SNMP OID(s) for System Board Exhaust Temperature

Question

I'm trying to set up some basic SNMP monitoring across all of our Dell servers - the idea is to generate a twice-hourly report of system board exhaust temps to see how much impact (if any) increasing the machine room temperature has.

I've used several of the OIDs from this list: https://www.dell.com/support/manuals/en-uk/openmanage-software-v9.4/om_snmp_9.4_ref_guide/temperature-probe-table?guid=guid-58484ab7-91d8-47ee-b4e0-07ed3610d752&lang=en-us, however all return "NoSuchObject" as data.

Any ideas on how I can get this working? For reference, I'm using the SNMP module in Powershell.

Example syntax is Get-SnmpData -IP -OID

Which server you have? Can you try below OID's .1.3.6.1.4.1.674.10892.5.4.700.20.1.6.1.3 .1.3.6.1.4.1.674.10892.5.4.700.20.1.6.1.4

Hi @DELL-Shine K,

Thanks for your reply.

We have hundreds of rackmount and blade servers spanning the last 4-5 generations, but the majority are 13G+14G

If you can give me an idea of which model/generation those are for, I can test it on one specifically. The server I tested the above on is an R630:

Get-snmpdata -IP -OID .1.3.6.1.4.1.674.10892.5.4.700.20.1.6.1.3

Data OID
---- ---
500 .1.3.6.1.4.1.674.10892.5.4.700.20.1.6.1.3

Get-snmpdata -IP -OID .1.3.6.1.4.1.674.10892.5.4.700.20.1.6.1.4

Data OID
---- ---
450 .1.3.6.1.4.1.674.10892.5.4.700.20.1.6.1.4

I'd assume 500 nor 450 is the exhaust temp, unless it displays figures multiplied by ten? But even then that would be higher than expected for the exhaust. Looking at the iDRAC web GUI, CPU1 and 2 match these figures if you multiply them by 10.

CPU1 Temp	50 °C (122.0 °F)
CPU2 Temp	45 °C (113.0 °F)

You can do get on OID '.1.3.6.1.4.1.674.10892.5.4.700.20.1.8' to get a list of temp probe and index for them. get on '.1.3.6.1.4.1.674.10892.5.4.700.20.1.6' will give the reading

Hi Shine K, I don't know how to do a get on these to get more OIDs, if you can explain. Or if you have a reference for where these OIDs came from, the two you gave me seem to work, but I need readings for 2 other probes and cpu temp and maybe some others for the dell poweredge 640.

Thanks

Hello, I also saw your similar thread answered on this https://dell.to/3Cn7llk;

I've also checked and found the same OID links as Charles and Dheeraj mentioned. In addition, might be also you can check this one https://dell.to/3Cn7lSm
