Mail Alert when threshold of 10000 pendingcmds are breached

dba.stackexchange https://dba.stackexchange.com/questions/216877

Domanda

I currently have the below running to monitor replication and send a mail when the threshold of 10000 pendingcmds are breached, however the alert mail is generated every 5 minutes regardless of the threshold. I need assistance to re-code the threshold part as this is not delivering the expected results. 

        DECLARE @RESULT nvarchar(100)
        DECLARE @cmd varchar(100)

        SET @RESULT = ('SELECT pendingcmdcount FROM #pendingcmds') 
        EXEC sys.sp_executesql @RESULT
        PRINT @RESULT
        IF @RESULT > '10000'

Code used to generate alert

        USE [TestDB]

        create table #pendingcmds
        (pendingcmdcount int,
        estimatedprocesstime int)

        Insert INTO #pendingcmds (pendingcmdcount, estimatedprocesstime)
        select * FROM OPENROWSET('SQLOLEDB', 
        'Server=Server\Instance;Trusted_Connection=yes;', 
        'set fmtonly off; 
        exec distribution..sp_replmonitorsubscriptionpendingcmds 
        @publisher=''Server\Instance'', 
        @publisher_db=''testproduction'', 
        @publication=''Summary_Inventory_TestProduction'', 
        @subscriber=''Server'', 
        @subscriber_db=''TestReplAzure'', 
        @subscription_type=0')

        SELECT * FROM #pendingcmds

        --DECLARE @RESULT nvarchar(100)
        ----DECLARE @cmd varchar(100)
        --

Soluzione

The following suggestions are not fully tested.

Immediately after

Insert INTO #pendingcmds (pendingcmdcount, estimatedprocesstime)
select * FROM OPENROWSET('SQLOLEDB', 
'Server=Server\Instance;Trusted_Connection=yes;', 
'set fmtonly off; 
exec distribution..sp_replmonitorsubscriptionpendingcmds 
@publisher=''Server\Instance'', 
@publisher_db=''testproduction'', 
@publication=''Summary_Inventory_TestProduction'', 
@subscriber=''Server'', 
@subscriber_db=''TestReplAzure'', 
@subscription_type=0')

I would delete any rows where your threshold was not met.

DELETE FROM #pendingcmds WHERE pendingcmdcount <= 10000

Then, I would change your test for whether to send the email or not

From 

IF LEN(@HTML) > 10 

            EXEC msdb.dbo.sp_send_dbmail
            @recipients = 'tester@test.com',
            @body_format =  'HTML',
            @body= @HTML,
            @subject = @MailSubject,
            @profile_name = 'MailRelay'

TO:

IF (SELECT COUNT(*) FROM #pendingcmds) > 0 
    EXEC msdb.dbo.sp_send_dbmail
    @recipients = 'tester@test.com',
    @body_format =  'HTML',
    @body= @HTML,
    @subject = @MailSubject,
    @profile_name = 'MailRelay'
