The hierarchy diagram displays your sites in a topology map. In this view, you can select a site and view a status message summary from that site, drill through to view status messages, and access the Properties dialog box of the sites.

Additionally, you can pause the mouse pointer on a site or replication link between sites to view high-level status for that object. Because replication link status does not replicate globally, in a hierarchy with multiple primary sites, you must connect your Configuration Manager console to the central administration site to view the replication link details between all sites.

The following options modify the hierarchy diagram:

• Groups: You can configure the number of primary sites and secondary sites that trigger a change in the hierarchy diagram display that combines the sites into a single object. When sites are combined into a single object, you see the total number of sites and a high-level rollup of status messages and site status. Group configurations do not affect the geographical view.
  
  
• Favorite sites: You can specify individual sites to be a favorite site. A star icon identifies a favorite site in the hierarchy diagram. Favorite sites are not combined with others sites when you used groups and always are displayed individually.
  
  

The geographical view displays the location of each site on a geographical map. Only sites that you configure with a location are displayed. When you select a site in this view, replication links to parent or child sites are shown. Unlike the hierarchy diagram view, you cannot display site status message or replication link details in this view.

Note
To use the geographical view, the computer to which your Configuration Manager console connects must have Internet Explorer installed and be able to access Bing Maps by using the HTTP protocol.

The following option modifies the geographical view.

• Site Location: You can specify a geographical location for each site. You can specify the location as a street address, a place name such as the name of a city, or by latitude and longitude coordinates. For example, to use the latitude and longitude of Redmond Washington, you would specify N 47 40 26.3572 W 122 7 17.4432 as the location of the site. You do not need to specify the symbols for the degree, minutes or seconds of longitude or latitude. Configuration Manager uses Bing Maps to display the location on the geographical view. This provides you the option to view your hierarchy in relation to a geographical location, which can provide insight into regional issues that might affect specific sites or intersite replication.
  
  When you specify a location, you can use the Location box to search for a specific site in your hierarchy. With the site selected, enter the location as a city name or street address in the Location column. Configuration Manager uses Bing Maps to resolve the location.
  
  

Database replication between sites involves the replication of several sets of information, called replication groups. Each replication group replicates with different replication priorities. By default, the data contained in a replication group and the frequency of replication cannot be modified.

When a replication link is active, and does not have a status of failed or degraded, all replication groups replicate in a timely manner. When one or more replication groups fail to complete replication in the expected period of time, the link displays as degraded. Degraded links can still function, but you should monitor them to ensure that they return to active status, or investigate them to ensure that additional degradation or replication failures do not occur.

With Configuration Manager SP1, for each replication link you can specify the number of times that an unsuccessfully replicated replication group retries to replicate before the status of the link is set to degraded or failed. Even if all but one replication group replicate successfully, the status of the link is set to degraded or failed because the one replication group fails to complete replication in the specified number of attempts. For information about replication thresholds, see the Plan for Database Replication Thresholds section in the Planning for Communications in Configuration Manager topic.

Use the information in following table to understand the status of replication links that might require further investigation.

While a parent site is in the process of upgrading to a new service pack and you view the link status from the child site, the link status displays as active. After the upgrade, until the child site is also at the same service pack as the parent site, the link status displays as active when viewed from the parent site, and as being configured when viewed from the child site.

You can use the Database Replication node in the Monitoring workspace to view the status of replication for a replication link, and view details about the site database at each site on the replication link. With Configuration Manager SP1, you can also view details about replication groups. To view details, select a replication link, and then select the appropriate tab for the replication status you want to view. The following table provides details about the different tabs for replication status.

Tab	Details
Summary	View high level information about the replication of site data and global data between the two sites on a link. You can also click View reports for historical traffic data to view a report that shows details about the network bandwidth used by replication across the replication link.
Parent Site	For the parent site on a replication link, view details about the database, which include: Firewall ports for the SQL Server Free disk space Database file locations Certificates
Child Site	For the child site on a replication link, view details about the database, which include: Firewall ports for the SQL Server Free disk space Database file locations Certificates
Initialization Detail	For Configuration Manager SP1 only: View the initialization status for replication groups that replicate across the replication link. This information can help you identify when initialization of replication data is in progress or has failed. Additionally, You can use this information to identify when a site might be in interoperability mode. Interoperability mode occurs when the child site does not run the same version of Configuration Manager as the parent site.
Replication Detail	For Configuration Manager SP1 only: View the replication status for each replication group that replicates across the link. Use this information to help identify problems or delays for the replication of specific data, and to help determine the appropriate database replication thresholds for this link. For information about database replication thresholds, see the Plan for Database Replication Thresholds section in the Planning for Communications in Configuration Manager topic. Tip Replication groups for site data are sent only from the child site to the parent site. Replication groups for global data replicate in both directions.

The following items are prerequisites to use the Replication Link Analyzer:

• The account that you use to run the Replication Link Analyzer must have local administrator rights on each computer that is involved in the replication link. The account does not require a specific role-based administration security role. Therefore, an administrative user with access to the Database Replication node can run the tool in the Configuration Manager console, or a system administrator with sufficient rights to each computer can run the tool at a command prompt.
  
  
• The account that you use to run the Replication Link Analyzer must have sysadmin rights on each SQL Server database that is involved in the replication link.
  
  

1. In the Configuration Manager console, click Monitoring.

2. In the Monitoring workspace, click Site Hierarchy to open the Hierarchy Diagram view.

3. Briefly pause the mouse pointer on the line between the two sites to view the status of global and site data replication for these sites.

1. In the Configuration Manager console, click Monitoring.

2. In the Monitoring workspace, click Database Replication, and then select the replication link for the link that you want to monitor. Then, in the workspace, select the appropriate tab to view different details about the replication status for that link.
