During timeline profiling, dotTrace collects various application data: time data, memory allocation data, and data about raised exceptions. Your work in Timeline Viewer starts with selecting one of these subjects for further analysis.
You can choose the following subjects in the Analysis Subject filter:
The collected time data.
When the Time subject is selected, Timeline Viewer works with time intervals. The length of time intervals is measured in ms.
The collected data about memory allocation.
When the Memory Allocation subject is selected, Timeline Viewer works with memory allocation events. These are point events as they have no extension in time. The size of memory allocated by such point events is measured in MB.
The collected data about raised exceptions.
When the Exceptions subject is selected, Timeline Viewer works with exception point events.
