What you need to know
DSE recommends documenting the decision’s required freshness and the specific queue before selecting a metric.
Potentially affected
This applies when an operations team is choosing a backlog observation for Azure Queue Storage and needs to decide whether a worker workload should be adjusted.

Source facts
Microsoft describes QueueMessageCount as a storage-account-wide queue message metric refreshed daily. For dynamic workload adjustments, the guide recommends querying each queue’s approximate message count. Microsoft Learn

DSE recommendation
DSE recommends documenting the decision’s required freshness and the specific queue before selecting a metric. Keep account-level reporting distinct from the per-queue observations used for responsive action. Record that the direct count is approximate and choose an observation interval appropriate to the workload. Ask the application owner to define a bounded response and the conditions for stopping or reversing it, rather than making an unbounded change from a single count.
Verification
Capture the observation time, queue identity, and approximate count alongside worker activity during a controlled test. Compare the proposed action with the workload’s agreed completion and stability criteria. Recheck after the action and retain the resulting evidence. Do not describe a daily aggregate as the instantaneous backlog of a particular queue or report improved processing without observing the workload result.
