The Pi Tags with values generated by analysis are not updating even though there are no errors. The timestamp has been stuck there.
Other types of tags are working fine, however.
Adding similar condition like below to your calculations might be a fix:
How is the analysis scheduled? Periodic or event based? Are there new events on the tags?
I tried badval NoOutput. It didn't work.
They are event triggered. Triggered on any input. Also to add, all other analysis, not just these stopped at the exact same timestamp.
i see that your last trigger time is 3/8/2020 12:02:26 AM . This seems to me as it is working as expected.
Check your inputs to Analysis - All your Trigger points doesn't have any events after 3/8/2020 12:02:26 AM
From another analysis. My Inputs are BTU Charge and BTU Discharge.
Can you try Backfilling ?
Without knowing what the actual issue is it is hard to trouble shoot. It would take forever here to understand what the actual issue is. I would recommend calling Tech Support !

Step 1 : Check preview result by right clicking the analysis to understand the trigger values vs output.
Step 2 : Check last trigger time and latest value in input tags
Step 3 : Restart the analysis and backfill if required.
Step 4 : Check AF anlaysis logs for additional information.
Seems like your outputs are stale. The analysis is most likely skipping or lagging. I'd recommend reading over Nitin's blog post below to understand better. I'd also recommend reading over our best practices to make sure your analyses abide to them.
