I was just in contact with tech support regarding this known issue: https://techsupport.osisoft.com/Troubleshooting/Enhancements/116559
An example at one of our customers:
Input tags in an analysis receives data from an interface 5-mar-16 with timestamp 1-mar-16. The AF server was restarted 2-mar-16 due to maintenance.
The output tag of this analysis will then not trigger 5-mar-16 with timestamp 1-mar-16 due to the fact that this event is before the PI Analysis Service was started. So we have to do a manual backfill.
Since there is no known workaround for this, does anyone have any suggestions on how to solve this?
Should we develop our own service that checks at some given interval if there's any backfill "gaps", and then start a backfill from within our service?
Any help is much appreciated!
