# Source servers
<a name="wave-source-servers"></a>

The **Source servers** tab shows migration metrics aggregating statuses as well as a list of all the wave's associated applications. 

The source server migration metrics provide an aggregated overview of the wave's associated servers on three topics: **Alerts**, **Data replication status**, and **Migration status**.

# Review alerts on source servers in a wave
<a name="wave-source-server-migration-metrics-alerts"></a>

The source server **Alerts** metric provides an aggregated overview of the alerts related to the wave's associated servers. You can look up an individual source server **Alerts** status at the **Source servers** table at the bottom of the page.

+ A healthy server for which a test or cutover instance has not been launched will display a **Healthy** status. 
+ A healthy server for which a test or cutover instance has been launched will display a **Healthy** status. 
+ A server that is experiencing a temporary issue such as a lag or backlog will display a **Lagging** status. 
+ A server that is experiencing significant issues, such as a stall, will display a **Stalled** status. 

# Review data replication status of the servers in a wave
<a name="wave-source-server-migration-metrics-drs"></a>

The source server **Data replication status** metric provides an aggregated overview of the data replication status of the wave's associated servers. You can look up an individual source server **Data replication status** status at the **Source servers** table at the bottom of the page. 

![\[Pie chart showing data replication status: 66.7% Healthy (2 servers), 33.3% Initial sync (1 server).\]](http://docs.aws.amazon.com/mgn/latest/ug/images/app-8.png)


Source server's **Data replication status** can have one of the following values: 
+  **Transferring snapshot** 
+  **Initial sync** 
+  **Finalizing sync** 
+  **Lagging** 
+  **Healthy** 
+  **Stalled** 
+  **Rescanning** 
+  **Not started** 
+  **Initiating** 
+  **Creating snapshot** 
+  **Paused** 
+  **Disconnected** 

# Review the migration lifecycle for the servers in a wave
<a name="wave-source-server-migration-metrics-migration"></a>

The source server's **Migration lifecycle** metric provides an aggregated overview of the migration lifecycle of the wave's associated servers . You can look up an individual source server's **Migration lifecycle** status at the **Source servers** table at the bottom of the page. 

![\[Pie chart showing migration lifecycle status: equal distribution among three server states.\]](http://docs.aws.amazon.com/mgn/latest/ug/images/app-9.png)


The source server's **Migration lifecycle** can have one of the following values: 
+  **Stopped** 
+  **Not ready** 
+  **Ready for testing** 
+  **Test in progress** 
+  **Ready for cutover** 
+  **Cutover in progress** 
+  **Cutover complete** 
+  **Disconnected** 
+  **Discovered** 

# Review the source servers in a wave
<a name="wave-source-servers-table"></a>

The **Source servers** table lists all the servers that are associated with the wave. 

You can perform batch operations on all the servers via the wave **Actions** menu at the top of the page. You can perform an operation on a single server from its own **Server details** page, by clicking on the server **Source server name**. 

# Review tags assigned to a wave
<a name="wave-cirrus_tags"></a>

The **Tags** section shows any tags that have been assigned to the wave. A tag is a label that you assign to an AWS resource. Each tag consists of a key and an optional value. You can use tags to search and filter your resources or track your AWS costs. Learn more about AWS tags in [this Amazon EC2 article](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Using_Tags.html).
