From Curity 5.2 there is a new Alarms subsystem that provides the ability to monitor critical parts of the deployment, and that creates alerts if something is misbehaving.
When an alarm state changes in the Curity Identity Server, all configured Alarm Handlers are notified. An incident management system can use this to create reports and workflows for the operators that need to take action.
The Curity Identity Server comes with a fully supported integration with PagerDuty. It is easily configured and works out of the box.
All alarm state changes are posted to PagerDuty using their Events API v2 and can used to trigger incidents and workflows in the PagerDuty control panel.
For details on how to configure this in the Curity Identity Server and in PagerDuty, see the Curity Reference Documentation for the PagerDuty alarm handler.
