AsyncReadManagerSummaryMetrics A summary of the current metrics data.
Gets a summary of the metrics collected for AsyncReadManager read operations since you started data collection or last cleared the metrics data.
The returned AsyncReadManagerSummaryMetrics object provides overall statistics about the collected data. Call GetMetrics to get the underlying metrics data used for the summary.
Set the flags parameter to clear all data after returning the summary. This has the same affect as calling ClearCompletedMetrics.

AsyncReadManagerSummaryMetrics
A summary of the current metric data, filtered by the specified metricsFilters.
Gets a filtered summary of the metrics collected for AsyncReadManager read operations since you started data collection or last cleared the metrics data.
This function filters the metrics collected for AsyncReadManager read operations and provides a summary based on the filtered data. See AsyncReadManagerMetricsFilters.ctor for information about filter creation.
