Ideas

I would like be able to use a variable as index instead of an integer number in \Elements[@index=variable] so I can always get attribute values of my child elements eventough the relation to my child element isn't always the same.

It would be nice if the configuration of an analysis was saved in memory when switching between types (expression, rollup, event frames or SQC). This way if a user accidently changes type, their work would not be lost.

During bulk recalculation or backfill, enhance the PI Asset Analytics engine to prioritize the calculation of analyses that act as inputs into higher level "daisy" chain analyses. This would address performance issues at large scale, as described ...

I find myself making analytics on child elements which by themselves have limited value, but are needed to get rollup analyses to work. This adds complexity to the design of AF. Two ideas would improve this: 1) Count # of attributes that meet a c...

Some Analytics fail due to a tag not existing. It is possible to test for a Bad value via the BadVal() function, however, this does not work if the tag does not exist. Consequently the equation will not run. This caused me many hours of debugging ...

I would like to create a custom AFAnalysisRule that allows us to leverage the resources on the PI Analysis Service to perform calculations that the Analysis Service currently cannot perform. These calculations include matrix operations, array oper...

Currently the Severity of the EF is set on the template. The severity of a start trigger allows to create child events. I want to have the ability to have the severity of the start trigger set the severity of the generated EventFrame. In that way...

PI assumes that the value of a PI Point from its snapshot event up to now is equal to the snapshot value. This extrapolation is not necessarily a good representation of what the interpolation will look like when new data arrives. The extrapolatio...

#of assets (in this specific scenario): 500-1000 EF Count: Generation rate of 25,000/day peak, would like to historize for 1+y = 9,000,000 events+ Attributes: 5-10 attributes/event (static or PI Point) Flat Hierarchy Queries: EF are alarms or ...

Because event frame start and end time are stored as a bigint datatype in PIFD.dbo.AFEventFrame, the precision only seems to be to the nearest millisecond. This is a problem for sub-millisecond event frames. Why aren't event frame start and end ti...
