Contact your client manager or enter a support request if you would like to receive automatic notifications on pre-defined monitoring events. We now offer monitoring on the following metrics:
* Disk I/O
* Disk usage
* Inbound and outbound bandwidth
* A process list ordered by CPU or memory usage
Monitoring is offered by Digital Ocean on all droplets. If your account is setup through a Team Account, then you have direct access to monitoring in your control panel. See https://www.digitalocean.com/company/blog/introducing-monitoring/ for more details.
