The Samples Mode Thread Summary window displays information about an application thread profiled in samples mode. The window is divided into 2 sections. The top section displays information about the thread itself. The bottom section displays a table of information about every root frame executed by the thread. Clicking on a row in the table will open the Samples Frame Detail Window and display detailed information about the frame. Many bits of information are displayed in fields in all three sections. Descriptions of these are summarized in the following tables.
Table 5.6. Thread Fields
| Field Name | Field Description |
|---|---|
| Thread | This is the name of the thread. |
| Samples | This is the number of samples where the thread was found to be executing. Note that there is currently a bug in Sun's JVM that causes this number to not include samples where the thread was sleeping. |
| % of Total Samples | This is the percentage of the total samples taken in which the thread was executing. |
Table 5.7. Root Frame Fields
