RHEL 8 Monitoring from SCOM 2012 R2

Question

Is it possible to monitor RHEL 8 with SCOM 2012 R2 UR14 ?

We have installed SCX agent 2019 scx-1.6.4-7.x86_64 manually and signed it manually.

While discovering it from Console we are getting below error

The server certificate on the destination computer (xxxxxxxxxxxxxxxxxxxxxx:1270) has the following errors:
Encountered an internal error in the SSL library.
It is possible that:

1. The destination certificate is signed by another certificate authority not trusted by the management server.
2. The destination has an invalid certificate, e.g., its common name (CN) does not match the fully qualified domain name (FQDN) used for the connection. The FQDN used for the connection is: xxxxxxxxxxxxxxxxxxxxxxx
3. The servers in the resource pool have not been configured to trust certificates signed by other servers in the pool.

WinRm commands shows :

WSManFault
Message = The server certificate on the destination computer (xxxxxxxxxxxxxxxxx:1270) has the following errors:
Encountered an internal error in the SSL library.

Error number: -2147012721 0x80072F8F
A security error occurred

OpenSSL Version is : openssl-1.1.1c-15.el8.x86_64

Anyone experienced this situation and able to monitor RHEL 8 with SCOM 2012 R2 UR14 ?

@Aman Bansal , Based as I know, SCOM 2012 R2 can only monitor Red Hat Enterprise Linux Server 4, Red Hat Enterprise Linux Server 5, Red Hat Enterprise Linux Server 6, and Red Hat Enterprise Linux 7 operating systems. For RHEL 8, it is not supported.

Here is a request posted in user voice, we can refer to it:
https://systemcenterom.uservoice.com/forums/293064-general-operations-manager-feedback/suggestions/38023954-red-hat-enterprise-linux-8-support-rhel-8

For Operations Manager 2019 UR1, it supports RHEL 8. We can use the universal management pack to discover and monitor RHEL 8. For more details, we can see the following link:
https://learn.microsoft.com/en-us/system-center/scom/whats-new-in-om?view=sc-om-2019#new-features-in-operations-manager-2019-ur1

Given the situation, we suggest to consider upgrading our operation manager to the latest version.

Hope it can help.

Hi @Aman Bansal ,

I can only confirm what Crystal stated: It is not supported and I am not quite sure that you can even get them monitored. While with SCOM 2019 you can monitor older Linux versions (even if officially they are not supported) the other way around (monitor newer Linux versions with SCOM 2012 R2) is not possible (protocols, agent version and many other factors).
My recommendation would be also to upgrade your SCOM deployment to a newer version (SCOM 2019) and then add those systems.

yes that is what they say... and that is true with centos etc too.... well sort of.

I actually have rocky 8.5 and oracle 8.9 in 2012 which in theory you cant.| ie
