 ## Monitoring data collected from Azure Cosmos DB
 
 Azure Cosmos DB collects the same kinds of monitoring data as other Azure resources which are described in [Monitoring data from Azure resources](../azure-monitor/insights/monitor-azure-resource.md#monitoring-data). See [Azure Cosmos DB monitoring data reference](monitor-cosmos-db-reference.md) for a detailed reference of the logs and metrics created by Azure Cosmos DB.

+# How to monitor the server-side latency for operations in an Azure Cosmos DB container or account
+
+Azure Monitor for Azure Cosmos DB provides a metrics view to monitor your account and create dashboards. The Azure Cosmos DB metrics are collected by default, this feature does not require you to enable or configure anything explicitly.
+The server-side latency metric is used to view the server-side latency of an operation. For example, if you see unusually large latency for point operations such as:
+
+* A get or set operation with partition key and id in direct mode
+* A read or write operation or
+* A query
+
+You can look up the diagnostic log to see the size of data returned. If you see a sustained high latency for query operations, you can look up the diagnostic log for size of data returned, [throughput or RU/s](cosmosdb-monitor-resource-logs.md#diagnostic-queries) used, or the number of such operations in a given period. This way, you can debug the server-side latency issues.
+
+## View server-side latency metric
+
+1. Sign in to the [Azure portal](https://portal.azure.com/).
+
+1. Select **Monitor** from the left-hand navigation bar and select **Metrics**.
+
+  ![Metrics pane in Azure Monitor](./media/monitor-server-side-latency/monitor-metrics-blade.png)
+
+1. From the **Metrics** pane > **Select a resource** > choose the required **subscription**, and **resource group**. For the **Resource type**, select **Azure Cosmos DB accounts**, choose one of your existing Azure Cosmos accounts, and select **Apply**.
+   
+   ![Choose a Cosmos DB account to view metrics](./media/monitor-server-side-latency/select-cosmosdb-account.png)
+
+1. Next select the **Server Side Latency**  metric from the list of available metrics. To learn in detail about all the available metrics in this list, see the [Metrics by category](monitor-cosmos-db-reference.md) article. In this example, let's select **Server Side Latency** and **Avg** as the aggregation value. In addition to these details, you can also select the **Time range** and **Time granularity** of the metrics. At max, you can view metrics for the past 30 days.  After you apply the filter, a chart is displayed based on your filter. You can see the average number of request units consumed per minute for the selected period.  
+
+   ![Choose the Server Side Latency metric from the Azure portal](./media/monitor-server-side-latency/serverside-latency-metric.png)
+
+### Filters for server-side latency
+
+You can also filter metrics and the chart displayed by a specific **CollectionName**, **ConnectionMode**, **DatabaseName**, **OperationType**, **Region**, and **PublicAPIType**. 
+
+To filter the metrics, select **Add filter** and choose the required property such as **PublicAPIType** and select the value **sql**. Add another filter for **OperationType**. The graph then displays the server-side latency for different operations during the selected period. The operations executed via Stored procedure are not logged so they are not available under the OperationType metric.
+
+The **Server Side Latency** metrics for each operation are displayed as shown in the following image:
+
+![Filters for server-side latency metrics](./media/monitor-server-side-latency/serversidelatency.png)
+
+You can also group the metrics by using the **Apply splitting** option.
