Try this one:

IF OBJECT_ID( 'dbo.usp_DeadlockNotification') IS NOT NULL

DROP PROC dbo.usp_DeadlockNotification

GO

CREATE PROC dbo.usp_DeadlockNotification

@FilterBIT int = 0,

@Minutes INT = 30

AS

DECLARE @ErrorLog TABLE

(

LogDate DATETIME NOT NULL,

ProcessInfo VARCHAR(75),

LogInfo VARCHAR(MAX)

)

DECLARE @Count INT,

@StartDate DATETIME,

@EndDate DATETIME

SET @Count = 0

SET NOCOUNT ON

-- Step I: Import Errorlog

INSERT INTO @Errorlog

EXEC xp_readerrorlog

---- Step II: How to search Errorlog

IF (@FilterBIT <> 0)

BEGIN

SELECT @EndDate = GETDATE()

SELECT @StartDate = DATEADD(mi, -@Minutes, @EndDate)

SELECT @Count = COUNT(*)

FROM @Errorlog

WHERE LogDate BETWEEN @StartDate AND @EndDate

AND LogInfo LIKE '%Deadlock%'

END

ELSE

BEGIN

SELECT @Count = COUNT(*)

FROM @Errorlog

WHERE LogInfo LIKE '%Deadlock%'

END

---- Step III: Send Email

IF (@Count > 0)

BEGIN

EXEC msdb.dbo.sp_send_dbmail

@profile_name = 'SQLTestCluster',

@recipients = 'pleblanc@lamar.com',

@subject = 'Deadlocks',

@body = 'Please check errorlog for Deadlocks'

END
