Analytics & Calculations

The TriggeredOn() function would return true if the inserted attribute was the reason for the expression analysis to trigger/evaluate. I have multiple attributes in the same analysis but only want each line to have an output when its corresponding...

When using the preview analysis function an an analysis with many variables the preview graph and table struggles to keep up, and uses a long time to update. When there are many variables, these are also quite useless. It would therefore be an i...

I would like the ability to flag an SQC event only if I am in a batch, on a grade run, or in some other process condition. Right now, I am getting an SQC outside control limit when my phase is "inactive." Let there be more configuration of this in...

If an existing digital state is edited, PI Analysis Service does not recognize the change until it is restarted. A digital state should not be edited too often. However, it would be useful if there is a process to update cache, including each digi...

As PI server administrator I would like that when the Analysis service is restarted with autobackfilling enabled, if there are any EF analysis where last evaluation time is older than *-MaximumAllowedAutoBackfillingSpanInHours, EFs that are opened...

The PI data archive (and potentially other systems) can generate many automated error messages to assist with troubleshooting. One such key example is "[-10767] Client exceeded maximum concurrent queries in RPC thread pool", which occurs when a se...

The analysis tab in PSE can take quite some time to load if there are thousands of elements being referenced in the input attributes. This is rare for Expression, Event Frame and SQC analyses, but not as rare for Rollups. Ideally the tab should lo...

When you develop an expression it is very useful to use the preview function. Quite often you can discover and debug directly from this, but you are not abel to close down the window and check the code! So either you memorise or you export the cs...

The PrevVal function currently requires two parameters: an attribute and a timestamp. However, I find that 90% of the time that I use this function I am looking for the previous value with respect to the current time ('*'). The error which analyti...

Like Mathlab, Octave is a powerful free calculus software which is used commonly in machine learning. I think it could be a good idea to integrate this software with PI Analytics just for these purpouses and others like just make advance calculati...
