Add Options for PI Web API Call Statistics
Add auditing or a view of statistics for the calls or requests done by each individual application. Allow a PI Admin to see which user or application is making a specific call and see how long it takes to complete to monitor performance and potentially resource intensive Web API calls.
77 votesWe are starting to implement performance counters and statistics for PI Web API.

Complete PI Web API documentation
As a PI Web API user I want to know exactly what kind of Body Parameters (their defaults and description) are supported by PI Web API methods. The current sample requests are not sufficient because they do not describe the values for body parameter, though many parameters have unique restrictions.
Here is an example of desired content:
https://developers.jivesoftware.com/api/v3/cloud/rest/StreamEntity.html37 votesWe have received a lot of feedback on this. We are looking at on-line help with better samples of queries and responses. We are looking at some web frameworks for offering a live “Try It” feature for PI Web API. We are also looking at comprehensive search within the PI Web API help system.

Be able to use RTQP to access PI Points and Config strings (DA Directly)
Be able to use RTQP to access PI Points and Config strings (DA Directly)
Use case:
create a dashboard that lets me know the amount of bad data (tags) mapped to our AF.(eg. “Bad Input”, “Calc Failed”, etc)
Our system has numerous tags and it is impossible to monitor them one by one.
The RTQP engine has allowed us to query massive amount of AF Attributes to get their current values easily.
Some AF attributes have been excluded in our system. For that case, we are not interested whether or not the values are bad.
Hence I would like…

PI SQL Client to make use of the RecordedValue method and Retrieval Modes for the GetValue transposed function
When making use of the GetValue transposed function when creating a new Template specific Data Model, we can see that under the hood it makes us of the AF SDK call AFData.InterpolatedValue method to capture the data at a specified timestamp provided in the transposed function. This method does make use of any Retrieval Modes.
It would be good for this GetValue transposed function to make use under the hood of the AF SDK call AFData.RecordedValue method instead since this method offers the possibility of using Retrieval Modes like "AtOrBefore" which is really useful to capture the last archived value…

PI TagMedian function need to be added in AF analysis.
Please add PI TagMedian function in AF analysis like PI TagAvg and PI TagMean. Currently Median function is available but it cannot be applied for archive values of PI Tags during particular time range
12 votesPlanned for 2018 R2. The Median function will support analytics array introduced with the 2018 release.

PI WEB API - Swagger page
It would be great if as an addition to conventional documentation there was a SWAGGER page with short explanation of methods and parameters (including return types, etc.)

Add data reference impersonation for value retrievals
When retrieving values for attributes, impersonating the user can enable the user of security at the data source level. For example, with a PI Point Data Reference attribute, it could allow the user's authorization to be user at the data archive rather than the PI SQL DAS (RTQP) service account doing the data retrieval.

Import-AFXml (PowerShell) should have ContinueOnError option
Both AFImport.exe and ImportXml (AFSDK) have options to continue on error (like is something is checked out or if there is a duplicate element name). For some reason the PowerShell version doesn't. This should be added.

OSIsoft Python Library for data science
As a data scientist, I would like to be able to use a fully supported OSIsoft Python library without having to directly interface my Python script with a middleware. This OSIsoft Python library would be able to perform the same operations as PI DataLink, but directly in Python. Having this OSIsoft Python library would be beneficial for me because it would greatly improve the time needed to create data analysis scripts and make it a lot easier to interface with 3rd party Python libraries like Pandas for data analysis.

omf endpoint: override type uom in container messages
OMF 1.2 specification includes an enhancement to allow the use of propertyoverrides keyword in container messages.
Request is to add this functionality to Web API OMF endpoint specifically for the uom propertyFor example:
1. device configured with uom, OMF application creates a type specifying that uom.
2 new version of the device changes the uom. OMF application needs to create containers with the new uom, retaining other properties of the type.7 votesThis will be a part of the next feature release of PI Web API.

Time Context Value Retrieval
Example Scenario:
We want to know the Specific Electricity Consumption (kWh/mt) over a time period (selected by users).
Specific Electricity Consumption = (Electricity Consumption(kWh)) / (Raw Feed Consumed(mt))
Where, Electricity Consumption (kWh) and Raw Feed Consumed (mt) are both attributes with PIPoint data reference, using value retrieval method: TimeMethod = Time Range; TimeRangeMethod = Total; EventWeighted
Then, Specific Electricity Consumption is attribute with Formula data reference, simply: A=Electricity Consumption; B=Raw Feed Consumed;[A/B]
So, on PI Vision, it can display the specific electricity consumption with the correct values. However, if we query through PI Web API for our own webpage, it…
7 votesThis can now be done natively with PI Vision 2020 using the Time Range retrieval mode without using PI Web API.

Allow Creation of Acknowledgeable Event Frames
The PI Web API exposes a "CanBeAcknowledged" property when reading Event Frames. However, this property is read-only: it cannot be supplied when creating a new Event Frame or updating an existing Event Frame. I would like the ability to include this parameter when creating an Event Frame.

Create a utility/script that will output the PI products installed, their versions and the most recent version of the product
Create a utility/script that will output the PI products installed, their versions and the most recent version of the product on the machine it is run on. This would help with installations and to manage the current software that is installed.

PI AF SDK Linux Support
As we know there are 2 major competitor for cloud technologies that is Microsoft and Linux destros. If we want to use Linux docker image or PCF Linux image to connect AF SDK, we don't have any provision for this as of now because AF SDK does not support Linux OS. If we support this then most of cloud customer attracts to use AF SDK in their organization.

Include overridden attributes of derived templates in Event Frame View with PI SQL DAS (RTQP)
When you create a template-specific event view, event frames based on derived templates are also returned. However, attributes which are overridden in the derived template return empty. This means more complicated queries using UNION ALL must be used.
As a user, when I use a derived template with an overridden attribute, it is often because I need to change the way that attribute is calculated in a subset of cases. However, I still want to be able to create a view easily for all of this data.
For example, I have a "Batch" template with "Pounds Produced". However, for a…

PI Web API OMF send to multiple PI Systems
I would like to be able to setup the PI Web API OMF endpoint to point to multiple PI Systems, so that way it is easy to send from this single instance to different production systems or to our development and production environments concurrently

Be able to expose AF with PI OPC DA Server
Today PI OPC DA can only expose tags from DA.
To have the option to expose information from AF.
Both the AF structure and attributes.We are using AF for everything so why not in PI OPC DA.

Rebuild Index is not working as expected
In the https://pivision-us.oxy.com/piwebapi/admin/search/database.html page the Rebuild Index button does not work. It should allow the pi vision administrator to immediate re-indexing of individual AF database at the time without affecting the usability of the others.
4 votesWe understand that it is confusing to not be able to rebuild the index unless you are a member of the PI Web API administrators group, even though we are requesting to rebuild from PI Vision. With that said, with PI Vision 2020, the PI Web API Search Index is no longer used for PI Vision’s search, and the PI Web API service can be safely disabled after upgrade, so long as its only consumer was PI Vision.
