    Preview Results should remember the start and end time

    As part of debugging, sometimes I use Preview Results (which is available from right-clicking on an analysis), make some changes, and then use Preview Results again. It would be useful if PI System Explorer would remember the start and end times ...

    Auto-Regroup PI Analytics

    Behind the scenes, Analytics groups calculations during startup of the PI Analysis service.  However, after startup, sometimes an Analysis 'falls' out of a group and cannot be added back.  This returns the error message, "Failed to inser...

    scheduled recalculation

    For our technical account we have to do recalulations on a daily basis, because of late arriving data. Auto-recalculation is not an option, because late arriving data that arrives after we have published the results, should not(!) be respected any...

    Limit the load of the PIRecalculationprocessor when backfilling

    We had a few issues with key-users creating inefficient AF Analysis and starting a backfill over a longer time period. This resulted in a CPU load of 100% (caused by the PIRecalculationprocessor). The whole PI System got not responsive incl. PI Sy...

    Option to not have Value Retrieval Method and TagTot "fill in the gaps"

    When taking a Total using Value Retrieval Method (configured in AF Attribute) or using TagTot (an AF Analytics function), PI will "fill in" gaps in the data. For instance, if you have a Float32 tag that is reading good for half of the day and then...

    Allow BadVal to handle 'No Data' when querying before input tag creation

    It is currently not possible to use BadVal and if-then-else logic to handle the 'No Data' system digital state which is returned by a formula data reference or analysis data reference attribute when one of the input tags for the calculation was cr...

    PI System Explorer > Preview Results: trends should allow for Inputs/Outputs to be selected/deselected

    It can be difficult to clearly see the input/output trends in the prevew when trying to perform debugging. Specifically it would be useful to isolate the mapped output(s) to see if the analytic it producing the expected results. The table is usefu...

    Expose Analysis Service Evaluation Queue Count

    For complex systems it is important to monitor the PI Analysis Service closely. The existing performance counters are helpful but we would really like the EvaluationQueueCount to be available as well. This would help determine if the EvaluationsTo...

    AF function PrevEvent() should return timestamp of previous event even if data is "No Data"

    Normally AF function PrevEvent() returns the timestamp of the previous event for a specified timestamp. But if the previous event is system digital state "No Data" it does not return the timestamp but again system digital state "No Data". That is...

    Add the Analysis Description as a column to the PI System Explorer Management

    When I open PI System Explorer and click the Management button in the bottom-left I'd like the ability to show and hide certain columns of information; for example, I'd like to be able to add the Analysis Description as a column.
