Class CloudWatchMetricConfig

java.lang.Object

com.amazonaws.metrics.internal.cloudwatch.CloudWatchMetricConfig

@NotThreadSafe
public class CloudWatchMetricConfig
extends Object

Configuration for the default AWS SDK collection implementation. This class is not intended to be used directly by client code except for cases where the default behavior of the internal Amazon CloudWatch collector implementation needs to be customized.

Example:

 /**
  * My custom Request Metric Collector by extending from the internal Amazon CloudWatch
  * implementation.
  */
 static class MyCloudWatchMetricCollector extends
         CloudWatchRequestMetricCollector {
     MyCloudWatchMetricCollector(CloudWatchMetricConfig config) {
         super(config);
     }
 }
 MyCloudWatchMetricCollector myCollector = new MyCloudWatchMetricCollector(
         new CloudWatchMetricConfig()
                 .withQueuePollTimeoutMilli(60000)
                 .withMetricQueueSize(1000)
                 .withCredentialsProvider(
                         new DefaultAWSCredentialsProviderChain())
                 .withCloudWatchEndPoint("monitoring.us-west-2.amazonaws.com")
                 .withPredefinedMetrics(
                         new HashSet<Field>(Arrays.asList(Field.HttpRequestTime,
                                 Field.ResponseProcessingTime))));
 myCollector.start();
 // Enable the AWS SDK level request metric collection with a custom collector
 AwsSdkMetrics.setRequestMetricCollector(myCollector);

Field Detail

DEFAULT_METRICS_QSIZE

public static final int DEFAULT_METRICS_QSIZE

Default metrics queue size. If the queue size exceeds this value, then excessive metrics will be dropped to prevent resource exhaustion.
