Package org.apache.accumulo.core.metrics

Interface MetricsProducer

public interface MetricsProducer

Prior to 2.1.0 Accumulo used the Hadoop Metrics2 framework. In 2.1.0 Accumulo migrated away from the Metrics2 framework to Micrometer. Micrometer suggests using a particular naming convention for the metrics. The table below contains a mapping of the old to new metric names.
