利用Nginx日志进行流量预测可以通过以下几个步骤进行:
argparse库来处理命令行参数,并读取和分析日志文件。以下是一个简单的Python脚本示例,用于统计每小时内的流量:
#!/usr/bin/python3 import time import os import sys import argparse class displayFormat(): def format_size(self, size): KB = 1024 MB = 1048576 GB = 1073741824 TB = 1099511627776 if size >= TB: size = str("%.2f" % (float(size / TB)) ) + 'T' elif size < KB: size = str(size) + 'B' elif size >= GB and size < TB: size = str("%.2f" % (float(size / GB))) + 'G' elif size >= MB and size < GB: size = str("%.2f" % (float(size / MB))) + 'M' else: size = str("%.2f" % (float(size / KB))) + 'K' return size def execut_time(self): print('\n') print("Script Execution Time: %.3f second" % time.time()) class input_logfile_sort(): def __init__(self): self.read_logascii_dict = {} self.key = 1 def logascii_sortetd(self, logfile): with open(logfile, 'r') as file: for line in file: data = line.split() timestamp = data[3] + ' ' + data[4] + ' ' + data[5] size = int(data[6]) self.read_logascii_dict[timestamp] = size sorted_data = sorted(self.read_logascii_dict.items(), key=lambda x: x[0]) return sorted_data if __name__ == "__main__": parser = argparse.ArgumentParser(description='Nginx log analyzer') parser.add_argument('-f', '--logfile', help='Path to the nginx access log file', required=True) parser.add_argument('-m', '--minutes', type=int, default=60, help='Time interval for traffic statistics in minutes') args = parser.parse_args() display = displayFormat() sorter = input_logfile_sort() sorted_logs = sorter.logascii_sortetd(args.logfile) start_time = sorted_logs[0][0] end_time = start_time total_traffic = 0 for timestamp, size in sorted_logs: current_time = timestamp if current_time != end_time: end_time = current_time print(f"{start_time} - {end_time} <====> {display.format_size(total_traffic)}") total_traffic = 0 total_traffic += size print(f"{start_time} - {end_time} <====> {display.format_size(total_traffic)}") display.execut_time() 。
通过上述步骤,可以实现对Nginx流量的实时监控和预测,帮助系统管理员更好地理解和预测流量变化,从而做出相应的资源分配和负载均衡决策。
