  1. Incremental backups are not possible because of frequent backfilling

    Occasional back filling of data would cause 5 TB of archives to be backed up with incremental backups. This is frustrating because only a few KB of data is changed in each archive. Can OSIsoft provide a way to backup only the data that has changed or support a 3rd party backup solution that would backup only the differences?

  2. PI Archive ability to recover from drive disconnect

    With everyone having virtual servers these days the host VM and SAN storage are on separate devices. When the storage device is unavailable or disconnected even briefly, the PI Archive process errors and gets DISABLED and can ONLY be restarted by a manual restart of the PI Archive Subsystem. You will see Snapshot updates since the VM is still running fine, but nothing gets into or out of the Archives.

    The requested enhancement is for the Archive Subsystem to be able to recover from this situation on its own.

    Here is the error message you will get when this happens…

  3. Wave Form Data Collection

    A few customers would like the capability of storing vibration wave form data in PI. They often measure data in MHz and GHz frequencies, which are at a finer resolution that the PI Data Archive is capable of storing. The wave forms are captured over periods from 2 to 30 seconds and only saved if there is an interesting event.

    Customers in data centers are also requesting power quality wave form storage in PI.

  4. Buffer subsystem to handle deleted values

    Can buffer subsystem be enhanced to manage value deletions from tags? We have a collective and utilize buffering to send data to both collective members however we have to jump through hoops to delete data from both collective members. It would be nice if the buffer subsystem could handle value deletions just like how it handles all other value adds and replacements.

  5. PI Archive File header should keep track of last modified recno

    The PI Archive File should keep track of the last modified RecNo. This would make cases where historical archive last modified times are updated (and potentially causing large backups) much easier to track down.

    In particular, this feature combined with the new Snapshot_TracePointID tuning parameter in PI Data Archive 2017+ would make figuring out what is updating archive last modified times much more straightforward.

  6. Support User Information in Connection History Tool

    (pidiag -connectionhistory)

    Support the collection and retrieval of PI / Windows user information by the connection history database.  

    Currently, the connection history database only stores IP addresses which can be misleading when multiple multiple users work from the same computer.

  7. Undelete PI tags

    Recovering a PI tag that was deleted accidently is extremly annoying.
    Why do I have to create a new tag and reprocess all historical archives to convert the old tag to the new tag in the archives? (https://techsupport.osisoft.com/Troubleshooting/KB/2651OSI8/)

    It should be quite easy to just recreate the original tag if you have the pointid and recno. Maybe when deleting a tag you should only mark the tag as deleted instead of removing it from the pi point table.

  8. New attribute for a PI point type ID

    To take full advantage of AF and substitution parameters it would be great to have a sort of type ID. Now i have to rename all tags to gain this possibility. It would be easy if i could use a portion of the tag name and a  type id. Then i could deploy AF templates with substitution parameters really fast.

  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.

    This is currently possible by leveraging AF. In AF, you can configure a template with the desired PI Point attribute configurations, then you can exercise the “Create or Update PI Point” option to change the PI Point attribute.

  10. Force Shift warning is misleading

    When force shifting an archive, the following message is displayed:

    "Warning: This shift will clear data from the target archive. Are you sure you want to force an archive shift on <serverName> to a new archive?"

    When Auto Archive Creation is enabled (having a value in Archive_AutoArchiveFileRoot), this is very misleading. A new archive will be generated and no data will be wiped.

    This warning should only display if auto archive creation is not enabled and the archive will shift into the oldest shiftable archive.

  11. pisrvstart and pisrvstop scripts should have pilogsrvX64

    pisrvstart.bat and pisrvstop.bat scripts should have "pilogsrvX64" added to them.  Currently all services except the "PIPC Log Server x64" are started/stopped by these scripts.

    This log service is used by 64 bit application that loads the PI API. The most common being 64 bit PI Interfaces. Therefore if you have 64 bit PI API based applications, these scripts should start/stop the service for you. Please contact tech support if you have these applications and pilogsrvx64 is not in your pisrvstart and pisrvstop scripts.

    As a side note, recent releases of the PI Server implements virtual service accounts for all the Data Archive related services so please consider it for an upgrade.

  12. Make it easier to get a list of buffered or unbuffered points on the PI Data Archive

    For PI System Administrators, it would be nice to be able to easily get a list of all buffered or unbuffered points on the PI Data Archive.

    Currently, a list of buffered points is possible to retrieve using 'piartool -bfs <id> -ptlist', but a comprehensive list would require iterating through all of the buffered sources.

    Such functionality would be nice because it would allow administrators to easily identify which data sources need to be configured for buffering, or which data sources are possibly misconfigured for buffering. It would also be a quick thing to check for points which may potentially…

  13. PI Data Archive - Data Share - Distributed, Scalable, Load Balanced

    OSI should get together and devise a proper data synching mechanism that should guarantee synching archives for all backfilled events and so on.

  14. As a PI Administrator, we should be able to see which PI mapping was used for a Windows AD user in PI message logs.

    Through PI message logs I want to see which PI mapping was used for a Windows AD user, currently only the PI identity associated the windows AD is visible in the Logs. PI mapping information will give us more idea/facts about the particular Windows AD user.

  15. Add Access Right that Allow Users to Create Tags But Not Delete Tags

    As a user of the PI Data Archive, I would like the ability to give users access to create tags but not to be able to delete tags. This way they will not be able to accidentally delete tags but they still have the ability to create tags.

  16. Add new PIPointAttribute for "StaleTimeout"

    While no customers have asked for this directly, I have seen many customers ask how to check a tag for being stale. The solution to date assumes all tags have the same staleness timeout, which really is not the case most of the time.

    This new "StaleTimeout" point attribute would be a duration (time span) customizable for each tag. There could also be a new PIPoint property called "IsStale" which could bounce the current value's timestamp off the "StaleTimeout".

  17. 64-bit Unix time

    Consider upgrading from 32-bit Unix time to 64-bit Unix time so that PI can support dates past January 19, 2038. Reasons:

    1. This date is fast approaching as a future value. It is only 20 years away.

    2. OSIsoft will need time to implement the 64-bit time stamps and convert all existing and supported PI Data Archives to use the 64-bit time stamps. At least a year of time will be used up for leeway.

    3. Once 64-bit Unix time is implemented, then OSIsoft can exclude from training presentations the (very high) upper limit of supported time. This gives the user 1 less…

  18. Archive Reprocessing Backup

    The current automated Archive reprocessing creates a backup of the original archive in the archive directory. This can lead to a situation where the archive drive runs out of space.

    It would be useful to be able to configure the backup location for the reprocessed archives. This should be a tuning parameter.

  19. Support different data retention policies

    As an administrator, I need to ability to configure the life span of my PI data, so that data are kept or deleted accordingly. For example, data that should be deleted based on corporate mandates and data that should be kept forever are handled accordingly.

    Note: This was previously Enhancement 25774OSI8.

  20. Ensure data is identical between collective members

    As a PI Administrator, I need to trust that the data is identical between my collective members. Currently, there is no way for me to be sure it is the same unless I do a side by side comparison. Data can be missing, or slightly off, and I have no easy way to understand this right now.
