The Cache workspace displays cache statistics. This helps you, along with the other Memory workspaces, to identify disk performance problems through slow rates of data transfer from disk to memory and high disk usage.
This workspace includes an Activity chart and the Cache table view. Use the table view to view the number of times data is read into the cache prior to writing the data back to disk, the frequency of reads from cache pages using a Memory Descriptor List (MDL) to access the pages, and the number of pages the cache has flushed to disk. Additionally, IBM Tivoli Monitoring: Windows OS Agent provides a historical version of this workspace. You can request to view up to 24 hours of historical data for each component of this workspace. Based on the information that this workspace provides, you can recommend changes, set up situations, and verify that changes are improving performance.
