Interface Summary

Interface	Description
Clock	Used to measure absolute and relative time.
Counter	Counters monitor monotonically increasing values.
DistributionSummary	Track the sample distribution of events.
FunctionCounter	A counter that tracks a monotonically increasing function.
FunctionTimer	A timer that tracks two monotonically increasing functions: one representing the count of events and one representing the total time spent in every event.
Gauge	A gauge tracks a value that may go up or down.
LongTaskTimer	A long task timer is used to track the total duration of all in-flight long-running tasks and the number of such tasks.
Meter	A named and dimensioned producer of one or more measurements.
Tag	Key/value pair representing a dimension of a meter used to classify and drill into measurements.
TimeGauge	A specialized gauge that tracks a time value, to be scaled to the base unit of time expected by each registry implementation.
Timer	Timer intended to track of a large number of short running events.
