How to monitor hardware, applications and warranty time?

Hi,

I want to use a tool to control the health and warranty time of our servers.

I have physical servers with vmware, hyperv core, one windows and one with linux and as they are old servers we don't have iDrac.

We installed Dell Open Manager a long time ago but it was very bad, the access works only via the web and IE needed to use so we aborted.

We are looking to resume because we are Dell partners.

I was reading about Dell Open Manager Essentials which has been discontinued and is now Dell Open Manager Enterprise, but do I understand that it is a paid version?

What options do I have for our legacy and not iDrac scenario?

Thanks.
