Discovery Schedules Conditional Scripts

[ScottR]

Hi, is it possible to schedule the following times on a discovery schedule:
1. First Tuesday of the month from 20:00 - 21:00 - Test environment
2. Second Tuesday of the month from 20:00 - 21:00 - Stage / UAT environment
3. Third Tuesday of the month from 20:00 - 21:00 - Prod environment

and is the best way a script?(if so could some one help me as i am a noobie at best when scripting)

You can create a flow and call this API on the desired dates.

Hey Scott,

It's doable (see "periodically" as you configure the schedule, assuming you have separate IP ranges / subnets for Test / Stage / Prod) - but I'd question if it were wise. What would happen, for example, if a server was updated immediately after July's Discovery job were updated? It would be inaccurately reflected right until August - which would cause manual work or process avoidance for those using the CMDB (to raise changes and so on). 

Personally, I'd schedule them to run periodically, sure - but be careful not to leave it too long between jobs. The value of Discovery is in its' accuracy.

Hope that helps!

Due to the nature of our business, we are only allowed to scan these ranges at the specific Tuesdays, and this is my dilemma. Having the schedules know which Tuesday it is in the month.
