私はpythonファイルを持っています。私はログファイルとurlをコードに渡します。出力ファイルには、URLがどのIPアドレスでアクセスされたかが含まれます。特定の日付にpingされるipsの数を調べる方法は？
#!/usr/bin/env python
#
# Counts the IP addresses of a log file.
#
# Assumption: the IP address is logged in the first column.
# Example line: 117.195.185.130 - - [06/Mar/2012:00:00:00 -0800] \
# "GET /mysidebars/newtab.html HTTP/1.1" 404 0 - -
#
import sys
def urlcheck(line, url):
'''Checks if the url is part of the log line.'''
lsplit = line.split()
if len(lsplit)<7:
return False
return url==lsplit[6]
def extract_ip(line):
'''Extracts the IP address from the line.
Currently it is assumed, that the IP address is logged in
the first column and the columns are space separated.'''
return line.split()[0]
def increase_count(ip_dict, ip_addr):
'''Increases the count of the IP address.
If an IP address is not in the given dictionary,
it is initially created and the count is set to 1.'''
if ip_addr in ip_dict:
ip_dict[ip_addr] += 1
else:
ip_dict[ip_addr] = 1
def read_ips(infilename, url):
'''Read the IP addresses from the file and store (count)
them in a dictionary - returns the dictionary.'''
res_dict = {}
log_file = file(infilename)
for line in log_file:
if line.isspace():
continue
if not urlcheck(line, url):
continue
ip_addr = extract_ip(line)
increase_count(res_dict, ip_addr)
return res_dict
def write_ips(outfilename, ip_dict):
'''Write out the count and the IP addresses.'''
out_file = file(outfilename, "w")
for ip_addr, count in ip_dict.iteritems():
out_file.write("%s\t%5d\n" % (ip_addr, count))
out_file.close()
def parse_cmd_line_args():
'''Return the in and out file name.
If there are more or less than two parameters,
an error is logged in the program is exited.'''
if len(sys.argv)!=4:
print("Usage: %s [infilename] [outfilename] [url]" % sys.argv[0])
sys.exit(1)
return sys.argv[1], sys.argv[2], sys.argv[3]
def main():
infilename, outfilename, url = parse_cmd_line_args()
ip_dict = read_ips(infilename, url)
write_ips(outfilename, ip_dict)
if __name__ == "__main__":
main()
は今、私は、URLの代わりに日付を渡した場合、出力ファイルは、その特定の日にpingを実行しているすべてのIPが含まれている必要がありますようにコードを変更したいです。
ログファイルの形式は次のとおりです。
