/* Core stats collection API's. The following concepts are used:
* Aggregation: A collection of values. Census supports the following
aggregation types:
Sum - a single summation type. Typically used for keeping (e.g.)
counts of events.
Distribution - statistical distribution information, used for
recording average, standard deviation etc.
Histogram - a histogram of measurements falling in defined bucket
boundaries.
Window - a count of events that happen in reolling time window.
New aggregation types can be added by the user, if desired (see
census_register_aggregation()).
* Metric: Each measurement is for a single metric. Examples include RPC
latency, CPU seconds consumed, and bytes transmitted.
* View: A view is a combination of a metric, a tag set (in which the tag
values are regular expressions) and a set of aggregations. When a
measurement for a metric matches the view tags, it is recorded (for each
unique set of tags) against each aggregation. Each metric can have an
arbitrary number of views by which it will be broken down.
* Resource: Users record measurements for a single resource. Examples
include RPC latency, CPU seconds consumed, and bytes transmitted.
* Aggregation: An aggregation of a set of measurements. Census supports the
following aggregation types:
* Distribution - statistical distribution information, used for
recording average, standard deviation etc. Can include a histogram.
* Interval - a count of events that happen in a rolling time window.
* View: A view is a combination of a Resource, a set of tag keys and an
Aggregation. When a measurement for a Resource matches the View tags, it is
recorded (for each unique set of tag values) using the Aggregation type.
Each resource can have an arbitrary number of views by which it will be
broken down.
Census uses protos to define each of the above, and output results. This
ensures unification across the different language and runtime
implementations. The proto definitions can be found in src/proto/census.
