description:
 This check monitors the usage of the individual filesystems of a
 VMware vCenter Server Appliance (VCSA), such as the root, seat, db,
 dblog and log partitions. The data is retrieved by the special agent
 {agent_vcsa_health} from the appliance monitoring API.

 Upper levels on the used space can be configured via the ruleset
 "VCSA filesystem usage". The default levels are 80/90 percent, which
 matches the appliance's own warning threshold and leaves headroom before
 the point at which vCenter stops its main service to protect the
 database.

 The archive filesystem is excluded from these levels by default, because
 it is designed to fill and is documented as safe to ignore when high.
 Levels can be applied to it as well via the same ruleset.

 The percentage comes from the appliance's own utilization metric rather
 than being derived from the used and total values, whose declared units
 are not consistent between appliances. Absolute sizes are shown only when
 both underlying values were reported in the same unit.

item:
 The name of the filesystem.

discovery:
 One service is created for each filesystem reported by the appliance.
