  1. Be able to override the default value for the maximum number of items returned by a query.

    We would like to override the default value for the maximum number of items returned by a query. Currently, the MaxCount parameter needs to be added to every query that will return more than 1000 results.

  2. AdHoc StreamSet actions fail if there is at least one bad WebId

    Currently calling any of the AdHoc StreamSet actions causes the entire call to fail if the request includes at least one bad WebId. It would be better if the response came back successful and only the sub-items with bad WebIds included an error message.

  3. Add bulk delete methods in the Web API

    As a PI Web API user, I would like a simple method to perform bulk deletes of a particular attribute or PI tag. Currently, a bulk delete requires 2 calls. One to retrieve the event I wish to delete and another to delete it.

    Web ID 2.0 should allow you to compute the WebID of a resource without needing to make a call to PI Web API. With that computed WebID, you can make the single call to PI Web API to delete the resource.

    Does this solution meet your needs? Have I understood it correctly?

  4. Allow parameters to be passed to a request body in the Batch Controller

    I would like the ability to pass response values from one request into the body of a dependent request using the batch controller to avoid making 2 calls to the PI Web API.

    Currently,  I can only use Parameters in subsequent URLs, but not bodies.

    The idea still exists on our product backlog, but there are no plans in place to develop and release this functionality at this time.

  5. Add 'Time Zone = Server' to PI OLEDB Enterprise

    'Time Zone = Server' is available in PI OLEDB Provider, but has not been added to 'PI OLEDB Enterprise'.
    We have PI Data Archives in multiple time zones and require the ability to select the data in the server time zone.

  6. 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:

    PLANNED  ·  Ray Verhoeff responded

    We 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.

  7. Implement a checkpoint system for index crawls

    When the crawler fails on an incremental crawl, the index search must perform a complete rebuild of the index. It would be beneficial for there to be a way to revert to a previous built index just prior to the failed incremental crawl so that the index file is available. This is particularly useful for large data sources that take hours or days to crawl before they're usable again.

  8. Expose PI Network Manager Statistics via AF SDK

    As of now, we can get PINetMgr statistics via PowerShell command Get-PIConnectionStatistics. # of users familiar with AF SDK are more than with PowerShell.
    It will be nice feature addition in AF SDK, and usability will also increased.

  9. Automatically update Transpose Function in SQL Commander when referenced Element Template name is updated

    In PI SQL Commander, users can create Transpose Functions that are linked to Element Templates in AF. When the referenced Element Template is renamed in PI System Explorer, the Transpose Function in PI SQL Commander is no longer able to find the Element Template which breaks the Function and underlying Data Table.

    Users are not aware that the Transpose Function or the underlying Transpose Data Table are broken until they attempt to query the Table or Transpose Function.  It would be ideal if the Transpose function could either update this reference automatically or if the function referenced the GUID of…

  10. Offer AF SDK as a Nuget package

    To help with quicker deployment, having AF SDK as a nuget package would speed up development and lower barrier to developing against a PI System.

  11. Allow PI Web API to access the AFPort Class

    Customer is referring to the AF Elements Ports that can be seen with PSE and are implemented in AF SDK in AFPort class.
     
    Customer wants to access to the same features with PI Web API, which is currently not possible. Customer wants to know are there alternative options? Or will it be implemented in Web API in the future?

  12. Add OPCclient to all PI OPC DA server install kit

    In verifying the OPC DA server DCOM setting you need to use the OPCclient to check PI tags values. In the OPC DA server 2017 you need the latest version of OPCclient (was not in OCP client tools) to allow to connect correctly to the OPC DA server 2017. If the OPCclient was in the OPC DA server 2017 I would not had needed to go down load OPC Tools kit.

  13. Add a PI PowerShell cmdlet to find all installed PI software and which installation kit installed it

    As someone tasked with upgrading PI environments, it would be nice if there was a tool such as a PI PowerShell cmdlet that would retrieve all of the version information for all installed PI software on a given machine, as well as which install kit was run to install it. This would help save time during the audit process, before upgrading many servers with the latest version of that install kit.

  14. Expose methods to retrieve messages from the PI Message log to PI AF SDK

    Add methods to retrieve messages from the local and remote PI Message Logs where remote can refer a PI Data Archive node or any remote PINS.

    Because the EventLog Class in .NET Framework provides access to local and remote Event Logs, offering the AF (Server) Event Log through PI AF SDK is not necesarry.

  15. support server side aggregation in AFSDK

    I would like to aggregate multiple tag values in a server side operation using naturally scheduled or sampled intervals in some form similar or extending FilteredSummaries.

    Most common case is finding the maximum aggregate of two or more tags.

    It's not practical to rely on Analysis for adhoc use cases.

  16. Allow subscribing/unsubscribing to attributes on existing channel connection

    The channel/websocket feature of PI Web API would be more useful if it was possible to subscribe/unsubscribe to attributes on an existing channel connection. Currently you have to open the connection with all the WebIds you want in the resource URL. If you want to change which values you are receiving, you would have to close the connection and open a new one. Adding this new feature would also solve issues with maximum URL length limitations.

    This is an issue we definitely need to address for both the reasons you suggested. We should be able to add and remove attributes while a channel is open. We also need a mechanism for signing up for large numbers of WebIds when the list would be too long for a URL.

  17. Allow configuration of the PI OPC DA Server's ProgID

    The ProgID of the 2015 PI OPC DA Server is OSISoft.OPCDA2.DA.1, while the ProgID of the 2010 PI OPC DA Server is OPC.DA.1.

    Existing client tools that pointed to the 2010 PI OPC DA server will need to be reconfigured to point to the new ProgID after the PI OPC DA server is upgraded to 2015.

    While this is done because of an architecture change between the 2010 and 2015 servers, potentially necessitating changes to be made to the client application, it is still desirable in some cases to point it to the new server without changing the ProgID.

  19. Store index files somewhere other than the program data folder

    As a PI system administrator I want to specify where search index files are stored or make sure that the index files are not consuming space on an OS drive , so that I can manage/optimize the disk usage on my server machine.

  20. Add support for AFElement Versions

    Add support for AFElement versions to PI Web API.
    1. Create a new Element Version by defining the effective date and an optional version comment. 2. Add Get and Find methods which support querying AFElements by setting a QueryDate.
