Real Time Snapshot Support
PI System Connector: Need real time snapshot data support for the PI System connector.

shared this idea
This item is under technical review. Currently, support for collecting Snapshot data can be achieved via PI to PI interface and should be considered for achieving this specific functionality.

This is really important in our infrastructure. Is there an update on the status of this enhancement request?

Can we get any official statement if this will be implemented at all? It is in "Research / Evaluating" now for more than ONE year...

This snapshot support is important for our company to decide and move from Pi2Pi to SC. We are using global applications with Umetrics and some OEE tools requiring snapshot. The SC will bring a lot of value but keeping the 2 tools working together is not envisioned.

We need the support as well for a lot of analysis and decision making projects. We have already got a lot of requests from our customer.

Now we need to support multiple tools to sync systems: PI2PI and System connector. Moving to a single tool will reduce overall ownership cost.

Without snapshot support, none of my customers will consider using the tool. Snapshots are required for all Analysis and decision making

Using a historian and it's related tools, it is obvious to get the data real-time. I had no idea System Connector does not support this and it's always a value behind. We are having so much issues especially with Digital, manual entry PI points where OSIsoft recommended to use both Connector and PI to PI. I VOTE!

This topic is already under Research/Evaluating. Is there a new status? It's really important to get this support. Use of additional tools like PI Cloud connect, PItoPI interface,... is not straightforward and not in scope of best practice for an state of the art IT Architecture.

It is misleading to brand this product a "PI System Connector" without support for snapshot since it is one of the most fundamental subsystems.

Hey Matthew, really? So the System Connector team now plans on supporting snapshots? If they do that, give it a more full featured history recovery GUI, and allow for choosing archive modes then maybe it could replace PItoPI. I was disappointed with several aspects of System Connector but I did see some benefits: One-way firewall rules, seamless PI tag attribute sync, and more resilient to network issues (since using SDK vs API tech). I'm happy they're considering supporting snapshots though, that's vital. -

Couldn't agree more! -

I had heard the same thing, but I've also recently heard they've re considered. -

PI to PI in parallel is not a solution. i expect to have one tool to communicate from a local system to a global system. there should be a straight forward way to connect one PI System to another and not different combinations of tools. another reason, the communication from local to global should be secured (it's with the connector, but not with PI to PI). so the connector should be able to:
-communicate historical data based on archive
-communicate snapshots in real-time mode
-full AF/EF support -

PI to PI and APS is still not meeting our requirements. While OSIsoft says this is the solution, its not a good one. PI APS processes tags one at a time. Startup time for PItoPI is also slow. APS and PItoPI is not multithreaded. The APS syncing for a large amount of tags is not meeting our need. Because the Connector still does not meet our requirements, we've had to add many (currently 14) interfaces which is very difficult to manage across multiple servers at multiple locations. Anytime we have PI to PI or APS talking to systems at other locations (for disaster recovery) latency causes the startup time and sync times to take hours. Not an acceptable high availability solution.

With 47 votes you would think the folks would listen to what we need. I have not been impressed with how slow this connector has been moving. APS and PItoPI are not working for us. Syncing a collective across a few states, causes latency issues and the sync process takes 24 hours currently.

I wouldn't get your hopes up. I received an update on this on January 4, 2019 from a connectors product specialist at OSI. He reached out to the product manager for System Connector and they have decided not to support snapshot data collection with PI System Connector. On hearing this news my org has decided to remove System Connector and go with PItoPI/APS instead. The PI System Connector seems like a half-baked solution right now. I've heard from OSI that it should not be seen as a PItoPI replacement (see here) but instead should be seen as a solution for migrating AF DB structure from one AF environment to another. However, as of now, System Connector doesn't support migrating Analyses or Notifications. I have to say that System Connector seemed to handle PI tag creation/updates a lot more seamlessly than APS but also there was much less control and customization. With time I'm sure System Connector will become a solid product but seems lacking as of now. -

I should add that we have been waiting for the connector to meet these requirements for 4 years!
Essentially we want two collectives ( a source and destination) to be the same.
Requirements
- Send PI data even if it's not in AF.
- Send real-time snapshot data. It seems really useless for us to be able to only send archive data. Users using the destination system don't get the real-time or accurate values? A breaker is closed, but the users see's it open? Not making sense.
- If a tag name is changed on the source collective, it should update on the destination side.
- Should be much faster then PI to PI and APS (multi threaded), should work better across two locations where latency comes to play.
- Should be easier to configure then PItoPI and APS -

We need this as well. We have a project on hold until this is done.

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.
