  2. Write a description for the PI Data Archive services

    When you open the Services program (services.msc), none of the PI Data Archive services have a description. Please provide descriptions for these. The specific services are:
    • PI Archive Subsystem
    • PI Backup Subsystem
    • PI Base Subsystem
    • PI Buffer Subsystem
    • PI License Manager
    • PI Message Subsystem
    • PI Network Manager
    • PI Shutdown Subsystem

  3. 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

  4. 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.

  5. Provide the capability to apply compression on uncompressed data, aka recompress using offline archive utility.  See work item 6944OSI8.

  6. RDBMS Interface - Full Sync and Annotations

    The PI SDK writes required for setting annotation values with the exdesc and RDBMS interface are not compatible with Full Synchronization.

    Make this compatible.

  8. Ability to Identify Critical (e.g. GxP) PI Tag in SMT

    A checkbox or some mechanism to identify Critical data point (e.g GxP) in SMT.
    * can be used for search filter to separate critical vs. non-critical data (gxp vs non-gxp)
    * possible additional layer of confirmation/prompt prior deletion (?)
     
    Current workarounds :
    using prefix/suffix to flag critical data point,using point source to separate,creating logical categories in AF, etc.

  9. Use of aliases for tag names

    Allow the creation of tag name aliases.  This would allow us to present more user friendly option for tag name searches.  It would also help present a standardized tag name to users for tags from sources that don't follow our standard tag naming conventions.

  10. Ability to view Instrument Tag and Point Source attributes within PI SMT > Data > Current Values pane

    Feature request would be to include Instrument Tag and Point Source attributes to be view-able through the Data > Current Values pane of PI SMT.  This would allow administrators and users the ability to quickly diagnose and/or trace PI Points from a centralized location.

  12. PI collective with shared archives

    Allow the Primary Data Archive server read-write access to any shared archives. All Secondary data archive servers would have read-only access. This would fix case Case # 925881. We have tags with old timestamps, for example, environmental limits, that don't update very often. If the current value timestamp falls within the range of archives moved to shared storage and the limit is updated, the current value would be lost since currently archives shared in HA must all be read-only.

  13. Having different sets of Archive Files.

    Having different sets of Archive Files or "how to Define Archive for the Tags Individually". For example sending the Process Data to a different Archive File than the Building Monitoring Tags.

  14. 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?

  15. Store multiple events at the same timestamp

    I have a particular application for storing partial discharge events into the PI Server.  Many of the events are at the same timestamp, which result in multiple events at the same time.

  16. 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…

  17. Apply correct localhost.tz file during PI Data Archive installation

    To account for the different historical implementations of Daylight Saving Time in different regions, a localhost.tz file is added to the %piserver%\dat directory after installation. As an installer of PI Data Archive, I would like the localhost.tz files to be incorporated into the PI Server install kit, and to have the install kit either automatically select the localhost.tz file based on the machine's time zone settings, or allow me to manually select. This would eliminate a very manual step of PI Data Archive installation that is often forgotten.

  18. 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.

  19. 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.

  20. 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.
