The service provides monitoring of websites and other online resources for continuous uptime, with alerts in case a resource becomes unresponsive. It allows creation of "probes" that interact with specified URLs at preset intervals and report back response status to the service. Probes set criteria for notification, including contact method and address, conditions to trigger notification, frequency of messages, etc.
API methods support basic operations for creating, reading, updating, and deleting monitoring rules (CRUD operations) including the resources monitored and responses to status detected. Methods also support retrieving and reporting on data such as uptime statistics and history of alerts.
