All fan, temperature and voltage sensors are collected in this table. All these devices are similar in that they monitor 5 value ranges: low critical, low warning, normal, high warning, high critical. Notifications (trap messages) are sent whenever the monitored value moves from one value range to another. The guard points defining the 5 monitored regions (or range of values) are read-write allowing remote configuration by an SNMP management console.

There may be zero or more rows in this table. Each row in the table contains information about a single sensor. One column, uemSensorType, identifies the type of sensor as fan, temp or voltage. Another column, uemSensorStatus, identifies where in the 5 possible ranges the monitored device is currently operating within. Each row is linked to a parent EnvMonitor row to further identify its location within the server.
