title: Dell EMC Unisphere PowerMax: Masking View Volume Summary
agents: unisphere_powermax

description:
 This check monitors the volumes that belong to a masking view of a Dell
 EMC PowerMax storage array, queried via the Unisphere REST API special
 agent.

 For every masking view it reports the percentage of volumes in state
 {Ready} together with the absolute count of ready volumes versus the
 total number of volumes of that masking view.

 The check goes {WARN} or {CRIT} when the percentage of ready volumes
 drops below the configured lower levels. The defaults warn below 100%
 and go critical below 50%. Both levels can be adjusted with the rule
 "PowerMax Masking View Volume Summary". If no volume data is delivered by
 the agent the service becomes {UNKNOWN}.

 The masking view and the Symmetrix id are derived from the service item,
 so no identification data is stored in the discovered service parameters.

item:
 The Symmetrix id followed by the masking view name, joined with an
 underscore (for example {SYMMETRIX_000297600410_mv_example}).

discovery:
 One service is created for every combination of Symmetrix and masking
 view found in the agent output.
