When an Enterprise Distributed Application Service (EDAS) application triggers an alert, the Alert page is your starting point for investigation. From this page, you can review what happened, identify the root cause, and take action to resolve the issue.
The Alert page supports the following tasks:
Filter alerts by name, status, severity, handler, or time range to locate specific incidents.
View alert details, related events, and notification history.
Claim, reassign, or resolve alerts directly from the console.

Handle alerts
EDAS tracks each alert through three states:
| Status | Description |
|---|---|
| To Be Claimed | The alert is new and has not been claimed. |
| Processing | A user has claimed the alert and is investigating. |
| Resolved | The processing of the alert has ended. |
To Be Claimed is the initial state set by the system when an alert fires. The other two states are set by users through manual actions.
