languagejava
package org.apache.ignite.metric;

public interface IgniteMetrics extends Iterable<ReadOnlyMetricRegistry> {
    MetricRegistry customRegistry(String registryName);
    @Nullable ReadOnlyMetricRegistry findRegistry(String registryName);

}

Names like "LongMetric" or "ObjectMetric" we already have in the package "org.apache.ignite.spi.metric".
