Differences between MicroProfile Metrics 1.0 and 2.0

The metrics reference list includes all the metrics that are available for Open Liberty.

Some metric names and types changed between MicroProfile Metrics 1.1 and MicroProfile Metrics 2.x, so the following table lists the MicroProfile Metrics 2.2 metric names and the corresponding MicroProfile Metrics 1.1 metric names. It also lists the corresponding Prometheus names and metric types:
