  1. Separate priority setting for Data Read and Data Write

    Data Read and Date Write (Buffering) from/to PI Data Archive is based on the priority settings in PI SDK and PSE. We have a architecture of 6 member PI collective and all the source data is not buffered to the individual collective. Hence for other applications like PI Analysis or any other 3rd party applications data read should from couple of collective members and data write should be to 4 collective members.
    As per the current setup, if we enable the priority for 2 members in collective, data read and write is happening only for those members (Default behavior). But…

  2. Future Plans for Notifications High Availability?

    General Query:

    What are the future plans for High Availability of PI Notifications.

    To my understanding, the only option providing seamless failover is to utilise a Windows Server Failover Cluster, with high performance Shared Storage to hold the Notifications RunTime files.

    Are there any plans to make Notifications stateless, and store all data in SQL, where SQL AlwaysOn Availability groups can be utilised?

    Feedback much appreciated.

  3. Support AWS RDS SQL Server instances as backend DBs for AF and PI Vision

    Our company is progressively superseding the deployment of hosts with SQL Server installed, while moving towards the usage of SQL Server instances provided by AWS' Relational Database Service as the DB backend. Although currently OSISoft does not officially support the usage of RDS instances as backends for AF and PI Vision, we performed some internal tests with both AF and Vision and they seem to be promising. We would like OSISoft to study this kind of solution and, if there are no major obstructions, provide official support for such scenarios.

  4. Optimize the storage and retrieval of digital tags

    Given that the archive file format is proprietary, this suggestion is me shooting in the dark.

    Disk compression compresses archive files very well, and my guess is that most of this compression occurs on the digital tags, since the number of possible values that they can take on is limited. In contrast, the number of possible values that a floating-point tag can have is huge, so there is not much opportunity for compression.

    Please consider optimizing the storage of digital tags so that their data takes up less space in the archive and can potentially be retrieved faster.

  5. Filter/Flag PI System Generated Error Message as Analysis Inputs to prevent False Positive Evaluations

    The PI data archive (and potentially other systems) can generate many automated error messages to assist with troubleshooting. One such key example is "[-10767] Client exceeded maximum concurrent queries in RPC thread pool", which occurs when a service (such as AF Analyses) doesn't have adequate threads to retrieve input values.

    If this error is given because of a system issue, the Asset Analysis service will still process the logic with that error message being used a generic string. If the logic is something similar to Input <>1, then this would resolve as TRUE. In this scenario, this would be a…

  7. Enable Compression for recalculated Analyses up to "Now"

    Analysis Recalculation produces Out of Order Events, which means they are not compressed.
    The reason for this behavior is, that there is a more recent snapshot value existing. This also happens, when Recalculation is performed till "Now" (*), because the Analysis Service performs the Recalculation in chunks (see "Will PI Analysis Recalculation follow compression and exception?")

    Would it be possible to make the Analysis Service first delete the time range fully (when recalculating up to "Now") and let it perform the recalculation in chunks afterward?
    This would not produce OOO Events and compression can be applied.

    The only workaround at…

  8. Make badval() in Formula data reference equivalent to BadVal() in Analytics

    Currently, BadVal() in Asset Analytics can handle situations like BadVal(1/0) without throwing a divide by zero error, but the badval() function in the Formula DR cannot. The request is to make them equivalent so that behavior is consistent across the product.

  9. Ability to manage non-impersonated linked tables without PI AF Server Admin privilegies

    PI AF Admin would like grant permissions for users that are not level server admins to create and edit non-impersonated linked tables. Currently this only allowed for AF server admins or using impersonated linked tables.

  10. Optimize and compress non-primary historic archive files

    Currently, the same file format is used for primary and non-primary historic archive files. This does not make much sense since the two types are used very differently.

    For the primary archive:
    • Write operations should be fast since it is collecting data in real-time
    • Read operations should be fast since the most recent data is usually the most relevant
    • File size is not a concern since there is only 1 primary archive

    For non-primary archives:
    • Write speed is not a concern since write operations are infrequent
    • Read operations should be fast because users may want…

  11. Web Service Configuration - Dynamic "Path" for the JSON Body

    Allow free-form JSON construction. Maybe not replace the simple JSON guide that is the only entry form now, but free-form would allow the kind of flexibility that would empower the user.

    This would allow a single template to be used, rather than the workaround to manually override the template for every individual sensor configured, resulting in hundreds of template copies in which only the "Path" field is edited

  12. Add the option to delete all event frames that reference an element when the element is deleted

    When deleting an element using PI System Explorer, there should be an option to delete all event frames that reference the element. Currently when deleting an element, the delete option "Delete this object and all references to it" does not delete the event frames that reference the element. This delete option only deletes the references that are inside the event frames.

    If a deletion of an element occurs, then there could be lots of undesired event frames that have no referenced element in the database. And to find these event frames, it would be necessary to use another tool such…

  13. Allow EventFrame("Duration") to be used as an EndTrigger

    I want to stop my Event Frame after an amount of time that is stored in an AF Attribute. For my use case, the amount of time from the beginning of an Event Fame is an end triggering condition. One way to do this, would be to allow the EventFrame("Duration") function to be used as an end trigger.

  14. Expand PI Point Array DR functionality: Source Units

    Currently, the PI Point Array data reference allows the Source Units field to be set, but this setting applies to all points in the array. It would be better if the Source Units field could be set individually for each point in the array for conversion to the Default UOM.
    Use case: we have multiple PI Points we want to put into an array, but some have source units of lb/h while others have source units of klb/h. We would like to enter the source units individually so all values in the array are converted to the same UOM (klb/h).

  15. Allow Asset Analytics to Evaluate functions for questionable flagged values

    Data can be flagged as questionable, which should mean the value may or may not be valid. Asset Analytics seems to be rejecting the value as Bad. The function instead should evaluate the result, but flagging the result as questionable as well.

  16. Add Process Capability Statistics fundtions (Cpk, Ppk)

    While it is possible to manually calculate Process Capability Statistics, such as Cpk and Ppk, using AF Asset Analytics, it would be much more convenient to have a built in function to calculate these values, specifically in relation to the SQC Western Electric rules analyses available in AF asset analytics already.

  17. New AF analyses should be automatically backfilled a set time interval upon creation.

    There should be an option in PSE to automatically backfill all AF Analyses a set time interval upon creation that can be set once. This would prevent a user from having to manually backfill analyses individually or in a group from the Management pane each time new analyses are created.

  18. Setting to send email notification to all subscribers on one email

    I believe this has been requested before by someone but I can't find it so I am submitting a new feedback/request. It would be very useful if there was a setting for PI Notifications that would allow for sending emails to all subscribers on a notification rule in a single email instead of sending individual emails to each subscriber. For example, if there was a setting that would allow sending one email for a notification rule with all subscribers on the "TO" line that would allow users on the email notification to see who else received the alert and provide…

  19. Option to install sample PI tags with simulator interfaces

    Posted on behalf of a customer.

    As of PI Server 2018 SP3, simulator interfaces have been removed from the PI Server setup kit, and the default PI Points are no longer installed. These were very important to check if the server installation went well. I like to have options in the PI Data Archive install kit to install sample tags and simulator interfaces together with server component. This makes much easier to set up environment test.
