Example 1 with MetricID

use of org.eclipse.microprofile.metrics.MetricID in project Payara by payara.

the class TestUtils method parseMetricID.

/**
 * Parses text form of a {@link MetricID} back to object.

 * This supports both the result of calling {@link MetricID#toString()} as well as a simplified more user friendly form illustrated in the examples below:
 *
 * <pre>
 * my-metric-name
 * my-metric-name[tag=value,tag=value]
 * </pre>
 *
 * @param metric text form of a {@link MetricID}
 * @return
