T-SQL to find Navigation path in CMS

In large enterprises there will be huge number of SQL servers which will be registered within a Central Management Server (CMS) and times it may become difficult to find out where the server is registered atleast for new team members in the Huge pile of servers and folder structure. This query give you the path where the specified servers is registered within the CMS.

DECLARE @ServerName nvarchar(50)
SET @ServerName='SQL01';

WITH CMSCTE
AS
(
--Anchor
SELECT server_group_id, name, description, parent_id, 1 AS [Level], CAST((name) AS VARCHAR(MAX)) AS CMSPath
FROM msdb.dbo.sysmanagement_shared_server_groups AS A
WHERE parent_id IS NULL
UNION ALL
--Recursive Member
SELECT B.server_group_id, B.name, B.description, B.parent_id, C.[level] + 1 AS [Level], CAST((C.CMSPath + '->' + B.Name) AS VARCHAR(MAX)) AS CMSPath
FROM msdb.dbo.sysmanagement_shared_server_groups AS B
JOIN CMSCTE AS C 
ON B.parent_id = C.server_group_id  
)

SELECT TOP 1 CMSPath AS 'Path in CMS' , B.name as 'Server Name', B.description AS 'Server Description', A.name AS 'Group Name', A.description AS 'Group Description'
FROM CMSCTE AS A
INNER JOIN msdb.dbo.sysmanagement_shared_registered_servers AS B
ON A.server_group_id=B.server_group_id
WHERE B.name = @ServerName
ORDER BY [Level] DESC

T-SQL to get Machine name from SQL Server Instance Name

How many of you use Central Management Server?
How many of you use CMS for just storing the list of servers?
How many of you use CMS for other activities other thank just storing the server names?

The list of servers registered under the CMS can be queried using the view "sysmanagement_shared_registered_servers" present in msdb database.

This will give the list of SQL Server Instance names, but when we require to get the Machine name from the SQL Server instance name, we can use this query to achieve it.

SELECT DISTINCT CASE WHEN CHARINDEX('\',server_name) = 0 THEN server_name
      ELSE SUBSTRING(server_name,1,CHARINDEX('\',server_name)-1) 
      END AS MachineName
FROM msdb.dbo.sysmanagement_shared_registered_servers

Granting Read-Only and administrative access to Central Management Server (CMS)

In one of my previous post, I had discussed about the Central Management Server and how to Register it.
In this post, I will be telling how to give read-only access and a Administrative access to an existing CMS.

Grating the Read-Only and Administrative access to CMS is very simply and the activity includes adding the right database users to right groups in msdb database.

Granting Read-Only access:

USE [msdb]
GO
CREATE USER [DBUserName] FOR LOGIN [LoginName]
GO
EXEC sp_addrolemember N'ServerGroupReaderRole', N'DBUserName'
GO

Granting Administrator access:
This access is usually give to the DBA's

USE [msdb]
GO
CREATE USER [DBAUserName] FOR LOGIN [DBALoginName]
GO
EXEC sp_addrolemember N'ServerGroupAdministratorRole', N'DBAUserName'
GO
