ARISTA-ENTITY-SENSOR-MIB

Monitored by Observium

        This MIB module augments the entPhySensorTable of 
ENTITY-SENSOR-MIB to provide threshold information for 
various sensors in the system. For example, a given device
may have several voltage sensors as well as temperature
sensors each with appropriate threshold support to help
NMS systems detect and alert appropriately.
        
In addition, on systems where it is supported, if the 
sensor value crosses the supported threshold value the system
can generate appropriate notification as well.

Observium actively monitors this MIB

Observium uses this MIB in discovery or polling workflows on applicable devices.
