Alert definitions and thresholds

As a Monitor administrator, you can configure the thresholds that are used to trigger alerts.

The following list describes the alerts and their default thresholds.

Because each synchronization system has different behaviors and constraints, the defaults may be inappropriate for your environment. You should review each alert threshold and adjust them as necessary.
