Steps to reproduce:

1. Loaded Arista SNMP template, I have active alarm on "DOM Temperature Sensor for Ethernet28: Temperature is below the critical threshold"

Result:
See screenshot...

From what I can see the temperature reading is  
sensor.temp.valueentPhySensorValue.{#SNMPINDEX} 
1.3.6.1.2.1.99.1.1.1.4.{#SNMPINDEX}

In my case the reading is 325. Then there is preprocessing "custom multiplier 0.1"
this changes the reading to 32.5.
This pre processing does not happen on the reading for the max and min value.

,1.3.6.1.4.1.30065.3.12.1.1.1.2
this value for my Optic is 50, when checking on the CLI of the switch the Low Alarm Threshold (Celsius) is 5

It appears that we need to add the same preprocessing "custom multiplier 0.1" to the 
THRESHOLD_HI_WARN
THRESHOLD_HI_CRIT
THRESHOLD_LO_WARN
THRESHOLD_LO_CRIT
