Display number of bytes in data set - ruby

Question

I wrote a program to create histograms of IP addresses, URLs, error codes, and frequency of IP visits, and would like to obtain the size, in bytes, of the data collected for each histogram. I looked around and saw a bit about the bytes method, but can't seem to get it to function.
Any idea on how to do that to this bit of code? I'd like to add the "byte puts" line after displaying the filename in each method.
class CommonLog
def initialize(logfile)
#logfile = logfile
end
def readfile
#readfile = File.readlines(#logfile).map { |line|
line.split()
}
#readfile = #readfile.to_s.split(" ")
end
def ip_histogram
#ip_count = 0
#readfile.each_index { |index|
if (#readfile[index] =~ /\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}/ )
puts #readfile[index]
puts #ip_count += 1
end
}
puts File.basename #logfile
end
def url_histogram
#url_count = 0
#readfile.each_index { |index|
if (#readfile[index] =~ /\/{1}(([a-z]{4,})|(\~{1}))\:{0}\S+/ )
puts #readfile[index]
puts #url_count += 1
end
}
puts File.basename #logfile
end
def requests_per_hour
#time_count2 = 0
#time_count3 = 0
#time_count4 = 0
#time_count5 = 0
#time_count6 = 0
#readfile.each_index { |index|
if (#readfile[index] =~ /\:\d{2}\:/ )
#new = #readfile[index].split(":")
if #new[1] == "02"
#time_count2 += 1
elsif #new[1] == "03"
#time_count3 += 1
elsif #new[1] == "04"
#time_count4 += 1
elsif #new[1] == "05"
#time_count5 += 1
elsif #new[1] == "06"
#time_count6 += 1
end
end
}
puts "#{#time_count2} instances during hour 2"
puts "#{#time_count3} instances during hour 3"
puts "#{#time_count4} instances during hour 4"
puts "#{#time_count5} instances during hour 5"
puts "#{#time_count6} instances during hour 6"
puts File.basename #logfile
end
def sorted_list
#codearray = Array.new
#http_code_count = 0
#count200 = 0
#count304 =0
#count301 = 0
#count403 = 0
#readfile.each_index { |index|
if #readfile[index] =~ /([2][0][0]")|([3][0][4])|([3][0][1])|([4][0][3])/
#codearray << #readfile[index]
#http_code_count += 1
if #readfile[index] == '200'
#count200 += 1
elsif #readfile[index] == "304"
#count304 += 1
elsif #readfile[index] == "301"
#count301 += 1
elseif #readfile[index] == "403"
#count403 += 1
end
end
}
#hash_count = 0
#frequencies = Hash.new(0)
#codearray.each { |word| #frequencies[word] += 1 }
#frequencies = #frequencies.sort_by { |a, b| a}
#frequencies.each { |word, frequency| #hash_count += frequency}
#frequencies.each { |key, value|
puts "Error #{key} : #{(value.to_f/#hash_count.to_f)*100}%"
}
puts File.basename #logfile
end
end
my_file = CommonLog.new("test_log")
my_file.readfile
my_file.ip_histogram
my_file.url_histogram
my_file.requests_per_hour
my_file.sorted_list

Answer 1

Assuming that the number of bytes processed is the entire size of each log file you could do something like this:
class CommonLog
attr_reader :bytes_read
def initialize(logfile)
#logfile = logfile
#bytes_read = File.size(logfile)
end
# ... now simply print "bytes_read" when desired ...
