description:
 Monitors the cache-protection supercapacitor pack of each Dell PowerVault ME5
 controller. One service is created per controller and covers that pack's charge
 level, capacitance, internal resistance, pack voltage and individual cell
 voltages.

 The supercapacitor holds cached write data during a power loss, so its
 condition matters for data integrity. Capacitance and internal resistance are
 graphed as wear indicators, and the service raises if any of the pack's sensors
 reports a status other than OK, naming the sensor concerned.

 Conditions are configurable via the "Dell PowerVault ME5 supercapacitor"
 ruleset.

item:
 The controller the pack belongs to (for example {"Controller A"}).

discovery:
 One service is created per controller that reports supercapacitor sensors.
