Alert Time Intervals

The Atera agent, the backbone of the Atera monitoring system, monitors the availability, performance and health of the workstation\server, at regular intervals and securely communicates back to the cloud. The reporting intervals are based on extensive big data analysis, ensuring optimal notification timing. This article outlines the time intervals used by Atera when monitoring different types of system events that trigger Alerts. The table below displays the most common Atera alert types, and the time intervals within which you can expect to receive those alerts.
