This view represents page I/Os that occurred while running stored procedures
during the most recent sample interval. For each stored procedure that
generated page I/Os during the sample interval, it shows the stored procedure
name and ID, together with the name and ID of the database that contains the
procedure. If page I/Os were produced when no stored procedure was active,
those I/Os are associated with procedure ID and database ID values of zero.
This view also shows, on a per stored procedure level, the total page I/Os, the
percentage of page I/O requests that could be satisfied by the Adaptive Server
data caches, and the number of logical page reads, physical page reads, and
page writes generated while executing the stored procedures during the most
recent sample interval.

This view shows the CPU utilization, page I/Os, and current process state for
all processes in the Adaptive Server.
For the most recent sample interval, the login name, Process ID and Kernel
Process ID are given for each process, together with its current process state.
The view also presents each process's connect time, total page I/Os and CPU
utilization time, accumulated since the start of the recording session.
