There is no pre-complied list, you can take a look at the System Profile under Measures, where you find all predefined measures:
You can add a lot more custom metrics though, e.g. custom JMX metrics. Take a look at the create measure dialog to check the possibilities.
The only way I found in the documentation to get a list is to use a existing system profile and make an export, it is described at the bottom under List of measurements with description.
The output would look like this.
