Hello All,
I am stupid stuck with setting up an alert when no data received after a couple of minutes.
I have looked online and can’t find anything that helps.
It is emailing me, but not when no data and seems to be doing it for a past event every day?
Hi Mark! 
Can we see the error message for the Error alert in the screenshot?
Hi! You need to either use an instant query or add a Reduce expression in order to reduce the time series data (individual data points each containing a timestamp and a value) into a single value. You can find the docs on this here.
Or here.
Got it sorted. Thank you all very much. Much appreciated!
