Which is the most effective metric for identifying performance issues?
A.
Latency
B.
TOPS
C.
Throughput
D.
Percent utilization
E.
Capacity
Explanation:
*CPU: Percent Utilization
The appliance CPUs can reach 100% utilization, which may or may not be a problem. For some
performance tests the appliance is delibrately driven to 100% CPU utilization to measure it at
peak performance.
*The Disks statistic is used to display the heat map for disks broken down by percent utilization.
This is the best way to identify when pool disks are under heavy load. It may also identify
problem disks that are beginning to perform poorly, before their behavior triggers a fault and
automatic removal from the pool.
