Hotspots

Last modified: 26 May 2024

Hotspots shows the list of methods from all selected threads sorted by execution time.

Use Hotspots in conjunction with other filters to determine "top" methods by a certain condition. For example, to see "top" methods by file operations time, select the File Operations event in Events.

Hotspots

1 The percentage of call execution time (total or own depending on the selected sorting) relative to the total selected time. If Follow selection in Call Tree is enabled, then relative to the total time of the call subtree selected in Call Tree.

2 Short method name.

3 Total / Own + System or Total / Own call execution time. See the details on how this time is calculated below.

4 Full method name.

Follow selection in Call Tree   – If this option is enabled, Hotspots are calculated for the node that is currently selected in Call Tree. Otherwise, Hotspots are calculated for the currently selected time intervals.

Hide system functions   – See the details on this option below.

Subsystems   – Subsystems allow you to quickly understand how the call time is distributed among various components: user and system code, WPF, LINQ, and others. The subsystems bar in Hotspots visualizes the data from the Subsystems filter.
