Uses of ScanMetrics in org.apache.hadoop.hbase.client

Fields in org.apache.hadoop.hbase.client declared as ScanMetrics

Modifier and Type	Field and Description
private ScanMetrics	AsyncClientScanner.scanMetrics
protected ScanMetrics	AbstractClientScanner.scanMetrics
private ScanMetrics	AsyncScanSingleRegionRpcRetryingCaller.scanMetrics
private ScanMetrics	AsyncRpcRetryingCallerFactory.ScanSingleRegionCallerBuilder.scanMetrics
protected ScanMetrics	ScannerCallable.scanMetrics
private ScanMetrics	AsyncTableResultScanner.scanMetrics

Methods in org.apache.hadoop.hbase.client that return ScanMetrics

Modifier and Type	Method and Description
ScanMetrics	AbstractClientScanner.getScanMetrics() Used internally accumulating metrics on scan.
ScanMetrics	Scan.getScanMetrics() Deprecated. Use ResultScanner.getScanMetrics() instead. And notice that, please do not use this method and ResultScanner.getScanMetrics() together, the metrics will be messed up.
ScanMetrics	ResultScanner.getScanMetrics() Returns the scan metrics, or null if we do not enable metrics.
ScanMetrics	AsyncTableResultScanner.getScanMetrics()

Methods in org.apache.hadoop.hbase.client with parameters of type ScanMetrics

Modifier and Type	Method and Description
(package private) static void	ConnectionUtils.incRegionCountMetrics(ScanMetrics scanMetrics)
(package private) static void	ConnectionUtils.incRPCCallsMetrics(ScanMetrics scanMetrics, boolean isRegionServerRemote)
(package private) static void	ConnectionUtils.incRPCRetriesMetrics(ScanMetrics scanMetrics, boolean isRegionServerRemote)
AsyncRpcRetryingCallerFactory.ScanSingleRegionCallerBuilder	AsyncRpcRetryingCallerFactory.ScanSingleRegionCallerBuilder.metrics(ScanMetrics scanMetrics)
void	AsyncTableResultScanner.onScanMetricsCreated(ScanMetrics scanMetrics)
default void	ScanResultConsumerBase.onScanMetricsCreated(ScanMetrics scanMetrics) If scan.isScanMetricsEnabled() returns true, then this method will be called prior to all other methods in this interface to give you the ScanMetrics instance for this scan operation.
(package private) static void	ConnectionUtils.updateResultsMetrics(ScanMetrics scanMetrics, Result[] rrs, boolean isRegionServerRemote)
(package private) static void	ConnectionUtils.updateServerSideMetrics(ScanMetrics scanMetrics, org.apache.hadoop.hbase.shaded.protobuf.generated.ClientProtos.ScanResponse response) Use the scan metrics returned by the server to add to the identically named counters in the client side metrics.
