Specifying cache metrics collection for virtual machines and disks
Cache metrics measure disk caching performance: average read and write latency, hit rate, insertion rate, and so on. Flash Accel rolls up caching performance statistics for disks into averages or totals for the virtual machine on which the disks are configured.
Note: Although cache metrics collection has only a minor impact on caching performance, it is still a good idea to disable metrics collection on virtual machines and disks for which you do not need to collect statistics.
