DQL query in Notebook returned the average value but throwing error when trying to setup Anomaly detection .

How should i configure alerting based on "avg(percentage5xx)" ?

I think it might be because when you use summarize command, the timeseries data get 'converted' back to tabular data.

Maybe can try to achieve what you want by 1. Without using the summarize command or 2. Add a last line in your DQL that would be using makeTimeseries command.
