SSIS: Check for Connection Manager Login Fail

Hi Experts,

I have an SSIS package that runs on task scheduler everyday. The main thing is there is an OLE DB connection manager to an SQL server and it's been set on the server that this password must be updated every 3 months which of course causes a package failure.

Now. Is there a way I can somehow capture a login failure in this connection manager and use the send mail task to mail me when this happens? It's not as easy as using an event handler I don't think anyway...

Thanks,

OS

There are several ways you can audit failed login attempts to SQL Server, but one way which sounds suitable for your specific case is xp_readerrorlog proc; for instance try the following:
DECLARE
  @StartTime DATETIME = GETDATE() - 100
, @EndTime DATETIME = GETDATE();
EXEC sys.xp_readerrorlog 0, 1, N'Login', N'failed', @starttime, @endtime;

You can modify the WHERE clause to filter the result specifically for the particular login that's used by your SSIS package.
Anyhow after detecting the failure you can use sp_send_dbmail or similar to send a notification to yourself.

Alternatively you can be proactive and check the login in the context of a separate job that runs more frequently or ahead of that SSIS package to allow you detect and resolve the problem before it affects your SSIS.

You can also use this method to proactively monitor all failed login attempts for all other logins (be it accidental or malicious) to stay on top of the game.

Thanks mate! Although it works and I can perhaps try to experiment with a way to pass some variables from the returned results into an SSIS variable and then perhaps use that to trigger a send mail task.

At the moment though I'm unable to execute sproc on the server of interest. Thanks anyway.
