PI Analysis Performance Checker

Currently PI Analysis Service has a built-in Statistics tool in PI System Explorer. It is able to show statistics regarding Evaluation and Calculation Lag as well as Skipped Evaluations and some other important information. PI System Explorer could run these statistics periodically and notify the user (in the Management tab or in the Analysis tab itself) whenever a PI Analysis has its parameters out of certain values (could cause a bad performance) So that the users could avoid performance issues more easily.

    With the introduction of PI AF Client 2018 SP3 Patch 4, users now have the ability to see if any of their analyses or calculation groups are in a bad state. While this is not directly alerting customers as is stated in the idea, we believe that this self service method to check analysis performance is an important step in easing the burden of managing analyses.

    We are aware of the need to provide PI Analysis Service performance information but it's unlikely we would do that in PI System Explorer. PI System Explorer does not have a persistent connection to the services and it's not a notifications tool. As with all operations in PI System Explorer, you need to refresh the client manually to get updates. Having said that, we have exposed additional PI Analysis Servicer run time information via the AF SDK in recent releases and hope to put together improved methods for users to track service performance.
