Microsoft Azure: How to use waagent (Microsoft Azure Linux Agent)

After installation waagent on my ubunu server, i tried to use this tool.
First guess was to read the manpages, but there is no entry for waagent:

root@ubuntuserver:~# man waagent
No manual entry for waagent
See 'man 7 undocumented' for help when manual pages are not available.

So for documentation you have to visit the Microsoft Azure portal:
https://docs.microsoft.com/en-us/azure/virtual-machines/extensions/agent-linux

Here are some commands i tried:

root@ubuntuserver:~# waagent -show-configuration
