| geckoview.page_load_time | timing_distribution | The time taken to load a page. This includes all static contents, no dynamic content. Loading of about: pages is not counted. Back back navigation (sometimes via BFCache) is included which is a source of bimodality due to the <50ms load times. | Bug 1584109 | never | ||

| gfx.checkerboard.duration | timing_distribution | The duration of a checkerboard event. Checkerboarding is when painting has not kept up with asynchronous panning and zooming so the compositor has to display a "checkerboard pattern" (or in practice, the background color) rather than the actual page content. | Bug 1584109 | never | ||
| gfx.checkerboard.peak_pixel_count | custom_distribution | The peak number of CSS pixels that checkerboarded during a checkerboard event. The minimum value of the largest histogram bucket is the size of a 4k display with maximum APZ zooming. | Bug 1584109 | never | ||
| gfx.checkerboard.potential_duration | timing_distribution | The total amount of time that we could reasonably be checkerboarding. This is the union of two possibly-intersecting sets of time periods: The first set is that in which checkerboarding was actually happening, since by definition it could potentially be happening. The second set is that in which the APZC is actively transforming content in the compositor, since it could potentially transform it so as to display checkerboarding to the user. Combined with other information, this allows us to meaningfully say how frequently users actually enncounters checkerboarding. | Bug 1584109 | never | ||
| gfx.checkerboard.severity | custom_distribution | An opaque measurement of the severity of a checkerboard event. This doesn't have units, it's just useful for comparing two checkerboard events to see which one is worse, for some implementation-specific definition of "worse". The larger the value, the worse the checkerboarding. | Bug 1584109 | never | ||
| gfx.composite_time | timing_distribution | The time taken to composite a frame. On non-webrender this is the time taken in CompositorBridgeParent::CompositeToTarget(). On webrender, this is the time taken from the start of WebRenderBridgeParent::CompositeToTarget(), until the render thread has rendered the frame (in RenderThread::HandleFrameOneDoc()). |
Bug 1580129 | never | ||
| gfx.content.frame_time.from_paint | custom_distribution | The time, in percentage of a vsync interval, spent from beginning a paint in the content process until that frame is presented in the compositor. | Bug 1584109 | never | ||
| gfx.content.frame_time.from_vsync | custom_distribution | The time, in percentage of a vsync interval, spent from the vsync that started a paint in the content process until that frame is presented in the compositor. | Bug 1584109 | never | ||
| gfx.content.frame_time.reason | labeled_counter | The reason that gfx.content.frame_time.from_paint recorded a slow (>200ms) result, if any. |
Bug 1584109 |
|
never | |
| gfx.content.frame_time.with_svg | custom_distribution | The time, in percentage of a vsync interval, spent from beginning a paint in the content process until that frame is presented in the compositor, for frames that contained an SVG to be drawn by webrender. | Bug 1584109 | never | ||
| gfx.content.frame_time.without_resource_upload | custom_distribution | The time, in percentage of a vsync interval, spent from beginning a paint in the content process until that frame is presented in the compositor by webrender, excluding time spent uploading resources. | Bug 1584109 | never | ||
| gfx.content.frame_time.without_upload | custom_distribution | The time, in percentage of a vsync interval, spent from beginning a paint in the content process until that frame is presented in the compositor by webrender, excluding time spent uploading any content. | Bug 1584109 | never | ||
| gfx.content.full_paint_time | timing_distribution | Time spent in the full paint pipeline for content until it's ready for composition. For non-webrender this includes paint_time, plus rasterization if OMTP is enabled. For webrender, this includes paint_time, plus scene building time. |
Bug 1584109 | never | ||
| gfx.content.paint_time | timing_distribution | Time spent in the main-thread paint pipeline for content. For non-webrender, this includes display list building, layer building, and when OMTP is disabled, rasterization. For webrender, this includes display list building, and webrender display list building. | Bug 1584109 | never | ||
| gfx.display.count | quantity | Amount of displays connected to the device | Bug 1594145 |
|
never | |

| gfx.status.compositor | string | Name of the graphics compositor in use. Possible values are "opengl, d3d11, client, webrender or basic" | Bug 1594145 | never | ||
| gfx.status.headless | boolean | Boolean indicated whether graphics is running in headless (no display) mode | Bug 1594145 | never | ||
| gfx.status.last_compositor_gecko_version | string | The gecko version at the last time a compositor was initialized, and therefore when gfx_status_compositor was last updated. Due to gfx_status_compositor's user lifetime we see lots of unexpected values for the current gecko version. We believe this is because the user has not opened a tab since they were updated to a version where webrender should be enabled on their device. This can be used to verify that theory. | Bug 1704842 | never | ||
| gfx.webrender.framebuild_time | timing_distribution | The time taken to build a webrender frame. This involves calculating the visibility of primitives, requesting resources, and building the render passes which will be used to render the frame. | Bug 1584109 | never | ||
| gfx.webrender.scenebuild_time | timing_distribution | The time taken to build a webrender scene. This occurs each time webrender receives a new display list. This additionally includes blob rasterization time. | Bug 1584109 | never | ||
| gfx.webrender.sceneswap_time | timing_distribution | The time taken to do a webrender scene swap. This is book-keeping that APZ must perform once webrender has built a new scene. | Bug 1584109 | never | ||
