Application Insights: Metric Alerts set to 1 min frequency sometimes trigger false alert due to delay in data upload
Metric alerts are setup to notify when the activity is either unexpectedly low or unexpectedly high. Following the steps in the documentation, 1 minute for aggregation and 1 minute for frequency is set.
However, emails are send periodically saying the request count went below the designated threshold. Also, the graph does not show the dip reported below the threshold. The periodic false alert is due to the delay in data that do not get uploaded. Either update the document the true smallest recommended frequency or fix the performance of the periodic delay that is triggering the false alerts.
