You get a phone call.  If there is a problem, users are very quick to point it out.  If nobody is complaining, it isn't a problem.

Call the DBA and System Administrator.

Before you post that you are the DBA or System Administrator, please don't.

This question is way to vague to answer in a Q&A site like this.

Narrow down what specfic system part is showing signs of stress:
Memory, Disk or CPU.

That is half the battle right there.  Once you figure that out, dig deeper.

For example:
Are you licensed for ADDM and AWR?
Are you licensed for the Diagnostics or Performance packs?
Are you familiar with StatsPack?

From strictly a database perspective, most DBAs have collected scripts over the years that grab specifics and help them narrow down where problems are.

No, I cannot post mine.

Many scripts can be found with a simple Google search.
