and optionally a more detailed description.
* The enums section defines and documents the enumerated types referred to by
the histograms.
-* The fieldtrials section defines active field trials and their groups, along
- with their descriptions.
+* 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 field trial lists the histograms that it affects. The complete list of
-histograms is computed by appending the field trial group names to each of
-the affected histograms. For example, define the following:
+Each histogram_suffixes tag lists the histograms that it affects. The complete
+list of histograms is computed by appending (or prepending - see blow) the
+histogram_suffixes suffix names to each of the affected histograms. For example,
+define the following:
<histogram name="FileLoadLatency"/>
- <fieldtrial name="SuperHttpExperiment">
- <group name="SuperHttpEnabled"/>
- <group name="SuperHttpDisabled"/>
+ <histogram_suffixes name="SuperHttpExperiment">
+ <suffix name="SuperHttpEnabled"/>
+ <suffix name="SuperHttpDisabled"/>
<affected-histogram name="FileLoadLatency"/>
- </fieldtrial>
+ </histogram_suffixes>
The complete list of histograms will be:
FileLoadLatency_SuperHttpEnabled
FileLoadLatency_SuperHttpDisabled
-Field trial definitions can currently be used in any situation where multiple
-suffixes need to be appended to a histogram name; they do not have to
-correspond to actual field trials in the Chrome source code.
+histogram_suffixes can also be used to insert affix in the middle. Example:
-TODO(mlloyd): Refactor the XML so that field trials can be distinguished from
-other types of suffix sets.
+ <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.
