Getting OpenWRT router stats with ruby

username = 'root'
password = 'secret'

# Will parse returned JSON content

#
# Authenticate
#
# Also returns router's dashboard status information, i.e. 
# the info you see in the router 'Status -> Overview' dashboard
#
# Returned keys

## Available statistics

### Network traffic

# Data used by the graphs available in **'Status -> Realtime Graphs -> Traffic'** 
# Network traffic
#
# Returned data format: time, rx bytes, rx packets, tx bytes, tx packets
#
# Data sample:
# [
#   [1358095466, 1482617413, 101161697, 1420821587, 62541131],

# Do something with the data
pp parser.parse(r.body)

### System load

# Data used by the graphs available in **'Status -> Realtime Graphs -> Load'** 
#
# System load
#
# Returned data format: time, 1min load, 5min load, 15min load
#
# Data sample:
# [
#   [1358098335, 36, 40, 56],

### Connections status

# Data used by the graphs available in **'Status -> Realtime Graphs -> Connections'** 
# 
# Connections Status
#
# Returned data format:
#
# statistics: TIME, # udp connections, # tcp connections, # other connections
# connections: returns a Hash, self descriptive.
#
# TCP and UDP number of connections is always 0, looks like a minor bug in this
# version of OpenWRT (1.0)
# Data sample:
#
# {
#   "connections" => [
#      {"bytes"=>"746295",
#       "src"=>"192.168.1.4",

# connections_status does not return valid JSON apparently, fix it
r.body.gsub! /(connections|statistics)/, '"\\1"'
# Do something with the data
pp parser.parse r.body

### Wireless interface status

# Data used by the graphs available in **'Status -> Realtime Graphs -> Wireless'** 
#
# Wireless interface wl0 status
# 
# Returned data format: time, rate, rssi (signal strength), noise
#
# Data sample:
# [
#  [1358099217, 61650, 213, 167],
#  [1358099218, 61650, 213, 166],

# ]
#

# Do something with the data
pp parser.parse r.body

what if i don't have openwrt router and want to test these data.What should I do and how shall i write code for production.
