  1. Replace the batch (.bat) scripts in the %PISERVER% folder with PowerShell (.ps1) scripts

    This replacement is appropriate for several reasons:
    • PowerShell is easier to read and is a more powerful language than the batch language.
    • Batch scripts are best used in Windows, whereas PowerShell is cross-platform. This replacement will support OSIsoft's expansion outside of Windows.
    • Microsoft is pushing for PowerShell and leaving batch files in the dust. Ideally, PI systems would not rely on legacy technology.

  2. PI Data Archive Installation Wizard should provide an option to restore from a backup or copy current configuration from another PI Server

    As we enter 2020, the process of moving/restoring the PI Data Archive hasn't changed since its inception. Typical procedure to move a PI Data Archive on a new server is to install same version of software and then perform backup/restore of the old server. The process can be simplified if the installation wizard provides an option of whether this is a new installation or rebuilding of an existing server. This eliminates unnecessary install of out of the box configuration just so that the files be overwritten later. Wizard should provide options of overwriting license file, paths to archives and queues…

  3. smarter calculation of PI Backup required free space

    When backfilling tags from AF its very easy to update many archives. I would like the backup script to only require free space for archives that don't exist in the target folder. We have periodic incremental backup failures do to a lack of free disk space, even though almost all of the archives being backuped up will replace files that already exist in the target folder

  4. Ability to store metadata information for PI data

    For forecasts, probabilities are assigned to each forecast data. It would be helpful to be able to store this information (metadata) for each forecast value.

  5. Have the ability to change PI Message log file configuration (Size, Duration etc)

    If verbose logging is setup for applications such as (PI Batch) which write to the PI message log (or if you have very busy PI servers with lots of logs), the file sizes can get to several GB in size. It would be good to have the ability to configure the log file size

  6. Repeatedly loop future data

    Customer would like to be able to loop future data.  For instance since yearly temperatures are about the same every year for a given month, it would be nice if only one set of the projections are stored somewhere and just repeated again and again every year.

  8. Backup pre-commited

    As a Pi Admin, it would be usefull to be able to locate the Precommit directory used during the PI backup process to a different location from the Backup directory

  9. Compression Standards

    The ability to define and rollout compression standards on tags across the enterprise / sites. 

    When this information is captured bottom up from sites, bad settings make it difficult to maintain a standard which inhibits cross site data comparisons.

  11. Provide mechanism to assist in Kerberos configuration / delegation testing

    As a PI Admin, I need assistance configuring and testing Kerberos delegation, so that I can access the full functionality of the products without exposing my system.

  12. Have an option to use step interpolation to the previous event

    When the Step attribute of a PI Point is "on", PI assumes that a value is constant until the next event, which works well in most cases.

    For PI Points that track rolling averages, rolling totals, real-time derivatives of totalizer tags with respect to time, etc., it would be more useful to assume that a value is constant up to the previous event. Please add this as an interpolation option for PI Points.

  13. 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.

  14. Compress archives that are backed up using "Copy"

    Currently, when a "copy" backup occurs, the archives are copied as-is. Archive files take up a lot of space, but they also compress very well, and since archive backups are rarely accessed, it makes sense to trade off increased access time (due to the additional work of decompression) to get a smaller file size for the archive backups.

    The exact method of compression (new file format, put archives in a compressed folder, etc.) will be up to OSIsoft. In my testing, I used disk compression on the archive files.

  15. Allow edited default tag attributes to be used in Point Builder SMT Plugin

    Currently there is a procedure that allows using piconfig to Change Default Tag Attributes however these changes do not impact the defaults of tags created through Point Builder plugin within SMT but works on other clients that allow tag creation such as PI Builder.

    This request is to allow SMT to accept these Tag default changes to be reflected on tags created through PI SMT

  16. Dictionary encoding of strings in string tags

    Currently, the values of string tags are stored in full for each event, which is a waste of space for string tags that have the same values appearing frequently. To save space, please use dictionary encoding (AKA dictionary coding or dictionary compression) to store the values of string tags. The space saved for string tags that have many repeated values should hopefully offset the extra space used for string tags that have mostly unique values.

  17. Dynamic digital state sets

    Currently, the values of string tags are stored in full for each event, which is a waste of space for string tags that have the same values appearing frequently. To save space, a digital tag can be used instead. However, to create this tag's digital state set, we must know ahead of time all possible strings that the tag may store, and this may not be possible or feasible.

    My suggestion is to introduce dynamic digital state sets. That is, tags using dynamic digital state sets would receive strings from the data source. If the string is not already part…

  18. Provide the user ability to select Event Frame templates during the Batch to Event Frames Migration

    During the Batch to Event Frames Migration, all migrated Event Frames are created with 'Migrated' templates (i.e. PIBatchMigrated, PIUnitBatchMigrated, etc.). I would like the ability to pick and choose what templates migrated Event Frames are created with.

    As some background, Batch Interfaces currently use a standard set of EF Templates -- 'Procedure' template for the top level Event Frame, 'UnitProcedure' template for the first child level, etc. I would like to assign these default templates to Event Frames created by the migration process. This will ensure perfect continuity between migrated Event Frames and future Event Frames created by any Batch…

  20. Digital State Sets and Bit Flags

    a common data type encountered are Double Integers as bit flags, where different combinations of each bit of the binary representation of the double integer corresponds to a state. PI's Digital State Sets do not handle these well.

    First, it requires that even unused states are created in the set . . . annoying, but not a total hindrance (there is another idea posted pertaining to this particularly)

    Second, digital state sets have a maximum of 16383, which is only 14 bits, which is only sufficient for single integer (8 bit) flagging techniques.
