I have a future data tag that is getting updated every 15 seconds. How can i trace the source of this write? I have tried pibufss -trace <pointid>, but never see a value. Looking at the server, I tried to determine the Buffer Source, but the piartool -sd \<pointid> did not return a Buffer Source as described in the KB00093 in the Compressed Event (it just returned the point value). I also tried dumping out point for each Buffers Source that showed up in piartool -bfs, however the point did not show up. Is there any other mechanism to help trace the source of a write?
