This file is used to generate a comprehensive list of Chrome histograms along
with a detailed description for each histogram.
Please pretty-print and validate your edits by running the pretty_print.py
and validate_format.py scripts in the same directory as this file before
uploading your change for review.
Take a moment to page through the contents of this file. You will find
three sections:
* The histograms section describes base histograms, giving their name,
and optionally their units or enum type, a short one-line summary,
and optionally a more detailed description.
* The enums section defines and documents the enumerated types referred to by
the histograms.
* The histogram_suffixes section provides a compact way of defining histograms
by applying affixes to existing histograms. This could be done recursively
and the max recursion depth is 5. See the example below for details on how it
works.
Each histogram_suffixes tag lists the histograms that it affects. The complete
list of histograms is computed by appending (or prepending - see below) the
histogram_suffixes suffix names to each of the affected histograms. For example,
define the following:
<histogram name="FileLoadLatency"/>
<histogram_suffixes name="SuperHttpExperiment">
<suffix name="SuperHttpEnabled"/>
<suffix name="SuperHttpDisabled"/>
<affected-histogram name="FileLoadLatency"/>
</histogram_suffixes>
The complete list of histograms will be:
FileLoadLatency
FileLoadLatency_SuperHttpEnabled
FileLoadLatency_SuperHttpDisabled
histogram_suffixes can also be used to insert affix in the middle. Example:
<histogram name="Prerender.Events"/>
<histogram_suffixes name="SuperHttpExperiment" ordering="prefix">
<suffix name="HoverStats50"/>
<affected-histogram name="Prerender.Events"/>
</histogram_suffixes>
The complete list of histograms will be:
Prerender.Events
Prerender.HoverStats50_Events
When 'ordering="prefix"' is present in the histogram_suffixes tag, the suffix
will be inserted after the first dot separator of the affected-histogram name.
Therefore, the affected-histogram name has to have at least one dot in it.

multiple tabs close together. When the undo bar is dismissed, all closes
that were queued up to be undone are committed. This can happen either by a
timeout or by an action by the user to move to another part of the UI.

When Chrome tries to access the user's Address Book, OSX presents a blocking
dialog which disrupts the user experience. A new Chrome feature has been
introduced wherein Chrome only shows this blocking dialog if the user
explicitly asked Chrome to access the user's Address Book. If a form's field
looks like it might support Autofill suggestions from the user's Address
Book and there are no other suggestions, Chrome shows an Autofill entry that
prompts the user to give Chrome access to the user's Address Book. This
histogram tracks the frequency that this Autofill entry is presented, and
the frequency that this Autofill entry is selected.

In some cases, such as when content arrives with embedded references to
other servers, the prefetch system can't (or doesn't) attempt to pre-resolve
the hostnames. As an example, a visit to www.cnn.com will fetch content
with references to about 12 additional hostnames, none of which are
currently anticipated. Such resolutions are termed &quot;Unexpected
Resolutions,&quot; and the durations associated with those DNS resolutions
are shown below. Future features may attempt to learn (from prior
experience locally, or from server provided hints), what secondary hostname
resolutions should be done when a primary resolution (or navigation) takes
place. This histogram shows what the potential savings are that
&quot;remain on the table&quot; until we employ some of these more advanced
features.

In some cases, such as when content arrives with embedded references to
other servers, or when a page (such as one in SSL) preclude scanning and
prefetching, the prefetch system can't (or doesn't) attempt to pre-resolve
the hostnames. As an example, a visit to www.cnn.com will fetch content
with references to about 12 additional hostnames, none of which might be
anticipated. Similarly, clicking on a link in an SSL page won't be
anticipated (since scanning in not allowed by default). Such resolutions are
termed &quot;Unexpected Resolutions,&quot; and the durations associated with
those navigation induced DNS resolutions are shown below. If a referring
URL is available for the navigation, the relationship to the referring URL
was recorded, and future navigations to the referring hostname would have
induced a pre-resolution of hostname that caused an entry below. Such any
entry may facilitate future listing in the ReferredPositiveHit histogram.

<owner>dmikurube@chromium.org</owner>
<owner>kenjibaheux@google.com</owner>
<summary>
The number of glyph pages present in the renderer when it commits a load.
Since this is per-sub-process, you can get the average number of glyph pages
in the system by multiplying this number with the average number of
renderers. Note that this typically won't count the glyph pages added as a
result of the load that just committed, since layout will happen after the
commit. There are 512 bytes per glyph page, but this number also very
closely approximates the number of glyph width map pages in the same
renderer. The only difference is that if you have font fallback, it will
make a new glyph page and no width page, but in most common cases there is
no fallback). Width pages are 1K each (256 floats), so you could think of
this value as being the number of &quot;1.5K units related to glyphs per
renderer per page load&quot;.

Currently, the most common (only?) motivations are SELF_REFERAL,
LEARNED_REFERAL and OMNIBOX. The SELF_REFERAL indicates that we made sure a
second connection was available for a resource that either was never before
seen, or has historically had no subresources. The LEARNED_REFERAL
indicates that we &quot;learned&quot; that a subresource was commonly
needed, and that motivated the TCP/IP preconnect. The OMNIBOX motivation
happens when a search is being suggested, and we preconnect to the search
provider. (WARNING: Prior to version 7.517.*, enums 7, 8, and 9 may be
confused, as EARLY_LOAD_MOTIVATED was inserted new 6 value.)

This histogram summarizes information about a 21 packet sequence, indicating
for each of the 21 possible prefixes of this pattern, how many packets were
received in that prefix. The first range uses buckets 0 and 1, and it
describes the 1st packet in the sequence. It indicates if the first packet
was missing (bucket 0), or the first packet was present (bucket 1). The
second range uses buckets 2 through 4, and describes the first 2 packets in
the prefix of this sequence. It indicates if there were no packets received
in the first two packets (bucket 2), or there was one out of two packets
received (bucket 3), or if there was two out of tow received (bucket 4).
etc. etc. Reading this histogram may require post-processing in a spread
sheet, but can indicate the potential value of using FEC packets to convey
data.

registers of the TSU6721 chip: ADC (07h), Device Type 3 (15h), Device Type 2
(0Bh), Device Type 1 (0Ah). Device Type 1/2/3 is a bitmap and most of bits
are mutually exclusive (excepted VBUS debounce). ADC is the 5-bit value of
the ID pin, but for most types (as in Device Type), there are only one or
two possible ID pin connections/values. The datasheet can be found here:

<histogram name="Platform.Tps65090Retries">
<owner>Please list the metric's owners. Add more owner tags as needed.</owner>
<summary>
Retries needed to enable a FET on tps65090 (AKA tpschrome). Tps65090 is a
power management unit (PMU) used on many ARM Chromebooks. Until version ES7
was rolled into production we would sometimes run into a problem where FET1
(the FET used to switch on and off the backlight) wouldn't turn on properly.
This problem was especially prevalent when the voltage was high (like when
the device was plugged into the wall). Retrying by turning the FET off and
on again is nearly always effective, so the kernel will retry up to 5 times
(currently) and will also log the fact that it needed to retry. On newest
kernels (kernel 3.8 and up) a kernel warning will be logged with WARN_ON if
the FET still failed to turn on after 5 tries. Refer to the kernel warning
reports to find that information. For more details about this bug refer to
http://crbug.com/338657 and http://crosbug.com/p/16009. Note that we log
retries on all 7 FETs even though we've only ever seen failures of FET1.

</summary>
<details>
Every time a CSS property is parsed on a page, that property is recorded as
having been used. The histogram is updated with this data whenever a page is
closed, or a page navigation happens. Each histogram bucket corresponds to a
CSS property (eg width, border-radius). The exception is the bucket numbered
'1' - this counts the number of pages that CSS properties were counted on.
These numbers give the percentage of pages that use a CSS property. For
example, if the 'border-radius' histogram bucket has a count of 250, and the
page count bucket (i.e. bucket number 1) has a count of 1000 - this means
that 1000 pages were recorded, and border-radius was used on 25% of those
pages.
Internally, each WebCore::Page has a WebCore::UseCounter instance, with
booleans recording use of each CSS property - one boolean per property. Upon
destruction of the WebCore::Page (e.g. by the user closing the tab), or a
page navigation happening, the histogram is updated. For each boolean that
is set to True, the corresponding histogram bucket for that CSS property is
incremented by 1. The page count bucket (i.e. bucket number 1) is always
incremented by 1 on each histogram update.

Deprecated as of 8/2013. This histogram only considered the leaf certificate
expiry date as a proxy for whether a certificate was in-scope for the BRs,
but did not consider the issuance date. As some CAs have issued long-lived
certs prior to the BRs, this disproportionately reported those certs as
being subject to the BRs, but non-compliant, when in reality they're not
subject.
