DigitalOcean Uptime is a monitoring service that checks the health of any URL or IP address. You can use it to monitor the latency, uptime, and SSL certificate of any website or host, and can choose to receive alerts via email or Slack when your site is down, experiencing high latency, or has an SSL certificate that’s about to expire.

The DigitalOcean API lets you manage DigitalOcean resources programmatically using conventional HTTP requests. All the functionality available in the DigitalOcean Control Panel is also available through the API.
doctl is a command-line interface for the DigitalOcean API and supports many of the same actions.
