Instance Scan - Prod or Non prod?

[Bruce Hadley]

What is the best practice on setting these up to run? If it is in a sub prod wouldn't the data disappear after a clone? Would running these checks in Prod be best so that it could be connected to stories or incidents and you would also have a history?

If we run these in prod, is there any negative effects like performance?

I can see use cases for running these scans in prod and non prod instances. My thoughts on doing them in prod is to show progress. For example one scan checks for favorites without filters. If I set this up in prod i can run it weekly or monthly, first to have users clean them up, but if I do it in a sub prod, I could only check after a clone.

Others might need to run in prod due to Clone excludes. So it would be nice as we look at remediation to have it in prod, I just don't want to do a full scan and cause issues as I know the SN run Healthscan is only done in sub-prods.

A full scan on production does not have to be an issue.

The issue is more, that if you create your own scan checks, you could also create some really awkward ones or using really bad performing scripting. Just like when developing Business Rules, Flows, etc.. If those are ****, it will impact your instance. Instance Scan checks it's no different 🙂

Concerning "SN run Healthscan is only done in sub-prods"

You can't really compare HealthScan and Instance Scan. Instance Scan is a part of your instance, while HealthScan runs remote.

Thanks, I get the idea of introducing new checks, that part of the "do it in sub prod first" first. But if running the OOTB checks in prod has no bad effects i think I'll go that route. I have already done in it a sub prod.
