By default, the Manager determines alert capacity based on the pre-defined limit of 10,000,000 alerts. When varying percentages of this capacity is reached, a system fault is raised alerting you of the reached threshold. System faults are raised at 80-90%, 90-95%, 95-99% of the alert capacity to let you know that you are approaching the 10,000,000 alert threshold. You can view and configure this threshold by opening the Manager's System Configuration interface, selecting the Manager tab's Maintenance menu. This is seen in configuration steps as Manager → <Admin Domain Name> → Maintenance → Database Pruning → Alert Pruning.
Note
This threshold is purely for capacity planning purposes and does not re-configure the size of your database.
