To change some of the basic options for your Linode, click the Dashboard link.
In the sub menu – click the Settings link.
Here you can change your Automatically Generated Linode Label.
Rename the server to: MyLinode.
You can also enable or disable the shutdown watchdog. This automatically restarts your Linode if it unexpectedly powers off. It's a good idea to keep this enabled to ensure your server is not down for long periods of time.
Under the Email Alerts heading you can customize the types of alerts you receive. For example, by default you will receive an email alert if 90% of your CPU usage has been utilized.
