Monitoring Hub Performance

Using the EMM-E6 Hub View

Figure 2-6. The EMM-E6’s Device, Network, Module, and Port Menus

Hub performance data available through these menus includes:

•

Device, Network, Module, and Port status descriptions.

•

Network, Module, and Port statistics, which provide a complete breakdown of
packet activity.

•

Network-, Module-, and Port-level pie charts, graphs, and meters, for a
graphic representation of the types and levels of traffic passing through the
hub. (For more information about pie charts, graphs, and meters, see the
Charts, Graphs, and Meters

chapter in the SPMA Tools Guide.)

Port Display Form

You can change the type of information displayed for each port in the hub by
using the Port Display Form option on the Device, Network, and Module menus.

NOTE

Graphing capabilities are provided by an application that is included in HP Network
Node Manager and IBM NetView; therefore, graphs are only available when SPMA is
run in conjunction with one of these network management platforms. If you are running
SPMA in a stand-alone mode or in conjunction with SunNet Manager or Solstice
Enterprise Manager, no graphing capabilities are available and no graph-related options
will be displayed on buttons or menus. Note that the screens displayed in this guide will
include the graph-related options where they are available; please disregard these
references if they do not apply.
