You can set up real-time notifications for new alerts or for already existing alerts.
For both cases, you need to go to Smart Alerts and, depending on the case, click on New Alert or Edit Alert.
For both new or existing alerts, a pop-up similar with the one below will appear.
Go to Frequency and select real-time Real-time. Once you're done, click Save.
Real-time frequency is available for all types of alerts, except RSS Feed.
In case Real Time Monitoring was not set up for your project, it will be turned to ON automatically, once you create a real-time alert.
