The OCDoctor is a tool that you can use to gather prerequisite and troubleshooting information about your systems. It's included in Ops Center, but you can also download it from here.
Update 4.38 was just released a couple of days ago. It has some new checks, including checking the remote database tablespace sizes and looking for lockfiles left over from prior upgrades. Also, if you run the doctor with the --update option from an Agent managed system, it'll pull the latest version from the Enterprise Controller. This could be handy if you're in a site with limited connectivity.
The OCDoctor chapter explains some of the things that you can do with the OC Doctor, so take a look and get the latest version. (Note that if you're using Ops Center in connected mode, the latest version is downloaded automatically.)
