# Describing Amazon DocumentDB instances
<a name="db-instance-view-details"></a>

You can use either the Amazon DocumentDB Management Console or the AWS CLI to see details such as connection endpoints, security groups VPCs, certificate authority, and parameter groups pertaining to your Amazon DocumentDB instances.

------
#### [ Using the AWS Management Console ]

To view the details of your instances using the AWS Management Console, follow the steps below.

1. Sign in to the AWS Management Console, and open the Amazon DocumentDB console at [https://console.aws.amazon.com/docdb](https://console.aws.amazon.com/docdb).

1. In the navigation pane, choose **Clusters **.
**Tip**  
If you don't see the navigation pane on the left side of your screen, choose the menu icon (![\[Hamburger menu icon with three horizontal lines.\]](http://docs.aws.amazon.com/documentdb/latest/developerguide/images/docdb-menu-icon.png)) in the upper-left corner of the page.

1. In the Clusters navigation box, you’ll see the column **Cluster Identifier**. Your instances are listed under clusters, similar to the screenshot below.  
![\[Clusters table showing list of clusters under Cluster identifier column, with instances nested inside clusters.\]](http://docs.aws.amazon.com/documentdb/latest/developerguide/images/choose-clusters.png)

1. In the list of instances, choose the name of the instance that you want to see its details. The information about the instance is organized into the following groupings:
   + **Summary**—General information about the instance, including the engine version, class, status, and any pending maintenance.
   + **Connectivity & Security** —The **Connect** section lists the connection endpoints to connect to this instance with the mongo shell or with an application. The **Security Groups** section lists the security groups associated with this instance and their VPC ID and descriptions.
   + **Configuration**—The **Details** section lists the configurations and status of the instance, including the instance's Amazon Resource Name (ARN), endpoint, role, class, and certificate authority. It also lists the instance's security and network settings, and backup information. The **Cluster details** section lists the details of the cluster that this instance belongs to. The **Cluster instances** section lists all the instances that belong to your cluster with each instance's role and cluster parameter group status.
**Note**  
You can modify the cluster associated with your instance by selecting **Modify** next to the **Cluster details** header. For more information, see [Modifying an Amazon DocumentDB cluster](db-cluster-modify.md). 
   + **Monitoring**—The CloudWatch Logs metrics for this instance. For more information, see [Monitoring Amazon DocumentDB with CloudWatch](cloud_watch.md). 
   + **Events & tags** —The **Recent events** section lists the recent events for this instance. Amazon DocumentDB keeps a record of events that relate to your clusters, instances, snapshots, security groups, and cluster parameter groups. This information includes the date, time, and message associated with each event. The **Tags** section lists the tags attached to this cluster. For more information, see [Tagging Amazon DocumentDB resources](tagging.md).

#### [ Using the AWS CLI ]

To view the details of your Amazon DocumentDB instances using the AWS CLI, use the `describe-db-clusters` command as shown in the examples below. For more information, see [https://docs.aws.amazon.com/documentdb/latest/developerguide/API_DescribeDBInstances.html](https://docs.aws.amazon.com/documentdb/latest/developerguide/API_DescribeDBInstances.html) in the *Amazon DocumentDB Resource Management API Reference*. 

**Note**  
For certain management features such as cluster and instance lifecycle management, Amazon DocumentDB leverages operational technology that is shared with Amazon RDS. The `filterName=engine,Values=docdb` filter parameter returns only Amazon DocumentDB clusters.

1. **List all Amazon DocumentDB instances.**

   The following AWS CLI code lists the details for all Amazon DocumentDB instances in a region.

   For Linux, macOS, or Unix:

   ```
   aws docdb describe-db-instances \
       --filter Name=engine,Values=docdb
   ```

   For Windows:

   ```
   aws docdb describe-db-instances \
       --filter Name=engine,Values=docdb
   ```

1. **List all details for a specified Amazon DocumentDB instance**

   The following code lists the details for `sample-cluster-instance`. Including the `--db-instance-identifier` parameter with the name of an instance restricts the output to information on that particular instance.

   For Linux, macOS, or Unix:

   ```
   aws docdb describe-db-instances \
       --db-instance-identifier sample-cluster-instance
   ```

   For Windows:

   ```
   aws docdb describe-db-instances \
       --db-instance-identifier sample-cluster-instance
   ```

   Output from this operation looks like the following.

   ```
