Analytics & Calculations

I use analysis to toggle a boolean or integer from 0 to 1. This is used as source to close/open event frames (step continious mode). this is working fine in real-time. But when I do a recalculation for a part of time in the past (not until *) on t...

It would be nice if we could have a "real-time" and "recalculate" part in an analysis. As source data could have changed you probably want sometimes the analysis to act in another way. Example: 2 attributes are used to trigger an event-triggered a...

There should be a way to monitor if the analysis service is running, other then just checking if its running from services, or that analysis service is not connected on PSE. There are no specific performance monitor counters that monitor such a th...

Add some metadata to analysis statistics to identify which analyses are outputting to PI Points, which are configured as an Analysis Data Reference and which are a mix of both. Currently this isn't identified and can cause some confusion. For exam...

We have cases where we have several values for the same tag at a specific timestamp. When we use tagVal in an analysis expression, the TagVal function returns the last stored value for the timestamp for the tag. We would like to be able to get (us...

When an Expression or Event Frame Generation analysis evaluates for the first time, the function HasValueChanged returns True even if the value has not actually changed. More proper behavior would be to default to false. The same holds true when m...

Upon an analysis service restart, the service will backfill and recalculate for the time range specified by the MaximumAllowedAutoBackfillingSpanInHours service configuration parameter; the default is 72 hours. Starting in PI Analysis Service 2.8....

Found out that the decimal points is up to 3 decimal only. Can you improve the PI Integrator that has its own decimal places? and also not depending on the AF for adjusting the display digits? Thanks

When having calculationWaitTimeInSeconds set to a large value in combination with an AF-SDK app triggering recalculations, it can happen that recalculation writes a value at timestamp x before this analysis is triggered to run in real-time for tim...

Having the ability to store analysis variable configuration (calculation) in an attribute value would help a lot in creating assets from template that have diverging analysis configuration. For example, an attribute named attribute1 with a strin...
