With Dell OpenManage "OMSA" end of life how do we use WMI or SNMP to leverage the hardware status including the HDD's.

We use OMSA currently and via SNMP and Solarwinds that reads the hardware status via OMSA and gives us information around our hardware like below which includes all monitors whereas WMI does not give the same information, a few important ones are missing

SNMP

Whereas WMI has the following components

With OMSA's EOL we need to act and have removed OMSA from one server and have installed Dell iSM as this looked like it could use WMI to give out the hardware components status but we're getting errors via SolarWinds advising it can't see any hardware like it would normally, so are we missing something here or how do we get this working - so we try to leverage via the OS hostname and not directly to the iDRAC or anything and ideally we'd like to only get status via the OS name.

So ideally we need to interrogate the OS name of a server and leverage hardware status via WMI or SNMP will full components - how can that happen going forwards?

Your screenshots for SNMP and WMI look the same to me or and I missing something?

The below is from the article above. Looks like WINRM's WMI needs to be enabled manually.

Heres the WMI whitepaper

This might be useful to read. Some info regarding WMI here.

Ah - just noticed from your comments that I'd posted up the wrong picture for the WMI hardware view.

Here's the correct wMI view with the important stuff missing like HDD's / Battery etc.

WMI is working fine for monitoring however it's just the lack of hardware components that is presenting the issue.

We have already enabled the iSM. Cheers for the links.

I presume they are also missing when you click on the "Manage Sensors" button? If so you might need to log a case with SW support to assist.

You should be able to pull most of these details in by monitoring your (newer) iDRACs using SNMP.

If you use SNMP via the idrac you don't see Hardware under the resources at all - SNMP settings have been checked on the IDRAC and all is good.

I've been working through this too and found some more info:

OMSA populated the namespace ROOT\CIMV2\Dell with a number of DELL_* classes, whereas

iSM populates the namespace ROOT\CIMV2\DCIM with a number of DCIM_* classes

From this page it looks like SAM is only looking at the Dell namespace:

https://documentation.solarwinds.com/en/success_center/sam/content/sam-troubleshooting-a-wmi-node-sw3650.htm

To make matters worse, Dell 'enhanced' iSM from 5.2.0.0 to remove populating WMI:

Looks like SNMP using the iSM 'In-band SNMP Get' feature is the only way forward unless SolarWinds implements something like Redfish using the iSM 'iDRAC access via Host OS' port 1266 feature.

So after some back and forth between Dell and SolarWinds Dell have provided the correct namespace that should be being used, SolarWinds is using the incorrect namespace for a machine without OMSA - SolarWinds are aware of the EOL for OMSA and support for using “\\root\cimv2\dcim” namespace on iDRAC has been added for their list of tasks to work on for future releases which has been confirmed via support today so they are working towards a resolution on this for the near future which is perfect as the EOL for OMSA won't stop it working however it will most likely prove a security risk as any vulnerabilities on OMSA latest version will NOT be fixed.

This will also apply to iSM since Dell no longer support the functionality from 5.2.0.0 on.

SolarWinds would be better putting some effort into something like linking iDRAC IPs to nodes and pulling HW metrics directly from iDRAC.

jamieg

indeed and 100% agreed - to leverage via the idrac would be a better route for sure.
