which lists total counts, counts during the last sample period, and
the "per second" count for a variety of subsystem requests, abends,

You can use the HTML navigation feature to navigate
from one workspace to another, while passing context information to
the next workspace. The workspaces that belong to the same functional
unit are linked using HTML navigation. Tivoli Enterprise Portal workspaces are grouped
into the following units: Thread Summary workspaces, Thread Detail
workspaces, and Statistics workspaces.
Based on the information that this workspace provides,
you can recommend changes, set up situations, and verify that your
recommended changes improve system performance.
