The response time breakdown
report shows a table for an aggregation of all instances of a selected
page element.
About this task
Only data that is collected by the data collection infrastructure
is displayed. If a computer does not have the data collection infrastructure
installed or running, no data is displayed from that computer.
Procedure
To begin to analyze response time breakdown statistics:
- Choose a simple layout, tree layout, or UML layout by clicking
the Layout toolbar button, the first toolbar
button in the upper right corner of the view. The tree layout shows
the following hierarchy, in order: host, application, component, package,
class, and method. The tree layout helps you identify which
tier in your enterprise environment has the slowest response time.
The simple layout is a flattened version of the tree layout. The simple
layout provides a quick and easy way to see the slowest or fastest
methods. The UML layout shows a UML sequence diagram of the collected
data. The default layout is the simple layout. Click a column heading
to sort the table by that column. Drag the columns to change the order
in which the columns are displayed. Except for the first column in
the tree layout, all of the columns are moveable. Four
results are displayed for each object: Base Time, Average Base Time,
Cumulative Time, and Calls. All times are in seconds. Base Time is
the time spent inside this object, excluding time spent in other objects
that the selected object invokes. Average Base Time is the time spent
inside this object, excluding time spent in other objects that the
selected object invokes, divided by the number of calls. Cumulative
Time is the time spent inside this object and in other objects that
the selected object invokes. Calls are the number of times the selected
object is invoked by any other object. The exact URL of the selected
page element is displayed before the table.
- The toolbar in the upper right corner enables you to change
the table display and export the results.
- Click Manage Filters, the second
toolbar button in the upper right corner, to open the Filters window.
There you can add, edit, or remove filters that are applied to the
displayed results. For
more information, see Filtering.
- Click Select Columns, the third
toolbar button in the upper right corner, to open the Select
Columns page. There you can select which columns are displayed
in the table. These settings are saved with the current workspace,
and are applied to all response time breakdown tables in the workspace.
- Click Percent Format, the fourth
toolbar button in the upper right corner, to toggle the display between
percentages and absolute values.
- Click Open Source, the fifth
toolbar button in the upper right corner, to jump to the source code
(if available) in your workspace. You must first select a method before
clicking Open Source.
- Click Report, the last toolbar
button in the upper right corner, to open the New Report window.
There you can export the response time breakdown table to comma-separated
values (CSV), HTML, or XML formats.
- Use the navigation information in the upper left corner
to navigate back to previous views.
