RabbitMQ Pubish vs Delivered Queue messages rate

mn_24 — Mon, 19 Oct 2026 06:32:08 GMT

Hi,

We'd like to have an alerting metric for publish vs delivered messages and in Data Explorer is fine but when we try to configure it in Anomaly Detection metrics I see this message:

We are using Managed and not SaaS.

Your pictures are not readable well, but i used my sherlock holmes skills to suggest you to remove ":fold(avg)" from your selector, because anomaly detection requires multiple values instead of single.

Hi,

yes, indeed but the expected result is when I am using :fold(avg). Is there a way of how to workaround this requirement for multiple values? 🙂

Fold transformation produces single value for specific timeframe. What is your required timeframe for evaluation in anomaly detection?

10min

Then try :rollup(avg, 10m) transformation.
