This resource is accessed by clicking the R/W IOPS Ratio or Cache Hit Ratio label on the Performance Summary resource.

  • The R/W IOPS Ratio chart shows the ratio of read to write input/output operations per second (IOPS).
  • The Cache Hit Ratio chart shows the ratio of cache hits (where the data requested for processing is found in cache memory) to misses (where it is not), expressed as a percentage.

You can display performance data for the last hour, the last 12 hours, or the last 24 hours using the Zoom buttons, or set the start and end points from the historical data selection to select a custom period, by setting the start and end points from the historical data selection shown below the charts.
