description:
 Reports array-wide performance for a Dell PowerVault ME5 system: total IOPS and
 throughput summed across both controllers, the read and write split derived
 from the cumulative counters, and the average response time.

 Response time is taken from the host port statistics, since that is where the
 array reports service times, and is weighted by each port's IOPS so that idle
 standby paths do not distort the figure. Controller CPU load and write cache
 utilisation are also reported.

 IOPS, throughput and response time are graphed with their read and write
 components. Optional upper levels on each are available via the "Dell
 PowerVault ME5 system performance" ruleset and are off by default.

discovery:
 One service is created per array.
