Using the new Passenger Monitor plugin, Scout can keep track of Passenger’s VM size, process count, and the amount of private memory it has squirreled away. Aside from just tracking these numbers for graphs, you can also elect to be emailed if any of these statistics crosses a line you indicate. As an added bonus, this plugin also tracks the same statistics for the Apache instance managing Passenger.
Passenger has quickly become a great new way to deploy Rails applications and we want to make sure Scout is keeping up with the curve.
