In a pervious project I have managed to setup a Alert rule that looks at poison queue message count and alerts using a webhook into slack when something is in the queue (once per day).

I was trying to find where this exists in Azure as it looks like things have moved around. If this is not a feature provided by azure could you give guidance on what's the best route in implementing something similar.

Thanks

I was trying to find where this exists in Azure as it looks like things have moved around. If this is not a feature provided by azure could you give guidance on what's the best route in implementing something similar.

As far as I know, currently there is no a feature provided by azure to send the a alert rule to check the poison queue count.

You need write you own logic to achieve this requirement.

I suggest you could considerusing webjob/azure function timer trigger or queue trigger.

If you want to check the poison count every 5 minutes(for example), you could choose timer trigger.

Then in the timer trigger method, you could use ApproximateMessageCount method to get the queue messages' count.

At last, you could use sendgrid to send the notification email to special account.

Codes:

        //get the storage account from the connection string
        CloudStorageAccount storageAccount = CloudStorageAccount.Parse(CloudConfigurationManager.GetSetting("StorageConnectionString"));

        //instantiate the client
        CloudQueueClient queueClient = storageAccount.CreateCloudQueueClient();

        CloudQueue q = queueClient.GetQueueReference("queue-poison");
        q.FetchAttributes();
        var qCnt = q.ApproximateMessageCount;

If you want to get the count when the new queue message has added into the poison queue. You could choose queue trigger. The codes is as same as the timer trigger, just change the parameters.
