  1. PI Web API Joined should use a format which can be used in PowerBI

    Currently the PI Web Api Joined, delivers the data in a json format which is not really "Power BI" friendly , it would be helpful to have a format where all the datavalues from the subordinated are in the same json object of the base.

  2. Add an action to StreamSets controller to register for updates at element or event frame

    Adding another action in the StreamSets Controller to Register for StreamSet updates in the form POST streamsets/{WebId}/updates with WebId referring a parent object like an Element or EventFrame would be really helpful to get updates for all attributes that belong to an element, similar to Channel controller behavior.

  3. Enable PI Web API to retrieve previous AF Tables versions

    Internal AF table has been updated using AF versioning system, however retrieving it whole with PI Web API only works for current version: GetData method from Table controller (GET tables/{webId}/data) does not accept a time parameter.
    Workarounds involve creating Table Lookup Data Reference attributes or joining all table versions adding columns for time range to be later filtered out.

  5. Add More PI Web API Indexed Search Crawler Scan Interval Options

    As a PI Web API Indexed Search Crawler Administrator, I would like there to be more pre-defined scan intervals available in the piwebapi/admin/search/settings.html page to lower the granularity of the jumps between scan intervals available.

  6. PI Web API should allow the user to configure personally identifiable information (PII) to be shown in logs

    PI Web API 2019 now hides personally identifiable information (PII) in log files. As a PI Web API Administrator, I would like to be able to configure PI Web API to show personally identifiable information in log files, so that it is easier for me to troubleshoot Bearer Authentication issues.

  8. 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.)

  9. Streamsets in form of HTTP POST

    Streamsets controller should have a mirror with http POST calls. It's easier to send data in the body using strongly typed model. (As an example, what if you need to get snapshot values of 1000 pi points). Consider to use POST as a GET in some places where amount of arguments in the url can become an issue.

  10. 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

  11. 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 property

    For 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.

  12. Return Event Frame Attribute Values with GetEventFrames Method

    Currently the GetEventFrames method returns only the properties of the event frame (start time, end time, extended properties, severity, ect.). In order to get a table including the event frame attributes, you need to get the event frame list first and then go through each event frame to get the related attribute values.
    It would be helpful if the GetEventFrames function returned a snapshot of the event frame's attribute values to improve the speed of custom applications.

  14. Allow conditions in Batch Controller

    I would like to be able to have conditionals in my requests to the batch controllers.
    Consider this use case : I want to create an element and its parent, but the parent may already exists.

    At the moment, I have to make 2 seperate calls: One to check if the parent exists. Then a use the appropriate batch requests to create only the child or create both the parent and child

  15. 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.

  16. 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.

  17. allow search where name contains space to return determinant results

    querying for names which contains spaces is non-determinant. AFSDK has methods to search on name, but webapi OR's the search. For results sets which should contain one or few rows, this can result in thousands of wasted rows.

    PI Query syntax EBNF specifies quotedescapedchar, which includes Char, so space should be honored.

  18. Expose UOM Groups in PI Web API

    As a programmer I want the PI Web API to expose an endpoint for reading UOM Groups and UOM Group mappings. This would allow javascript based web applications to read the UOM Groups and mappings in order to use the mappings in subsequent data stream requests. Then the end users could see all data in familiar UOMs according to their selected UOM Group.

    UOM Groups was introduced in PI AF 2017 R2 and is supported in AF SDK 2.9.5+.

    The endpoint could e.g. be at
    https://host/piwebapi/assetservers/{assetServerId}/uomgroups/ and https://host/piwebapi/assetservers/{assetServerId}/uomgroups/{groupId}/mappings/

    A similar request exist under PI Vision product and maybe they can…

  19. Create PI Web API performance counters to monitor the crawl state of various databases

    As an PI administrator I need to monitor the health of the index files created by the PI Web API Crawler. In particular, if the last crawl date has not been updated recently or other errors show up. This is currently done by manually visiting the PI Web API database page. A performance counter that reports things like "the number of databases who have not been updated in 1 hour" or  "the number of databases in error" existed, we could store that info in tags and act on the crawler getting in a bad state in a proactive manner.

  20. Write annotations on archive data via PI Web API

    My client is interested in writing annotations to Stream (time series) data via the PI Web API. I know it's possible to pull this data via the ?associations=annotations query parameters but the write feature is missing.
