- * 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.
