Reporting Monthly Application Availability in report writer

Hi all,

A little stuck on SQL here...

I have this.....

SELECT  TOP 10000 Nodes.Caption AS NodeName,
APM_AlertsAndReportsData.ApplicationName AS Application_Name,
APM_ApplicationAvailability.PercentAvailability AS ApplicationAvailability

FROM
(Nodes INNER JOIN APM_AlertsAndReportsData ON (Nodes.NodeID = APM_AlertsAndReportsData.NodeId))  INNER JOIN APM_ApplicationAvailability ON (APM_AlertsAndReportsData.ApplicationId = APM_ApplicationAvailability.ApplicationID)

WHERE
( DateTime BETWEEN 42276 AND 42306.9999884259 )
AND 
(
  (APM_AlertsAndReportsData.ApplicationName = 'IPFX Service Manager') OR
  (APM_AlertsAndReportsData.ApplicationName = 'Google http test') OR
  (
   (Convert(Char,DateTime,108) >= '08:00') AND
   (Convert(Char,DateTime,108) = '18:00') AND
   (DATEPART(weekday, DateTime) >= 2) AND
   (DATEPART(weekday, DateTime) <= 6))
)

ORDER BY 1 ASC

However this gives me all the data. I really just need 1 monthly average and not the 2000 results it bring back.

Any one have any idea?

TIA,

Grant
