The Trending reports are described in detail in
The Trending reports can help you answer questions about long-term trends and activity. The
Trending reports query the MySQL database to display events. Two types of Trending interactive
reports can be displayed:
•
Event Growth
•
Daily Event Rates
Event Growth
The Event Growth tab compares the number of occurrences of events between two time periods.
By default, the time period is one day (comparing the last 24 hour period with the previous 24
hour period, as shown in the figure below).
Also by default, Event Growth charts (Column, Bar, Pie) show the Top 10 and Bottom 10 events —
the Top 10 events are those that showed the greatest positive growth over the time period, while
the Bottom 10 events showed the least (or negative) growth over the time period. You can select
the number of events to show, and you can choose to show only the Top n, only the Bottom n, or
both Top and Bottom.
You can interactively change the time periods displayed and other filter criteria, by changing the
time period value in the Filter drop-down list or by configuring a custom filter. For more
information about creating a custom filter, see
The Event Growth Table shows all event counts for the two time periods, not just the Top and/or
Bottom n events.
