Advanced Aggregation
The advanced aggregation function is based on process aggregation and allows
lightening the Event Timeline chart for big traces above 1K processes. By default,
the function is automatically enabled for traces with above 768 processes, but you
can change this threshold using the Edit Configuration Dialog Box.
Advanced Aggregation Settings in the Edit Configuration Dialog:

When you enable this function, all processes are divided into a set of serial
groups. Each group has certain count of processes (except for the last one) and
corresponds to a single vertical frame on the
Event Timeline
chart. The
default frame size is 512 displayed processes. You can change this value in the Edit
Configuration Dialog Box. These processes groups are called
All_Processes_(Visible_
N1
-N2
)- is the start of displayed range of processes in the groupN1
- is the end of the rangeN2
For example, the first advanced aggregation group is called
All_Processes
by
default (Visible_0-4)
.The advanced aggregation groups contain hidden (non-visible separately) processes
as two additionally aggregated groups:
- aggregated_above
- aggregated_below
They are displayed on the top and on the bottom of a frame respectively.

Top of the Next Advanced Aggregation Frame:

A vertical scrollbar of
Event Timeline
chart enables you to scroll among all
advanced aggregation frames.When a jump to the next frame happens, Intel Trace Analyzer loads the corresponding
process group. The chart may be not available in a short period.
