The trace always highlights one event. This is the selected event (green is the default highlighting color).
Information about the selected event is shown on the first status line:
This textual representation of each event consists of seven parts, representing the following information:
1 | event type |
2 | method name |
3 | host name |
4 | process ID![]() ![]() |
5 | on a client trace: client ID1 on an object trace: object ID ![]() |
6 | on a client trace: Client on an object trace: object name |
7 | position on the trace |
1For C++ clients, the client ID is the thread ID for the client.
You can change which event is selected by clicking another event with the left mouse button.
Most OLT actions apply to the selected event. In that sense, the selected event acts as a kind of cursor on the trace. For example, pressing the arrow keys on your keyboard moves the selected status to the next event in the direction of the arrow. To access the pop-up menu for a selected event, click the right mouse button. From the pop-up menu, you can tag the selected event, or add it to the method breakpoint list.
A selected event is always visible. If you scroll a selected event past the edge of the trace, that event loses its selected status and the OLT viewer automatically selects another event to take its place.
