When you have critical applications and business processes relying on Azure resources, you want to monitor those resources for their availability, performance, and operation. This article describes the monitoring data generated by Azure Cosmos databases and how you can use the features of Azure Monitor to analyze and alert on this data.

The account level metrics available in the portal, such as account storage usage and total requests, are not available via the SQL APIs. However, you can retrieve usage data at the collection level by using the SQL APIs. To retrieve collection level data, do the following:
194131
195132
* To use the REST API, [perform a GET on the collection](https://msdn.microsoft.com/library/mt489073.aspx). The quota and usage information for the collection is returned in the x-ms-resource-quota and x-ms-resource-usage headers in the response.
133+
196134
* To use the .NET SDK, use the [DocumentClient.ReadDocumentCollectionAsync](https://msdn.microsoft.com/library/microsoft.azure.documents.client.documentclient.readdocumentcollectionasync.aspx) method, which returns a [ResourceResponse](https://msdn.microsoft.com/library/dn799209.aspx) that contains a number of usage properties such as **CollectionSizeUsage**, **DatabaseUsage**, **DocumentUsage**, and more.

To access additional metrics, use the [Azure Monitor SDK](https://www.nuget.org/packages/Microsoft.Azure.Insights). Available metric definitions can be retrieved by calling:
