Cluster computing: Creating automated load test run report reminders

Load Test Run results can be populated in a database. Scripts to set up this database are available here.
In order to send automated reports on new results, we can register a trigger and an xslt transformation like so:

USE PerfResults;
GO
IF OBJECT_ID ('dbo.LoadTestRunCompleted','TR') IS NOT NULL
DROP TRIGGER dbo.LoadTestRunCompleted;
GO
CREATE TRIGGER dbo.LoadTestRunCompleted
ON LoadTestRun
AFTER UPDATE
AS
DECLARE @RunID uniqueidentifier;
SELECT TOP 1 @RunID = RunID from LoadTestRun where Outcome = 'Completed' order by EndTime desc;
DECLARE @msg nvarchar(max);
SELECT @msg = dbo.fn_DisplayLoadTestReport(@RunID);
EXEC msdb.dbo.sp_send_dbmail
@profile_name = 'Performance Reports Administrator',
@recipients = 'user@xyz.com',
@body_format='HTML',
@body = @msg,
@subject = 'Automated Performance Reports' ;
GO
