Check linked server status in SQL Server

We can ping server from SQL Server in other word we can check current
status of linked server.I have tried to write a T-SQL for this.

DECLARE @ServerStatus TABLE
(IPStaus VARCHAR(500))
DECLARE @PingIP varchar(1000)
SELECT @PingIP = 'ping ' + 'xx.xx.xx.xx'
SET NOCOUNT ON;
INSERT INTO @ServerStatus
EXEC master.dbo.xp_cmdshell @PingIP
IF EXISTS (SELECT 1 FROM @ServerStatus WHERE IPStaus LIKE  '%Request timed out%' )
BEGIN
    PRINT 'Server does not exist'
END 
ELSE
BEGIN
    PRINT 'Server available.'    
END 

That’s It
