8.3.4
Maximum number of instance is 15
The Entity for a given event varies according to what entity the environmental sensor is monitoring.
For example, a typical managed system board can have temperature monitoring associated with the
system board and with the main processor. Thus, the Entity IDs and Entity Instance values for these
would be Entity ID=7, Entity Instance=1 for ‘main system board’ and Entity ID=3, Entity Instance=1 for
‘processor 1’, respectively.
