Real Time Snapshot Support
PI System Connector: Need real time snapshot data support for the PI System connector.
We will soon be moving forward with the addition of Snapshot support for PI System Connector. I look forward to continuing to update you once we move from planning to active development work on this enhancement.
In the meantime, please continue to share your comments regarding Snapshot support for PI System Connector here.

I heard that this feature is in the works. Is there a tentative timeline for this? Like everyone else here, I agree that this is a very necessary feature.

Another vote for this functionality. We replicate data from remote site PI servers to a central enterprise server - having snapshot data available here to trigger real-time alarms is critical. Without this functionality, we are unable to implement PI System Connector at this time.

Another example: One of my customers has a situation where manually entered data or KPIs are calculated on a daily basis, or even hourly. The snapshot value won’t get to our central server till the next hour/day/etc. I don’t think there is a way to force the value to automatically go from snapshot to archive. PI always needs the current value and the previous value to decide if it needs to archive. Therefore, they need the snapshot value to be included in the PI System Connector.

This idea is very important, Tood. Thanks for sharing.
I would like to mention is a typical use:
- Daily KPIs are calculated at the source system, and they should be available immediately on the destination server as soon as they get calculated in the source.
Unfortunately, with the current implementation of PI System connector, we see a lag of 1 day between the last daily result available in the destination PI System and the one available in the source PI System. One of my customers is having this issue right now.
A must have if replicating to an enterprise server that is then used as the primary source of data for end users.
