Description:
When an agent is first installed and picked up by Monitor, it creates the name that shows up in the dashboard as the displayname or server:3306 by default.

When the displayname and/or hostname of the agent machine is changed and the agent is restarted, it does not get changed on the Monitor.

The displayname will change when the agent is stopped, removed from Monitor and then re-detected.

How to repeat:
Change the displayname and restart the agent.

Suggested fix:
The displayname should update when the agent is restarted.

I've added notes with discussion with Leith to the hostname and server rename sections of the docs to show which change has precedence.
