NameError (uninitialized constant MemoryTracker::Request::Sys):

[okliv]

just after including gem into gemfile i receive this error...

if i add

 require 'pp'
 require 'sys/proctable'

to gems/memory_tracker-1.2.2/lib/memory_tracker.rb

i receive next errors

 undefined method `rss' for #<Struct::ProcTableStruct
 undefined method `vsize' for #<Struct::ProcTableStruct

for this block of code in memory_tracker-1.2.2/lib/memory_tracker/request.rb

private

def self.rss
  rss = ProcTable.ps(Process.pid).rss * 0.004096
end

def self.vsize
  vsize = ProcTable.ps(Process.pid).vsize * 0.000001
end

and as far as i discovered ProcTable.ps... really has no this methods https://github.com/djberg96/sys-proctable/wiki

is this gem ready for production? can you please help to run it properly? because looks like very nice instrument to monitor memory leaks

i have replaced require 'sys/proctable' with require 'ps' (gem 'ps') and edited request.rb here

private

def self.rss
  rss = PS.pid(Process.pid).first.rss / 1024 #* 0.004096
end

def self.vsize
  vsize = PS.pid(Process.pid).first.vsize / 1024
end

and now it shows something as expected (still not sure if info is true but looks like)...

also, i found an error in env.rb:10

 request = Rails.application.routes.recognize_path(env['REQUEST_PATH'], routes_env)

has to be replaced with

request = Rails.application.routes.recognize_path(@path, routes_env)
