Analytics & Calculations

If I want to create an analysis that generates an event frame in PI System Explorer, often times it's useful to check the values of variables to make sure that a calculation is being done as expected to mitigate error on my end, and make sure I am...

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 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...

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...

Please allow PI Analysis and PI Notifications to work in an HA setup or in a NLB such as the AF HA recommended scenario. At present the only similar configuration is a failover in a Windows Cluster which TS can't confirm its stability with a NLB p...

Currently you can only run a single PI Analytics instance at a time. We have two VMs running PI Analytics in a failover situation, but this means that one of the VMs is sitting idle 99% of the time. We are starting to hit the limits of scaling w...

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...

PI AF attributes can summarize other PI Point attributes across a time range using value retrieval methods and setting the "TimeMethod" parameter to "TimeRange". When a PI Vision dashboard references these summary attributes, it overrides the time...
