I'm looking for recommendations for good IT inventory tracking software.

It must track not only hardware assets (those are a dime-a-dozen) but also software, licenses, and support agreements.

It doesn't have to be free or open-source, if it's reasonably-priced and good value.

It should definitely run on UNIX, at least the back-end stuff.

I do *not* need automatic inventory-gathering capability.

Anyone know of anything that works for that?

(BTW, for those that don't know yet, yes this is my new full-time gig, and yes I'm still available for paid work through Avant.  Gratuitous plug: we also sell & support JIRA, Confluence and all the other Atlassian software.  Call us for all your DevOps needs.)
