Does anyone know how I can identify if the Compression Insight is on for the tags?
And how often this compression Insight is run?
Are you talking about CompressionInsight the application by one of our partners? If so, with my limited understanding of the application, there is no record stored in the Data Archive of the application having been ran and its recommendation applied to a particular tag. If it is indeed a question related to CompressionInsight it might be best to ask them directly about it http://patterndiscovery.com/contact/
Just to clarify, are you talking about exception and compression where the data that will be archived is minimised to reduce disk space usage without compromising the integrity of the trend/data?
To check if the compression is on for the tags, you can check using PI SMT (System Management Tool). In SMT, connect to PI Data Archive and on the navigation pane, go to Points > Point Builder. Load the tag you are interested in, and select the Archive tab; within this tab, you will see the settings for "Compressing" and "Compression Devation".
If you're talking about something else, sorry about that but do let us know more about it.
