Designing Reports
Using 5-minute aggregation enables near real-time dashboard reports by collapsing report data,
within each 5-minute time interval, into a single record. BAM then performs calculations on fewer
table rows than without aggregation. Also, since BAM aggregates report data every 5 minutes, the
aggregation process does not have to deal with as much data as when a 30-minute aggregation
interval is used. Provide additional performance improvement by filtering the aggregation report to
include current data only since the last time the aggregation engine ran.
Refreshing the dashboard
BAM dashboards can be configured to refresh after a certain interval of time. Refreshing a dashboard
consumes system resources. Choose a refresh interval that meets the business requirement to see
updated data and considers the frequency with which the data changes. For low volumes of long
running processes, a refresh interval of every few days can suffice. For have high volumes of rapidly
changing processes, use more frequent refresh intervals.
