Analyzes are automatically switched off by the PI Analysis Service
In the case, that the PI AF Analysis Service is overloaded, there should be the possibility that faulty analyzes are automatically switched off by the PI Analysis Service. This ensures that all other analyzes functioning correctly. The failed anal...
Add a quadratic regression function similar to "LinRegr". This would be helpful for trending relationships that are not linear, such as flow vs. pressure.
Analysis timerule option: Add a possibility to make the timerule conservative. Emit calculation events only if the snapshot time of all inputs are more recent than the planned calculation time.
Now the TimeRules Natural and Periodic emit events to the Data PIPE in case NATURAL: an event is received by one of the selected inputs case PERIOD: when a certain timespan elapse.Both method doesn't take into account that some input of the analys...
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...
Provide a tool (in PSE?) to assist management of analytics scheduling offsets
We recommend customers use offsets to distribute scheduled calculations across time but there is not a good way manage this.Propose some utility to list a group of all scheduled analyses by same period, users supply X number of offsets and then th...
When trying to troubleshoot analyses and templates that may be causing poor performance on the "Management\Performance" tab, it can be tedious to locate the selected element to start determining why it's building in error count or taking a long ti...
Preserve variable-attribute mapping upon attribute path change
Currently, if a variable is mapped to an attribute and the attribute's AF path changes, the variable must be remapped to the attribute.

Is it possible to enable or disable the parameter EnableAutoBackFilling for different group of Analysis in different database.
The idea is to not have same parameter EnableAutoBackFilling for all Analysis of all databases on the same ...
