  • old version used to look at Memstats.Sys, which was the entire virtual
    memory space, and effectively useless. Hence also why it's been hidden
    in the dashboard since forever. Most people expect this would
    look effectively at rss, so that's what we do now. + optional
    parameter to look at (only) the heap specifically
  • change default collection interval to 10s. That's what we've been
    running in prod for years without any issues.

Just the change for clarification already noted, other than that looks fine, but I haven't reviewed the library code from profiletrigger so I am unaware of all those changes. Would you like me to take a look at those?
