112 # 'type' defines what the stat tells you. Types are:
113 # SCALAR: A simple scalar statistic that holds one value
114 # VECTOR: An array of statistic values. Such a something that
115 # is generated per-thread. Vectors exist to give averages,
116 # pdfs, cdfs, means, standard deviations, etc across the
118 # DIST: Is a distribution of data. When the statistic value is
119 # sampled, its value is counted in a particular bucket.
120 # Useful for keeping track of utilization of a resource.
121 # (e.g. fraction of time it is 25% used vs. 50% vs. 100%)
122 # VECTORDIST: Can be used when the distribution needs to be
123 # factored out into a per-thread distribution of data for
124 # example. It can still be summed across threads to find
125 # the total distribution.
126 # VECTOR2D: Can be used when you have a stat that is not only
127 # per-thread, but it is per-something else. Like
129 # FORMULA: This statistic is a formula, and its data must be
130 # looked up in the formula table, for indicating how to
131 # present its values.

133 # give a specific name to all of the data elements within a
135 # 'print' indicates whether this stat should be printed ever.
136 # (Unnamed stats don't usually get printed)
137 # 'prereq' only print the stat if the prereq is not zero.
138 # 'prec' number of decimal places to print
139 # 'nozero' don't print zero values
140 # 'nonan' don't print NaN values
141 # 'total' for vector type stats, print the total.
142 # 'pdf' for vector type stats, print the pdf.
143 # 'cdf' for vector type stats, print the cdf.
145 # The Following are for dist type stats:
146 # 'min' is the minimum bucket value. Anything less is an underflow.
147 # 'max' is the maximum bucket value. Anything more is an overflow.
