Jinsight Guided Tour
Continuing with GCExample1, we'll now use the
Method Histogram view as one way to study the methods in
the sample trace.
The basic organization of the view is the same as in the Object Histogram View
introduced previously, except that here the blocks represent methods in a class.
| To open a Method Histogram View: |
-
Click on Workspace Window => Views => Histogram => Methods
-
Choose Histogram => Options => Sort Class Colors Now to reveal hotspots.
-
Choose Histogram => Options => Recalibrate Colors to highlight variances
among method activity.
-
Fly over the methods to see details.
|
| To see other coloring criteria: |
-
Choose Histogram => Method Colors => Base Time.
-
Choose Histogram => Method Colors => Cumulative Time.
-
Choose Histogram => Method Colors => Number of Calls.
|
| To see the caller(s) of a method: |
-
Right-click on a method of class java/lang/String (at the top).
-
Choose Show Callers. Zero or more green lines show the callers of
this method.
|
Use a similar technique to show the callees of a method.
| To show the callers or callees of all methods of
a class: |
-
Right-click on the class label java/lang/String.
-
Choose Show All Callers or Show All Callees. Green lines
show the callers or callees of this method.
|
| To clear the lines from the view: |
-
Right-click on empty space in the view.
