(Availability) Calendar based on two dates

Tue, 09 Feb 2016 12:24:51 GMT

Hi,

I'm trying to calculate availability for some servers and I'm trying to figure out how to do this based on two dates and duration of the event. This is how my table looks like:

As you can see there is one server (ID 9) that's been down for little more than two months. I want to "split" this value so I can show duration for each month. For this server I would like to able to visualize it like this:

2015-07: xxxx seconds (first_date - 2015-07-31 23:59:59)

2015-08: xxxx seconds (2015-08-01 00:00:00 - 2015-08-31 23:59:59)

2015-09: xxxx seconds (2015-09-01 00:00:00 - end_date)

Check this out for creating calendar based on two dates: Canonical Date

I wouldn't use Canonical dates for this. Instead I would create reference dates within the intervals. See See Creating Reference Dates for Intervals.

The script could then be

Load *,

Month(Date) as Month,

EndTime - StartTime as Duration;

Load *,

Time(If(first_date>Date,Frac(first_date),0)) as StartTime,

Time(If(end_date<DayEnd(Date),Frac(end_date),Frac(DayEnd(Date)))) as EndTime;

Load

ID,

first_date,

end_date,

Date(DayStart(first_date)+IterNo()-1) as Date

From <Source>

While IterNo()<=1 + DayStart(end_date) - DayStart(first_date);

Then you get a field with the duration within each date, so you can create a bar chart with month as dimension and Sum(Duration) as measure.
