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 2.20 also accepts the threshold as String parameter with number plus s/ms/us/ns/fps suffix.
Note: The capture happens "when the section/scope duration is larger/longer than this", but with fps it is "when smaller/lower".

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 ["total", "0.003s"];

Example 3:

diag_captureSlowFrame ["total", "3ms"];

Example 4:

diag_captureSlowFrame ["total", "333fps"];

Example 5:

diag_captureSlowFrame ["memAl", 0.0001, 30];

Example 6:

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