Description

Description:

Opens "capture frame" dialog if current frame exceeds set threshold in seconds. One can indicate to either capture duration of a specific profiling selection or the total duration of the frame. The selection names can be obtained by expanding the profiling tree. Clicking on a tree item will highlight the item on the graph and vice versa. The GUI also provides method of copying of the displayed data to clipboard. Some of the selections:

Render	Main Thread	Visualize	Mjob
bgD3D	total memAl	visul	Mjob

ⓘ

Chrome export format:

Capturing to file also creates a .trace file, which can be imported into chrome://tracing (in chromium based webbrowsers), or https://ui.perfetto.dev/

The same format can be exported by pressing the "COPY ALL" button, in the capture frame UI, with Ctrl key being held down.

Syntax

Syntax:

diag_captureSlowFrame [section, threshold, frameSkip, toFile, continuousCounter]

Parameters:

section: String - case-sensitive

threshold: Number - section duration in seconds. 0 captures always IF the section you gave as section filter appears inside the given frame. "total" always appears, while "callExt" might not always appear for example

since 1.18

frameSkip: Number (Optional, default 0) - number of frames to ignore before measuring

since 2.20

toFile: Boolean - (Optional, default false) if true, doesn't open UI and writes straight to file. If logging to file, it automatically also outputs a .trace file. Note: even if false it might still force to file if it doesn't have a UI, like a server or HC

since 2.20

continuousCounter: Number (Optional, default 0) - captures N slow frames. 0 or 1 will only capture one frame - don't set it to negative! Can be aborted by running diag_captureFrame or another captureSlowFrame

Return Value:

Nothing

Examples

Example 1:

diag_captureSlowFrame ["total", 0.003];

Example 2:

diag_captureSlowFrame ["memAl", 0.0001, 30];

Example 3:

diag_captureSlowFrame ["total", 0, 0, false, 3]; // Will open the capture UI three times
