A few limitations make difficult to architect AIM with PI 2023: No support for NLB No support for failover cluster No support for multiple independent AIM instances As of today, AIM is a single point of failure and so HA is required to preven...

Use case: User wants to trend Analysis Data Reference in client tools (Processbook, Coresight). User doesn’t want to create a PI tag for this output. Currently, the AnalysisDR ignores step, even if it’s input attributes are step.

Currently in the analysis service configuration there is a parameter called “AutoBackfillingEnabled” which affects the analysis calculations in a global basis. It would be great if it were possible to disable the auto backfilling to individual cal...

We have come across a number of occasions where we want to bring in the last good value of an attribute as an input to an analytics.  But there is no way to do this without additional attributes and analytics.  It would be convenient if ...

As an engineer, I want to execute analyses when I get a new future data value, so that any forecasts (either via Analysis or via a 3rd party system or via a PI Point update) can trigger analyses.

As an AF Administrator, I want to configure an Analysis Template for Event Frames with a True For parameter that would have it's value stored in an AF Attribute (configuration item). The use case is that elements built from the template will have ...

I would like to have monthly and yearly periodic trigger for Analysis-Expression and Event Frame Generation. Currently I have to use the daily trigger and check in the analysis if the month or the year changed. In case of “false” there is no outpu...

The arrays in Expression and Event Frame Generation analyses are useful, but use cases are emerging where more functions are needed to reduce/calculate the arrays in more streamlined fashion. For example, Concat function should support array of ch...

If an Analysis is triggered on "Any Input", and the inputs have the same timestamp but come in after each other, the Analysis is only triggered at the first input. For example: We have a simple Analysis which summarizes 2 tag. The first tag comes...

There is a considerable amount of downtime in our system (20+ minutes) when a template change is performed. The root cause is a limitation on how the analysis service handles the removal of AF Attributes from the Data Cache. Due to this limitation...
