DigitalOcean Uptime is a monitoring service that checks the health of any URL or IP address. Use Uptime to monitor the latency, uptime, and SSL certificates of any website or host, and receive email or Slack alerts at thresholds you choose.
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.
