Report-Based alerts
When a tabular report has been populated with data, you can set an alert to notify you. For example, you can save a Job Summary Report for Failed Events and then configure an alert for this report. The Portal will check for a report that contains data according to the schedule you select. You can configure alerting for any report that contains a single table. A report must be saved before you can set an alert.
See Setting Up Alerts for Tabular Reports.
For convenience, your reports with an alert configured are displayed in this section of the Alerts tab. These report-based alerts are not system wide and only belong to the logged in user.
