Hello, I would like to know how to filter out resources from cloudwatch that no longer exist - or rather only retrieve resources which return any values for given interval like “last 3h”. To give an example: Let’s say I create a variable query for: “dimension\_values($region,AWS/Kinesis,IncomingBytes,StreamName)” And our workload creates and destroys Kinesis Streams on a daily basis (don’t ask why). How can I make this query to return only valid Kinesis streams from this metric - instead of returning each and every kinesis stream that was ever created matching patter… I thought Grafana will be smart enough to filter out values of not existing resources, but its not. Help ? ---
