A simple gem to dump memory stats. Primarily written to tick off the "I wrote a gem" box. I'll probably improve it to be some kind of analyzer/profiler if time permits. Suggestions welcome!
Add this line to your application's Gemfile:
gem 'quick_mem'And then execute:
$ bundle
Or install it yourself as:
$ gem install quick_mem
require 'quick_mem'
# show memory stats (more-or-less raw form)
QuickMem::QuickMemory.show_stats
# show memory summary (heap total,used,free mem in MB and percentage)
QuickMem::QuickMemory.show_summary
# view top 50 objects by descending order of size
QuickMem::QuickMemory.view_objects_by_size
# view top 50 objects by descending order of instance count
QuickMem::QuickMemory.view_objects_by_count- Fork it ( https://github.com/rajivrnair/quick_mem/fork )
