What type of alerting can monitors in Datadog offer?

Monitors in Datadog are designed to provide alerts based on predefined conditions derived from various data sources, including metrics and logs. This means that users can set specific thresholds or conditions that, when met, trigger notifications or alerts. This functionality is integral for maintaining the health of systems and applications, as it allows teams to proactively address issues before they impact users or operations.

By leveraging metrics or logs, monitors enable users to gain insights into performance, availability, and other critical parameters of their systems. This automated alerting mechanism is essential for effective monitoring and incident response in complex environments.

The other choices do not fully encompass the capabilities of Datadog monitors. Basic reminders for server resets are not a primary function of monitors. While alerts for performance issues may fall under the broader category of alerts based on metrics, Datadog's capabilities extend well beyond just performance, encompassing a wide array of functionalities including error rates, system health, and more by analyzing logs and other data. Lastly, alerts that rely solely on user inputs would be insufficient as they would lack the automated monitoring aspect that is fundamental to Datadog's alerting system.
