For example, you can view and monitor the [server side latency metric](monitor-server-side-latency.md), [normalized request unit usage metric](monitor-normalized-request-units.md), etc.
 
    * **Insights:** This pane provides a customized monitoring experience for Azure Cosmos DB. Insights use the same metrics and logs that are collected in Azure Monitor and show an aggregated view for your account.

    * **Latency**. This tab shows the read and write latency observed by Azure Cosmos DB in the region where your account is operating. You can visualize latency across regions for a geo-replicated account. You can also view server-side latency by different operations. This metric doesn't represent the end-to-end request latency.

 ## Compare data size against index size
 
-In Azure Cosmos DB, the total consumed storage is the combination of both the data size and dndex size. Typically, the index size is a fraction of the data size. To learn more, see the [Index size](index-policy.md#index-size) article. In the Metrics pane in the [Azure portal](https://portal.azure.com), the Storage tab showcases the breakdown of storage consumption based on data and index.
