package io.opentelemetry.api.metrics
This package describes the Metrics API that can be used to record application Metrics.
The primary entry point to Metrics is the MeterProvider,
which allows the construction of a Meter. Instrumentated
libraries should construct a single Meter and register
`instruments` via the builders available on Meter.
There is a global instance of MeterProvider available for
scenarios where instrumentation authors are unable to obtain one by other means.
