11 Please pretty-print and validate your edits by running the pretty_print.py

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 histogram_suffixes section provides a compact way of defining histograms
24 by applying affixes to existing histograms. This could be done recursively
25 and the max recursion depth is 5. See the example below for details on how it
28 Each histogram_suffixes tag lists the histograms that it affects. The complete
29 list of histograms is computed by appending (or prepending - see below) the
30 histogram_suffixes suffix names to each of the affected histograms. For example,
33 <histogram name="FileLoadLatency"/>
35 <histogram_suffixes name="SuperHttpExperiment">
36 <suffix name="SuperHttpEnabled"/>
37 <suffix name="SuperHttpDisabled"/>
38 <affected-histogram name="FileLoadLatency"/>
41 The complete list of histograms will be:
44 FileLoadLatency_SuperHttpEnabled
45 FileLoadLatency_SuperHttpDisabled
47 histogram_suffixes can also be used to insert affix in the middle. Example:
49 <histogram name="Prerender.Events"/>
51 <histogram_suffixes name="SuperHttpExperiment" ordering="prefix">
52 <suffix name="HoverStats50"/>
53 <affected-histogram name="Prerender.Events"/>
56 The complete list of histograms will be:
59 Prerender.HoverStats50_Events
61 When 'ordering="prefix"' is present in the histogram_suffixes tag, the suffix
62 will be inserted after the first dot separator of the affected-histogram name.
63 Therefore, the affected-histogram name has to have at least one dot in it.

252 <owner>dtrainor@chromium.org</owner>
254 When a user closes a tab an undo toast will popup on certain devices giving
255 the user the chance to undo closing that tab. This stat tracks how the user
256 interacts with that UI and what actions they take. A cold start means that
257 the undo bar wasn't showing when it was triggered to show again. A warm
258 start means that it was. Warm starts can happen when the user closes
259 multiple tabs close together. When the undo bar is dismissed, all closes
260 that were queued up to be undone are committed. This can happen either by a
261 timeout or by an action by the user to move to another part of the UI.

12777 The number of glyph pages present in the renderer when it commits a load.
12778 Since this is per-sub-process, you can get the average number of glyph pages
12779 in the system by multiplying this number with the average number of
12780 renderers. Note that this typically won't count the glyph pages added as a
12781 result of the load that just committed, since layout will happen after the
12782 commit. There are 512 bytes per glyph page, but this number also very
12783 closely approximates the number of glyph width map pages in the same
12784 renderer. The only difference is that if you have font fallback, it will
12785 make a new glyph page and no width page, but in most common cases there is
12786 no fallback). Width pages are 1K each (256 floats), so you could think of
12787 this value as being the number of "1.5K units related to glyphs per
12788 renderer per page load".

16846 When a preconnection is made, indicate what the motivation was.
16849 Currently, the most common (only?) motivations are SELF_REFERAL,

16851 second connection was available for a resource that either was never before
16852 seen, or has historically had no subresources. The LEARNED_REFERAL
16853 indicates that we "learned" that a subresource was commonly
16854 needed, and that motivated the TCP/IP preconnect. The OMNIBOX motivation
16855 happens when a search is being suggested, and we preconnect to the search
16856 provider. (WARNING: Prior to version 7.517.*, enums 7, 8, and 9 may be

23981 <owner>Please list the metric's owners. Add more owner tags as needed.</owner>
23983 Retries needed to enable a FET on tps65090 (AKA tpschrome). Tps65090 is a
23984 power management unit (PMU) used on many ARM Chromebooks. Until version ES7
23985 was rolled into production we would sometimes run into a problem where FET1
23986 (the FET used to switch on and off the backlight) wouldn't turn on properly.
23987 This problem was especially prevalent when the voltage was high (like when
23988 the device was plugged into the wall). Retrying by turning the FET off and
23989 on again is nearly always effective, so the kernel will retry up to 5 times
23990 (currently) and will also log the fact that it needed to retry. On newest
23991 kernels (kernel 3.8 and up) a kernel warning will be logged with WARN_ON if
23992 the FET still failed to turn on after 5 tries. Refer to the kernel warning
23993 reports to find that information. For more details about this bug refer to
23994 http://crbug.com/338657 and http://crosbug.com/p/16009. Note that we log
23995 retries on all 7 FETs even though we've only ever seen failures of FET1.

39003 Records usage of CSS properties used on a page, either statically or
39004 dynamically, from the time the page is initialised to when it is closed or
39005 navigated away from. Each property is counted at most once per page per
39009 Every time a CSS property is parsed on a page, that property is recorded as
39010 having been used. The histogram is updated with this data whenever a page is
39011 closed, or a page navigation happens. Each histogram bucket corresponds to a
39012 CSS property (eg width, border-radius). The exception is the bucket numbered
39013 '1' - this counts the number of pages that CSS properties were counted on.
39015 These numbers give the percentage of pages that use a CSS property. For
39016 example, if the 'border-radius' histogram bucket has a count of 250, and the
39017 page count bucket (i.e. bucket number 1) has a count of 1000 - this means
39018 that 1000 pages were recorded, and border-radius was used on 25% of those
39021 Internally, each WebCore::Page has a WebCore::UseCounter instance, with
39022 booleans recording use of each CSS property - one boolean per property. Upon
39023 destruction of the WebCore::Page (e.g. by the user closing the tab), or a
39024 page navigation happening, the histogram is updated. For each boolean that
39025 is set to True, the corresponding histogram bucket for that CSS property is
39026 incremented by 1. The page count bucket (i.e. bucket number 1) is always
39027 incremented by 1 on each histogram update.

50961 password manager do, what did the user do, and was the form submitted (and
50962 submitted successfully or not). The meaning of each value can be determined
50963 from the values in chrome/browser/password_manager/password_form_manager.h
