comment non-mapped virtual memory & total number of connections
if you give me the group name in MMS, I can take a look (I work for 10gen). Other things that should be looked at are readahead when you are dealing with memory allocation: serverfault.com/questions/408100/… and serverfault.com/questions/418352/…

comment How to get the MongoDB' current working set size
Generally the resident figure on the memory graph is the most relevant here. It will grow over time and occupy all available RAM (with older data paged out as needed for new data to be paged in) if your data set is significantly larger than RAM. If not and the data set is fairly static, it will find a lower level and hover there. The Max value I outline above would be the most RAM an individual database would take up as part of that figure.
