Please help to fix this issue.

Azure Alerts enable you to proactively monitor and manage your Azure resources by notifying you when certain conditions are met. These conditions are specified using alert rules, and when triggered, alerts can initiate actions to address or investigate issues.

• Navigate to your Service Bus namespace in the Azure portal. Under "Monitoring" > "Alerts", create a new alert rule. Select appropriate metrics like "Active Messages", "Dead-lettered Messages", or "Server Errors".

• For the selected one, choose Split by dimensions and select Dimension Name as EntityName and Dimension values as AzureServiceBusTopicName.

• Select the operator used to compare the metric value against the threshold and enter a threshold number.

• If required, select action groups or create an action group.

• If required, select action groups or create an action group. I have selected the action group "mail" in the Actions tab. Ensure to fill in the Alert rule details in the details tab, such as:

• The severity of the alert when the rule's condition is met,

• Choose a name to identify this alert rule, and

• Add a description for this alert rule .
