Multiple instances for Asset Analytics
As a PI administrator I would like to be able to create multiple instances of "PI Analysis Service" windows service for these reasons:
- avoid new potentially problematic analysis from affecting the ones that are operational and working correctly by setting one production instance and one test instance for example.
- every instance could have its own log files and we could move some analyses to a new instance to troubleshoot them
- make possible to distribute the resources usage for asset analytics on more than one server153 votes -
Custom functions for the analysis service
As a developer, I would like the analysis service to support custom functions that I write using AF SDK.
114 votesUpdate: This may not be relevant to all subscribers of this idea. Previously we informed via a status update that native MATLAB integration is now available in the 2018 release. This integration will no longer be included with the PI Server starting with PI Server 2018 SP2 release. Please see status on https://feedback.osisoft.com/forums/555148-pi-server/suggestions/17742490-custom-functions-for-the-analysis-service for more details.

Ability to create child Events (EFs)
As a power user or admin, I would like the ability to create child events (EFs) or sub events within AF Analytics SO THAT I can migrate EFGen configurations to something that can be applied to a template and not configured by tags and SO THAT my users can analyze finer time periods of events.
Most common trigger behaviors for a child event are:
* Pulse: values are 0/1 or ON/OFF
* Step: values change and upon each transition, current in-progress event is closed and a new one is created
* Step Continuous: An event is also captured in the…113 votes -
Provide a way to view calculation dependencies
As a a user of Asset Analytics I want to see the calculation dependencies for an analysis so that I can understand which analyses are dependant on an analysis and view potential circular references

Extensible analytics
As a process engineer I would like to be able to integrate complex specific calculations, such as from a 3rd party analytics engine, so that I can use the Asset Analytics and its context with all the available data and scheduling to run those without needing to do custom heavy development.

Improve Management of Asset Analytics
mprove PI AF Analysis Handling in PI System Explorer when working with hundreds of analysis with following features:
- Possibility to sort Analysis/Analysis Templates in alphabetic order by Status, Element, Name, Template
- Possibility to filter Analysis by Status, Element, Name, Template, Backfilling
- Select all filters Analysis to Start/Stop and Start Backfilling
Problem is when a certain set of a analyses are selected so they will be handled in one go. It is not possible to group the required ones in a contiguous section of lines in the PSE Management Add-In, manual selection is taking very much time.-…

Automatic Recalculation of Event Frame in PI Analysis
As a user, I would like to have the option to automatic recalculation of event frame for out-of-order input events in AF analysis. The option is available for expression analysis in PI Analysis 2017 R2 but not for event frame generation analysis.

Event Frame End Trigger Time True Functionality
As a user of event frames, I would like the ability to be able to set a time true condition for the end trigger of an event frame analysis, similar to how this functionality is available for the start trigger

Filter expression for inputs to a Rollup
As a user configuring a Rollup analysis, I want to be able to apply a filter expression on the inputs so that the Rollup only includes inputs that satisfy a condition.

Write custom code for AF Analytics
As an analytics admin, I would like to be able to add more complex code such as Loops, Arrays, and other advanced logic to AF Analytics calculations SO THAT I can perform more complex and custom calculations while leveraging the scheduling and other features of AF Analytics.
43 votesNative integration to MATLAB Production Server is planned for AF 2018 release.
Please contact me directly if you have specific use cases or want to be involved with the beta.
Let me know if this is sufficient.

Be able to disable auto backfilling on a per analysis basis
Currently in the analysis service configuration there is a parameter called “AutoBackfillingEnabled” which affects the analysis calculations in a global basis. It would be great if it were possible to disable the auto backfilling to individual calculations.

Percentile function
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 request WI 44140.

Periodic trigger monthly and yearly
I would like to have monthly and yearly periodic trigger for Analysis-Expression and Event Frame Generation. Currently I have to use the daily trigger and check in the analysis if the month or the year changed. In case of “false” there is no output. In the case of “true” there is an output. This works but it is circuitous.

PI Analysis Performance Checker
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 could run these statistics periodically and notify the user (in the Management tab or in the Analysis tab itself) whenever a PI Analysis has its parameters out of certain values (could cause a bad performance)
So that the users could avoid performance issues more easily.30 votes -
Analytics function for Last Good Value
We have come across a number of occasions where we want to bring in the last good value of an attribute as an input to an analytics. But there is no way to do this without additional attributes and analytics. It would be convenient if a function existed that brought in the last good value of the attribute. This is particularly useful when your data source is known to send NULL value frequent which translate into No Data or Bad Input. One specific example:
We have a number of analytics that only run if one of our engine is on. …

PI AF - Child Event Frames using different template to parent
We currently have Event Frames generating for machine faults, with child event frames then tracking things such as maintenance team response time etc.
Leveraging this data in excel reports is proving difficult however due to the Child Event Frames having the same template and naming convention as the parent.
If Child Event Frames could have custom naming or different templates it would be extremely valuable28 votes -
Support setting data quality related flags from analysis
As a user of Asset Analytics I would like to manipulate data quality related flags (such as quastionable, substituted, etc) from my analysis so that I can set the flag when there is a problem with input value statuses.

Make Analysis trigger on different inputs when timestamps of input tags are equal
If an Analysis is triggered on "Any Input", and the inputs have the same timestamp but come in after each other, the Analysis is only triggered at the first input.
For example: We have a simple Analysis which summarizes 2 tag.
The first tag comes in a 14:00, with timestamp 14:00. This triggers the calculation. The second tag comes in at 14:02 also with timestamp 14:00. Now the calculation in not triggered anymore.We've also discussed this with Techsupport, and they came with the following statement: "With Event Triggered, the first value to come into the PI DA is used…

Compare timestamps and output most recent value in child elements to parent element
From a varying number of child elements (all sharing the same template), I want to find the most recent timestamp of a same template-based attribute, and output the value with timestamp to an attribute in the parent element.
In addition, constantly (event-triggered/periodic) comparing the timestamps of these child element attributes and always output the "newest" value to the parent element attribute.Example:
From 3 child elements, all sharing the same template with attribute "ALARM", I want to have the most recent value comparing the 3 "ALARM"s, and have this timestamp and value in an attribute in the parent element.
