+**What does a dashed line in an Azure Metric chart indicate?**
+
+Some Azure metrics charts, such as the ones that display availability and latency data, use a dashed line to indicate that there's a missing value (also known as null value) between two known time grain data points. For example, if in the time selector you picked `1 minute` time granularity, but the metric was reported at 07:26, 07:27, 07:29, and 07:30, then a dashed line connects 07:27 and 07:29 because there's a minute gap between those two data points. A solid line connects all other data points. The dashed line drops down to zero when the metric uses count and sum aggregation. For the avg, min or max aggregations, a dashed line connects the two nearest known data points. Also, when the data is missing on the rightmost or leftmost side of the chart, the dashed line expands to the direction of the missing data point.

+**How do I track availability of my storage account?**
+
+You can configure a resource health alert based on the [Azure Resource Health](/azure/service-health/resource-health-overview) service to track the availability of your storage account. If there are no transactions on the account, then the alert reports based on the health of the Storage cluster where your storage account is located.
