Once Real User Monitoring (RUM) is enabled for your organization, you can create a RUM monitor to alert you when a specific RUM event type exceeds a predefined threshold over a given period of time.
To create a RUM monitor in Datadog, first navigate to Monitors > New Monitor > Real User Monitoring.
As you expand your search filters, the graph above the search bar updates.
Construct a search query using the same logic as a RUM Explorer search.
Choose to monitor over a RUM event count, facet, or measure.

).Group RUM events by multiple dimensions (optional). All RUM events matching the query are aggregated into groups based on the value of up to four facets.
Configure the alerting grouping strategy (optional).

and you select Simple-Alert, you get one alert when one or multiple groups values breach the threshold. You may use this strategy to reduce notification noise.@browser.name
to receive a separate alert for each browser when the number of errors is high.Add multiple queries and apply formulas and functions (optional):

.To receive a notification when an application has stopped sending RUM events, set the condition to below 1
. This notifies when no RUM events match the monitor query in a given time frame across all aggregate groups.
When splitting the monitor by any dimension (tag or facet) and using a below
condition, the alert is triggered if and only if there are RUM events for a given group, and the count is below the threshold—or if there are no RUM events for all of the groups.
For example, this monitor triggers if and only if there are no RUM events for all applications:
And this monitor triggers if there are no logs for the application Shop.ist
