示例1: StorageProxy
import org.apache.cassandra.metrics.ClientRequestMetrics; //导入依赖的package包/类
public StorageProxy(APIClient client) {
super(MBEAN_NAME, client, new ClientRequestMetrics("Read", "storage_proxy/metrics/read"),
new ClientRequestMetrics("RangeSlice", "/storage_proxy/metrics/range"),
new ClientRequestMetrics("Write", "storage_proxy/metrics/write"),
new CASClientRequestMetrics("CASWrite", "storage_proxy/metrics/cas_write"),
new CASClientRequestMetrics("CASRead", "storage_proxy/metrics/cas_read"));
}
示例2: travel
import org.apache.cassandra.metrics.ClientRequestMetrics; //导入依赖的package包/类
/**
* Performs the actual traveling of a graph. This could be complex, let's do it step by step
*/
public static List<Row> travel(TravelCommand command, ConsistencyLevel consistency_level)
throws UnavailableException, IsBootstrappingException, ReadTimeoutException, InvalidRequestException
{
if (StorageService.instance.isBootstrapMode())
{
readMetrics.unavailables.mark();

} finally

//this could be very important for profiling, but currently, i have not time to figure out how it works.
long latency = System.nanoTime() - start;
//readMetrics.addNano(latency);
// TODO avoid giving every command the same latency number. Can fix this in CASSADRA-5329
}
