Percent network availability pie chart

Hi,

I’d like to create a network summary report using the web-based report writer.

On the front page I would like to have pie charts showing entire percent network availability for the past month, then below that availability per region (AMER/EMEA/APAC).

Looking at the out-the-box reports there is one called “Availability of Entire Network - Last Month” – and I think I might be able to use that.

The SQL used for that report is:

SELECT  TOP 10000 AVG(ResponseTime.Availability) AS AVERAGE_of_Availability

FROM

ResponseTime

WHERE

( DateTime BETWEEN 42977 AND 43006.9999884259 )

Problem is that I am unable to use this to create a pie chart.

I’m also not sure how the DateTime formula is working.

Can anyone help?

Thanks.
