Orion Internal Rules for Hardware sensors?

Good question, 

I was wondering if there was a "global setting" on a per device model basis.

I have the same question. I have two identical sensors with (apparently) different thresholds. One has a temp of 95 and is currently critical. The other is 111 and the status is OK. I understand that I can override the defaults but I'd really like to know what the defaults are so I can make adjustments before they alert.

I too have this same question.  Did anyone get an answer?

might be set by the device?

if you look  at entPhysicalTable you get the sensors (on an ASR920 anyway); on the entSensorValueTable a 'status is reported, and SW might be using the 'ok' value

 entSensorType entSensorScale entSensorPrecision entSensorValue entSensorStatus entSensorValueTimeStamp entSensorValueUpdateRate entSensorMeasuredEntity
       amperes          units                  0              0              ok          400:3:22:34.23               60 seconds                       6
       voltsDC          units                  0              0              ok          400:3:22:34.23               60 seconds                       6
       voltsAC          units                  0              0              ok          400:3:22:34.23               60 seconds                       6
         watts          units                  0              0              ok          400:3:22:34.23               60 seconds                       6
       celsius          units                  0              0              ok          400:3:22:34.23               60 seconds                       6

we have the something similar for low power alarms for SFP -- the SFP reported the actual power and the limits, and then the chassis decides if there is high/low power issue.

Hi I_LIKE_EGGS,

Does your issue regarding this has been resolved? If yes, can you share to us the resolution? We are encountering the same error. Appreciate you immediate feedback. Thank you in advance.

Hi fellas,

i didn't get any answer for this in the end. apologizes  for the lack of response on this.

i think i have worked out how thresholds work and what the internal rule is, so just like SolarWinds, Cisco has its own built in thresholds for example:

say you have a power sensor and its running normal at a value of 1000 this value is an integer that is used to compare predefined values on the device.

so lets say the current value of 1000 falls in to the brackets of 1200 - 1300 then you will get a warning hardware sensor this is the same for if the value falls into the predefined critical thresholds. 

I can only assume that 'Use Orion defaults' is simply mimicking  what Cisco is doing and comparing one OID value to another OID value and based on the value it falls in determines the state of the hardware.

i would suggest doing an SNMP walk on the device finding these threshold values and find the current value and compare them manually unfortunately i didn't get to the bottom of this but if you can find the thresholds and check the current value you will know if its a vendor problem or with SolarWinds.  

the above is just my assumption but if you manage to get to the root please comment back

Just curious if anyone has seen this issue on cards that are installed without SFPs but still reporting back bad data?
