Currently PI Analysis Service has a built-in Statistics tool in PI System Explorer. It is able to show statistics regarding Evaluation and Calculation Lag as well as Skipped Evaluations and some other important information. PI System Explorer ...

As a user of analyses, I would like to have a Percentile function so that I can filter out atypical events when doing summary calls. The function would look like this: Percentile('attribute', 'timerange', value). This is related to enhancement req...

I would like to be able to configure outputs in an analysis to write at multiple time points (which are defined by the result of an array function). My use case is to: 1. Configure an attribute as a Time Series Table Lookup 2. Create an analysi...

When editing an Analysis Expression, only 4.5 lines appear. It would helpful if more lines appeared (greater than 20 lines).

It would be useful to add a feature to list notifications by user. This feature would be helpful in managing the list of notifications as more notifications are created and as users change job roles.

As an analysis user I would like to define what should happen if multiple triggers occur with the same timestamp. Currently AF analysis are using "Replace" mode when writing to the archive (meaning if multiple triggers have the same timestamp, the...
