Trigger an laert when no data received for a period of time?

[Jerome22]

Hi,

how I can setup an alert when there is no messages received in an event stream?

and doing this based on a value of a property.

for example, I have a "region" property, and I want to trigger the alert if I have not received an event in the last 2hours per region.

so if the East region has not sent any event for the past 2hours, trigger the alert for this region. while I can have received events from others.

if it's not possible per region, can I receive the alert if no new event appeared in the past 2hours?

I tried a "count" aggregation and the trigger is if the count =0 for 2hours

but it's not working.

any guide? thanks.

That is now available in Data Activator. See the last option.
