Looking for Inventory Management Software*

Hey,

I am currently looking for inventory management software that is agent based. Reason for this, is because I haven't found a single snmp based software that can poll down the information that we need, so if there is, then please help me out and guide me to it. This software can be open source or closed source, for all intents and purposes, as long as it has the features we need, it will be an option.

I am looking for software that can poll linux hardware information, smart status on hard drives, serial numbers of hard drives, motherboard, iDrac licensing for Dell Servers, metadata for software packages, repo changes, installed software packages, luks disk encryption status, and any other information that is provided is helpful.

Preferably, this can be agent based, but network based would be alright too, as long as it fits all the right checkboxes.

What I have gone over so far:
zabbix, samanage, prtg, glpi, Oracle, Symantec, Snipeit

(For the record, I cant even get in touch with someone at Oracle or Symantec)

Current platforms that we like, don't necessarily do all of what we want yet or could be done through an API:
ralph

I was just wondering what anyone here used, or what you may have used in the past, what you are looking into, and more!

If this is in the wrong section, please move it to the correct one, I thought this was the most appropriate area.
