I have a metric from AWS for the number of messages visible in a SQS queue, which gets computed every 5 minutes.  2023-08-02 11:50:00    13.3 2023-08-02 11:55:00    0.0 2023-08-02 12:00:00    33.8 2023-08-02 12:05:00    0.0 This means that there were 13 messages in the queue, and 5 minutes later they were gone (processed). Then there were 33, then they were gone (processed) If messages do not get processed, I'd expect this number to continue to grow and not decrease.  I need to set up an alert when that happens. Is there some way to alert when a value grows, say, over 5 rows?  Or, is there a way to compare a value to itself at different points in time?    ... View more
