Flash Accel PowerShell cmdlets : Performance metrics reported by the Flash Accel PowerShell cmdlets

Performance metrics reported by the Flash Accel PowerShell cmdlets
Flash Accel PowerShell cmdlets offer a more extensive set of cache performance statisticsthan the Flash Accel Management Console. Use these metrics to perform fine-grained analysis of server-side caching performance. Metrics are available for the overall cache and for disks.
Metrics reset interval
Metrics are collected, calculated, and averaged over the period of time specified in the MetricsResetInterval parameter of the Set-FAOptions cmdlet. The default is 60 seconds.
Metrics that display a count, such as ReadOps, and metrics that display an average latency, such as ReadLatencyPerOp or AvgHitLatency, are calculated over the specified interval. At the end of each interval, all metrics are collected and stored for retrieval. After being stored, the counters are cleared and collection begins for the next interval.
Setting MetricsResetInterval to a lower value will increase the point-in-time accuracy of the metrics but use more CPU. Setting it to a higher value will lower CPU usage but lessen point-in-time accuracy.
