Hi team,

I would like to understand how PA calculates the data based on daily and historical data collection.

Lets say there is a PA report/widget which provides a score (lets say compliance score) of x% based on number of open incidents, breached SLAs, incident not breached SLAs, incidents resolved in time on daily basis.

1. how does it calculate the values when we change the report overview to "by month" or "by year"

2. how does it calculate the breakdowns such as category, assignment group, priority etc.

It takes daily snapshots, so the data is simply shown on a different interval. 1000 per month will just show 12000 a year. There is no recalculation done on the data itself when you change the report overview. Same goes for the breakdowns. They are stored from the daily snapshots you let the system take.

Be aware: if you run the 'historical data collection' on an indicator that is already collecting daily, it captures the current data and it will mess up your history, if you are checking on states or things like that. For the stuff you mention it probably wouldn't matter much (a breached sla is still breached, as it was before), although assignment groups and priority breakdowns could give issues.

Hi @Mark Manders ,
Thanks for responding to my question, so if an incident was not breached on day 1, day 2 and breached on day 3, during the weekly/monthly/yearly calculation does the system calculate 3 different scores?

No. It takes a daily snapshot and does a daily calculation. So if you are collecting 'breached sla' records, that incident_sla record isn't collected on day one or two, but is on day 3.

And if you collect all and you collect the breached ones, it is collected on all days and the breached one only on day 3. And the daily calculation will show you that you have a changed percentage on day 3 (probably, depending on the exact data).
