer between 1 and len: This number of bytes was available for immediate reading; the bytes were read into the
beginning of buf. Note that this number can be, and often is, smaller than len; you must not assume that io_waitread always succeeds in
reading exactly len bytes.
o io_waitread returns 0: No bytes were read, because the descriptor is at end of file. For example, this descriptor has reached the end of
a disk file, or is reading an empty pipe that has been closed by all writers.
o io_waitread returns -3, setting errno to something other than EAGAIN: No bytes were read, because the read attempt encountered a persis-
tent error, such as a serious disk failure (EIO), an unreachable network (ENETUNREACH), or an invalid descriptor number (EBADF).
