Examples with ServerMetrics org.apache.hadoop.hbase.ServerMetrics used on opensource projects

Example 36 with ServerMetrics

use of org.apache.hadoop.hbase.ServerMetrics in project hbase by apache.

the class TestReplicationStatusSink method getLatestSinkMetric.

private ReplicationLoadSink getLatestSinkMetric(Admin admin, ServerName server) throws IOException {
    ClusterMetrics metrics = admin.getClusterMetrics(EnumSet.of(ClusterMetrics.Option.LIVE_SERVERS));
    ServerMetrics sm = metrics.getLiveServerMetrics().get(server);
    return sm.getReplicationLoadSink();
}
