PI shows only one temperature value per device. So what represents the one value if the device is a stack, VSS or/and has multiple temperature sensors?
I checked PIs SNMP requests to one of our C4506-E with SUP7. PI requested all SNMP values under entSensorValue (126.96.36.199.188.8.131.52.184.108.40.206.1.4), entSensorStatus.15 (220.127.116.11.18.104.22.168.22.214.171.124.1.5.15), ciscoEnvMonTemperatureStatusEntry.3 (126.96.36.199.188.8.131.52.184.108.40.206.3) and ciscoEnvMonTemperatureStatusEntry.4.1 (220.127.116.11.18.104.22.168.22.214.171.124.4.1). So, PI gets all temperature values, but displays only one.
2) Does PI generate a critical alarm if the temperature of one device exceeds its temperature threshold? I tried to test it with a C3750E by configuring
(config)#system env temperature threshold yellow 25
With this configuration, the switchs system temperature state was Yellow.
#show env temp status
System Temperature Value: 41 Degree Celsius
System Temperature State: YELLOW
Yellow Threshold : 34 Degree Celsius
Red Threshold : 59 Degree Celsius
However, the switch did not send a SNMP trap to PI. Also, PI did not recorgnizes a problem by its own. At least it did not generate an event for this.
If PI do not care about temperture thresholds, I can configure a Threshold monitoring in the Design > Monitor Configuration menu, but I don't know which thresholds I should configure, because it depends on the temperature PI displays (question 1).
