Virtual Memory Graph




This Sensor shows Virtual Memory usage in percents. Total Virtual memory is nearly sum of RAM and swap files maximum sizes. See description of data on the Sensor below.


   Vrt=33% -- Last time sampled Virtual Memory usage is 33%.

   Other 24 -- Percent of virtual Memory Pages in RAM plus Pages that were allocated but not touched (not exist). When Application allocates memory, System allocates really only range of addresses. Real Page created when application code first time read or write some address belonging to this page. Still sum of all allocations can not be more than Total Virtual Memory or so called "Commit Limit".

   Swap 9 -- Percent of Virtual Memory Pages swapped out to Swap Files.
