Analytics & Calculations

Analyses can suffer from bad calculations due to bad events for a tag, such as system digital state events returned for a numerical tag. Although BadVal() can be implemented to avoid using bad events in these analyses, they add another layer of ...

It would be useful to trigger event-triggered rollup analyses upon adding new children. Currently rollup analyses are only triggered when rollup attributes are updated (and not triggered when rollup attributes are added). This would be particularl...

PI System Explorer Management Tab should have better search criteria. For example, select specific elements in which to rerun an Analysis. Maybe use Element = something OR/AND Element = something else. Or search by element path.

It is difficult to find all the analyses from template to backfill/recalculate after making changes in Analysis Template.  Currently one has to navigate to the Management plug-in, do some sort of search/filter, then queue the analyses.  ...

When a failover occur or at service startup, ALL analysis configured for backfilling executes based on the last configured backfill/recalculate timerange. There is actually no feature to manually remove a configured backfill on a specific analysis.

Currently we have an analysis with the output timestamp set to be a variable within the analysis. If I map that variable to an output, it includes the subseconds, but the output time for the analysis is truncated to the second. The output time for...

This would allow for validation of input unit of measure during expressions.

Allow arguments/parameters to be passed to variable definitions, effectively creating user-defined functions. For example, suppose that I want to define the function TagSum, which adds the values at all events in a time range. Then: TagSum(tag, s...

Currently Rollup triggers can only be "All attributes" or periodic. But sometimes, especially when you are dealing with lots of attributes been rolled up together, you may want to specify one (or a couple) attributes to the be triggers of your Rol...

The current 'Analysis Service Statistics' explain quantitatively "what is happening", but do not quantify the available capacity of the analytics engine. Managing a large and busy AF Server involves far too much guesswork as to how much additional...
