Tested in 3.9.13. Confirmed. My used to total heap percent was approximately 10%. Even setting the monitor to Threshold of 1 does not seem to cause the monitor event to show up in sym_monitor_event. Setting the Threshold to 0 does in fact cause the monitor to fire. Perhaps there's a scaling issue when going from Threshold value in the database to percent of heap used?

I think the monitor is returning the percentage of memory used as a decimal instead of an integer. When 30% of heap is used, it returns 0.30 instead of 30.

Memory monitor threshold now works with an integer based percent. So "60" for the threshold should fire when used when 60% of the allowed memory is used.
