Alert to see if messages are stuck in Servicebus Queue during a particular time in a day

Question

I have a queue in my service bus and every day at 9am to 10 am I get 1000 messages. I have a function app which picks up the messages and processes them. So ideally after 11 am active messages count in the queue should be 0. But sometimes my function app stop processing them, and it get stuck forever. Is there a way to alert me to say the messages are not getting processed from the queue.

I tried the alerts in service bus, but it seems it monitor for the entire day... is there a way to say only for a particular time to monitor 9 to 11 am every day?

Hi there,

You can't configre the logic by using Azure metrics purely. To achieve the scenario, you need to ingest the metrics data to Log Analytics first via diagnostics settings.
In the Log Analytics workspace, you will be able to correlate the data as required

Here is a link that shows how to do it using Azure CLI or Powershell https://learn.microsoft.com/en-us/azure/service-bus-messaging/message-counters . You could create a process that runs every couple of minutes during the period you are concerned about and sends you an alert.
