Hi, we would like to set up an alarm to check data flow on every tag we have per interface. We have an alarm for system tags, but sometimes we are having issues with data flow outside of PI control, so we would like to set up an alarm to include a check on every tag. To do this I'm setting up an analysis on AF to say if this tag time stamp is higher than 2 hours from now (*) then return 1. We have thousands of tags and so I would need to add thousands of tags to the analysis. Is there an easier way to do this? Like for example to reference each point source for example? And how do we do it please? Many thanks.
