When you say "raise a monitoring with the last 144 data points" what do you mean?
Are you averaging these points, or are you posting an array, or something else?

Hi Mark,
Thank you! My ioc is indeed changing very fast -- triggered by some hardware at 720 Hz, then
every the 144th time I call the db_post_event method to raise a monitoring with the last 144 data
points. Somehow i just miss every the other monitoring. I tried to slow down the clock by 8 times,
it (camonitor) is still doing the same thing.
Best regards,
Dehong
