mountford	9a15f08b3a	Add Truth subjects for incrementable and event metrics ... This CL adds Truth framework subjects to some metrics in the Stackdriver metrics library, in a contrib subpackage. It doesn't deal with gauge metrics, and for event metrics, the assertions can only be that a metric has or does not have a distribution for a particular set of label values. Asserting more fine-grained propositions regarding the distribution will require a distribution subject. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=149112692	2017-03-07 13:46:38 -05:00

shikhman	91f8b6da38	Change to metrics to keep track of when the metric value was first set ... This CL also adds IncrementableMetric#reset() methods to allow resetting the value and start timestamp of IncrementableMetrics. This is necessary because some backends, like Stackdriver, use non-monotonic changes in cumulative metric values to detect timeseries restarts. Tracking and re-setting the start timestamp allows users to track mostly monotonic metrics which may have non-monotonic discontinuities. See https://cloud.google.com/monitoring/api/ref_v3/rest/v3/TimeSeries#Point for more details. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=130795229	2016-08-22 14:44:28 -04:00
