Report blue dot

Hi,

Our manager would like to know the actual hours downtime:

-during working hours and
-during maintenance windows.

It seems to me that this info can only be obtained if the service was
not 100% up during the interval. Then you can drill down to the figure
and see the percentage green, red, blue dot etc.

If the service is 100% up, I only see the green diamond sign but can
not see if the system was actually 100% up and running, or 5% up and
running and 95% blue dotted.

Any suggestions?

Peter
