 # Troubleshooting problems in Azure Monitor metric alerts 
 
@@ -301,6 +301,86 @@ Consider one of the following options:
 * If your data has weekly seasonality, but not enough history is available for the metric, the calculated thresholds can result in having broad upper and lower bounds. For example, the calculation can treat weekdays and weekends in the same way, and build wide borders that don't always fit the data. This should resolve itself once enough metric history is available, at which point the correct seasonality will be detected and the calculated thresholds will update accordingly.
 
 
+## When configuring an alert rule's condition, why is Dynamic threshold disabled?
+While dynamic thresholds are supported for the vast majority of metrics, there are some metrics that can't use dynamic thresholds.

+The table below lists the metrics that aren't supported by dynamic thresholds.
