8 This file is used to generate a comprehensive list of Chrome histograms along
9 with a detailed description for each histogram.
11 Please pretty-print and validate your edits by running the pretty_print.py
12 and validate_format.py scripts in the same directory as this file before
13 uploading your change for review.

18 * The histograms section describes base histograms, giving their name,
19 and optionally their units or enum type, a short one-line summary,
20 and optionally a more detailed description.
21 * The enums section defines and documents the enumerated types referred to by
23 * The fieldtrials section defines active field trials and their groups, along
24 with their descriptions.
26 Each field trial lists the histograms that it affects. The complete list of
27 histograms is computed by appending the field trial group names to each of
28 the affected histograms. For example, define the following:
30 <histogram name="FileLoadLatency"/>
32 <fieldtrial name="SuperHttpExperiment">
33 <group name="SuperHttpEnabled"/>
34 <group name="SuperHttpDisabled"/>
35 <affected-histogram name="FileLoadLatency"/>
38 The complete list of histograms will be:
41 FileLoadLatency_SuperHttpEnabled
42 FileLoadLatency_SuperHttpDisabled
44 Field trial definitions can currently be used in any situation where multiple
45 suffixes need to be appended to a histogram name; they do not have to
46 correspond to actual field trials in the Chrome source code.
48 TODO(mlloyd): Refactor the XML so that field trials can be distinguished from
49 other types of suffix sets.

6507 The number of glyph pages present in the renderer when it commits a load.

6509 in the system by multiplying this number with the average number of
6510 renderers. Note that this typically won't count the glyph pages added as a
6511 result of the load that just committed, since layout will happen after the
6512 commit. There are 512 bytes per glyph page, but this number also very
6513 closely approximates the number of glyph width map pages in the same
6514 renderer. The only difference is that if you have font fallback, it will
6515 make a new glyph page and no width page, but in most common cases there is
6516 no fallback). Width pages are 1K each (256 floats), so you could think of
6517 this value as being the number of "1.5K units related to glyphs per

19451 incremented by 1. The page count bucket (i.e. bucket number 1) is always
