[CentOS] Tracking updates

Hi all,

I don't know if exists what I'm searching for, or just making the wrong questions to google.

I'm searching some kind of tracking system to software updates. If one server is administrated by more than 2 persons, having control of what updates have been installed, and what version of that application is running after the update. Making manual documentation is ok for one server, but doing this for several servers is a big amount of time, and relies on the admin to have the time to do so, but automating this would be great.

I someone doing something to have track of the updates? Any recommendation?

Cheers,

Martín
