2.7 Business Monitor
This section describes best practices for performance with Business Monitor V8.0.
2.7.1 Event processing
2.7.2 Dashboard
A major factor in event processing performance is tuning the Business Monitor database.
Ensure adequate buffer pool sizes to minimize disk reading activity and placement of the
database logs, which ideally is on a physically separate disk subsystem from the database
table spaces.
By default, events are delivered from CEI to the monitor database, bypassing an intermediate
queue. We suggest using this default delivery style for better performance because it avoids
an additional persistence step in the flow.
For additional background, see “Receiving events using table-based event delivery” in the
IBM Business Monitor V8.0 information center:

The platform requirements of Business Space and the Business Monitor widgets on the
dashboard are relatively modest compared to the Business Monitor server and the database
server. The most important consideration for good dashboard performance is to size and
configure the database server correctly. Be sure that it has enough processor capacity for
anticipated data mining queries, enough memory for buffer pools, and plenty of disk arms.
2.7.3 Database server
Both event processing and dashboard rely on a fast, well-tuned database server for good
performance. The design of the Business Monitor assumes that any customer using it has
strong onsite database administrator skills. It is important to apply the database tuning
suggestions beginning in 4.13, “General database tuning” on page 80.
