# profile.rb - A script that analyzes the memory usage of a redis instance from it's "dump.rdb"
#
# To run this script, edit the key_groups variable in the stats method, and then run
# `ruby profile.rb dump.rdb` in the command line.
# Running this script will:
# * Dump the contents of the input rdb file in CSV format to "/tmp/memory.csv"
# * Load the contents of "/tmp/memory.csv" to the table "mem" in the "redis_mem" database
# * Print the stats of each key group to STDOUT

# Haproxy config file for SSL and basic authentication

# Since ssl is needed, we need to use

# Also, haproxy version must be haproxy-1.5-dev19 or above.

# An example curl command that queryies pic-collage.com/api/collages/feed is
