snmp query to 9300 switches to find out power supply status

[vijayS]

does any one know how to query the 2nd PS state . we use a monitoring tool called auvik and use oid for query.  1.3.6.1.4.1.9.9.13.1.4.1.2 oid is the powersupply state but if i just want the 2nd PS or 2nd switch ( on a stack) power supply states?

  - Try to snmpwalk the oid partially as in  1.3.6.1.4.1.9.9.13.1 and check the result,

The OID you are looking at is the Fan status. 

1.3.6.1.4.1.9.9.13.1.5.1 is the table for the PS status

If you walk 1.3.6.1.4.1.9.9.13.1.5.1.2 you will get the ID for each power supply in a switch stack.

For example one of my switch stacks have 2 switches, ids 1015 and 1016 are PS 1 and 2 in switch 1 where 2015 and 2016 are PS 1 and 2 in switch 2. 

1.3.6.1.4.1.9.9.13.1.5.1.3 is the PS state table and when I walk it I see values for all PS and I can match the ID to the PS status that I am looking for. 

So if I wanted the status of Switch 2 PS 2 I would use the OID 1.3.6.1.4.1.9.9.13.1.5.1.3.2016

thank you both of you @marce1000 @Ben Walters 

i was able to figure that out. may i ask a question about c8500L edge router.  i cant find enviroment related MIB. wondering whats the mib for powersupply, Fan , temperature.  I was able to find out the oid for pw/fan/temperature using entPhysicalDescr  but to find out the status, i only see this entPhySensorOperStatus.  which is a sensor status.  is that same as the actual status of pw/fan /temp or is it just a status of the sensor that monitors the pw/fan .

[Ben Walters]

The entPhySensorOperStatus is the status of the sensor itself.

To get the values the sensor is reporting you need to use entPhySensorValue. This will give you the actual values the sensor sees and then you need to cross reference that with entPhySensorType, entPhySensorScale and entPhySensorPrecision to determine what those values actually represent.
