CLS_IO_STATISTICS structure (clfs.h)

  • Article

Defines the statistics that are reported by GetLogIoStatistics. Initially, statistics packets report only flush statistics, including the frequency of data and metadata flushes on a physical log and the amount of data and metadata flushed. The flush statistics are defined by the following I/O statistics packet types.

Syntax

  CLS_IO_STATISTICS_HEADER hdrIoStats;
  ULONGLONG                cFlush;

  ULONGLONG                cMetaFlush;
