ML30 Gen10 ILO5 SNMP is different from ILO5's screens.

BunnyPon · ‎04-06-2023

This is a bit long winded, the upshot is, something, somewhere is buggy.

I have just spent a few hours puzzling over this mess, so I thought I would see if anyone else has noticed or can provide an explanation.

That or I am doing something wrong and should clearly go play with Dell hardware instead. If anyone has any insights into what I am doing wrong, please let me know. Note, I didn't try the RestAPI stuff, so I have no idea if that gives a different answer.

All of this should be trivially reproducible even if I was running a <cough-splurt> SUPPORTED OPERATING SYSTEM. I get the same results from a nearby box running ubuntu pointing at this server.

Exhibit 1, the Temperatures Page from an ML30 Gen10 ilo5 2.78

Exhibit 2, the lightly formatted output of telegraf running on the same server, looking at the ILO and specifically: "cpqHeTemperatureIndex, cpqHeTemperatureCelcius, cpqHeTemperatureThreshold" taken within a few seconds of the above screenshot.

Exhibit 4, mouse over the PCI 1 card:

Is it unrealistic to expect SNMP to give the same results as the ILO5 screen?

For example.

ILO says LOM is 53'c, nothing is even close on SNMP.
SNMP says 14 is 33'c, is that so?
ILO says PCI 1 is 44'c, SNMP hasn't a clue, mouse over says 64'c.
SNMP says 14 + 15 have a Threshold of 100'c, ILO has nothing with a threshold of 100'c
ILO says 26, 27, 28, 29 are all M2 Zone. This is rather neat as I didn't see 4 M2 zones at all, only the ILO card one. It's a bit moot, I have no M2 card, just the ILO's dedicated port card.
ILO has Critical temperatures, SNMP only has Cautions.

I would suspect that this is a feature, likely a long standing one that exists simply because no-one tried compare and contrast.

I can't Cat Today.

Greetings!

Confirm the Operating System being used for testing.
Configure SNMP by referring to the web link provided: https://support.hpe.com/hpesc/public/docDisplay?docLocale=en_US&docId=emr_na-a00026111en_us
Ensure the latest MIBs are installed: https://support.hpe.com/hpesc/public/docDisplay?docId=emr_na-c04272529
Update the iLO firmware to the latest revision, which is 2.81.
Verify the functionality of another agent, apart from telegraf.

@BPSingh

1) Confirm the Operating system being used.

This is Freebsd 13.1, but that is neither here no there.

I have a spare ML10 but until I can completely erase the firmware and turn it back into an HP, it's a boatanchor.

2) Configure SNMP ... link

Because you do not support FreeBSD, there is in AMS to install, As such, I expect to see the elements on the LEFT column under that URL.

3) Ensure the latest MIBs are installed.

The second URL gives me "upd11,80mib.tar.gz" Which is full of lots of files. I'll get to that in a second.

4) Update the ILO firmware...

Update the ILO from 2.78 to 2.81. Note that the Revision History says nothing what so ever about SNMP being wrong.

5) Verify the functionality of another agent, apart from telegraph.

I do hope you are prepared to lose a point. Nothing has changed.

BELOW, a screenshot from the ILO after being updated. Compare with the original one, a few minor changes in ambient.

next, an agent other than telegraf.

A quick diff with 2.78 shows no real changes but here are the relevant ones:

< SNMPv2-MIB::sysDescr.0 = STRING: Integrated Lights-Out 5 2.81 Mar 07 2023

Note, if the LOM is at 54'c, it doesn't want to tell anyone.

Have any of the MIBS changed? That's a bit of a merge nightmare as there are lots of filename differences. But no real change from the above.

SSH to the ILO, that's not telegraf is it?

This is the sensors from ssh, you can see that DeviceID matches except for 15-LOM, where the temperature reported by SSH is 34 but the image shows 54.

As they say, a picture is worth 1000 words.

Spot the difference.

All these values were obtained from the ILO directly. OS INDEPENDENT.

Left copied from the ILO web page. Right, from SSH.

simple excel.

My statement stands. "Something, somewhere is buggy."

Greetings!

If you see mismatch in temperature readings across iLO SSH and GUI, then kindly log a support ticket and share logs for further insvestigation.

@BunnyPon

I guess the case number you mentioned is a free case and not tied to the serial numbers of your product because serial number is confidential information and should not be shared in public forums. The reason why they do not show up in support center also. , So they recommend calling tech support to perform proper analysis. I got this info and I hope this helps you!

These are my opinions so use it at your own risk.

I'm seeing similar things on HPE ProLiant Gen10 servers with iLO5. Case number is 5374517319.

Apparently this is expected. According to the support engineer,

"I checked with the engineering team regarding this issue and as per there update.

The Temperatures on ILO5 GUI and SNMP MIB would not match.
The reason being, ILO5 used a Adjusted / Optimized Temperature readings than the RAW Temperature readings from the temperature sensors.ILO5 GUI is an aggregation of different sensor outputs. There will be a slight variation on the values. This is normal.

We would always recommend to rely on ILO temp than any sensor results from SNMP or third party tools. ILO better knows HPE Hardware
"

I was a bit surprised by this, as SNMP is an age-old protocol which you would think would have an accurate value regardless of what new features are added.

I asked to see if I could be provided with whatever the adjusted/optimized temperature reading formula is, but the response I got was "This is something Internal Logic to ILO5 for managing the server cooling. I guess, there is nothing we can share on this aspect.".

The recommendation was to use Redfish/the RESTful API to get the temperature values: https://support.hpe.com/hpesc/public/docDisplay?docId=c04423967

From the monitoring perspective, I now need to look into how to build these temperature checks in-house to get a reliable reading, instead of using built-in SNMP checks that are offered by practically all monitoring vendors out of the box. Totally understand the desire to improve/attempt to replace an older technology but at what cost to the customer?

I appreciate you trying to find answers too.

It is unusual that the ILO gives different results depending on how you ask it. Different values, or even completely fictitious sensors.

The reasoning seems bizarre since this implies that the ILO is about as honest and trustworthy as a voting machine.

And why would I want to use a heavyweight Redfish API that seems to be part of the HTTP with everything cult when I already have working SNMP from telegraf. To quote from that documentation: "The RESTfulAPI is designed using a REST architecture called HATEOS" They have that right.

Most people would have no need for Redfish in any shape, size or form, it's too complicated and too painful for J. Random Citizen.

And that's before we even mention the fictitious sensors showing up in the web interface *and* different ones in SNMP.
