Performance Analytics - Collect data from 2 years ago

Blair5 · ‎11-07-2017

Is it possible to collect data from 2 years ago? We are trying to implement a quality index based on trending data from the last 2 years. When I try to collect data older than 6 months ago, I get a warning like the below and not sure how to change it:

No list of records (snapshot) was collected between 11-01-2016 and 11-30-2016 for indicator source "Incidents.Resolved". Snapshot within this range is older than the maximum age, based on indicator frequency and snapshot periods, for all indicators associated with this indicator source.

You should be okay with that - the snapshots is just the list of records that you see on the "Records" tab in the Scorecard, so it shouldn't be necessary while you're trying to build a trend. It should only be an issue if you needed to drill down into the records from 2 years ago, which hopefully isn't a requirement.

If for some reason it prevents you from collecting even the SCORES from that period, then you can take a look in the Properties section of PA, and see if there's a property in there that will let you change it. Then you would just change it to something higher than your two years, and then change it back after. There's likely something that will cause those snapshots to be aged off as well, but again, shouldn't impact the scores at all.

I had a similar issue and stumbled across this post however I believe this link explains things

You could change the values below accordingly to allow you to retain more scores or snapshots

Performance Analytics > System > Properties

com.snc.pa.dc.keep_scores_for.frequency

Max scores collected and retained

Default value: 732;105;53;40;60;30;20;20;20;10;10

Daily (732); weekly(105); bi-weekly(53); four weeks(40); monthly(60); bi-monthly(30); quarterly(20); fiscal quarterly(20); half-yearly(20); yearly(10); fiscal yearly(10).

com.snc.pa.dc.keep_snapshots_for.frequency

Max snapshots collected and retained

Default value: 183;26;13;10;15;8;5;5;5;3;3

Daily (183); weekly(26); bi-weekly(13); four weeks(10); monthly(15); bi-monthly(8); quarterly(5); fiscal quarterly(5); half-yearly(5); yearly(3); fiscal yearly(3).
