In Azure portal, click on Monitor. The Monitor blade consolidates all your monitoring settings and data in one view.

Click Alerts then click + New alert rule.

Click Select, in the context pane that loads, select a target resource that you want to alert on. My target resource is Storage account.

Click Done

Once you have selected a target resource, click on Add condition.

You will see a list of signals supported for the resource, select the metric you want to create an alert on.

In my case I will select Egress

You will see a chart for the metric for the last 6 hours. Define the alert parameters; Condition Type, Frequency, Operator and Threshold or Sensitivity, this will determine the logic which the metric alert rule will evaluate.

If you are using a static threshold, the metric chart can help determine what might be a reasonable threshold. If you are using a Dynamic Thresholds, the metric chart will display the calculated thresholds based on recent data.
