    通过psutil和rrdtool模块相结合绘制网卡网络流量

    实例代码：

    ./cretea.py

    #!/usr/bin/python
          import time
          import rrdtool
     
      cur_time=str(int(time.time()))
      rrd=rrdtool.create(    'Flow.rrd','--step','300','--start',cur_time,
                'DS:eth0_in:COUNTER:600:0:U',
                'DS:eth0_out:COUNTER:600:0:U',
                'RRA:AVERAGE:0.5:1:600',
                'RRA:AVERAGE:0.5:6:700',
                'RRA:AVERAGE:0.5:24:775',
                'RRA:AVERAGE:0.5:288:797',
                'RRA:MAX:0.5:1:600',
                'RRA:MAX:0.5:6:700',
                          'RRA:MAX:0.5:24:775',
                'RRA:MAX:0.5:444:797',
                'RRA:MIN:0.5:1:600',
                          'RRA:MIN:0.5:6:700',
                          'RRA:MIN:0.5:24:775',
                          'RRA:MIN:0.5:444:797')
          if rrd:
             print(rrdtool.error())

     

                                                                    

    ./update.py

    import time,psutil
           import rrdtool
     total_input_traffic=psutil.net_io_counters()[    1]
     total_output_traffic=psutil.net_io_counters()[    0]
     starttime=int(time.time())
     update=rrdtool.updatev(    '/root/Scripts/rrdtools/Flow.rrd','%s:%s:%s' % (str(starttime),str(total_input_traffic),str(total_output_traffic)))
           print(update)
     

     

     

    ./graph.py

    import time,psutil
    import rrdtool
     

     

    title="Server network,traffic flow ("+time.strftime('%Y-%m-%d',time.localtime(time.time()))+")"
           rrdtool.graph("Flow.png","--start","-1d","--vertical-label=Bytes/s",
           "--x-grid","MINUTE:12:HOUR:1:HOUR:1:0:%H","--width","650","--height","230",
           "--title",title,
           "DEF:inoctets=Flow.rrd:eth0_in:AVERAGE",
           "DEF:outoctets=Flow.rrd:eth0_out:AVERAGE","CDEF:total=inoctets,outoctets,+",
           "LINE1:total#FF8833:Total traffic","AREA:inoctets#00FF00:IN traffic",
           "LINE1:outoctets#0000FF:Out traffic","HRULE:6144#FF0000:Alarm value\\r",
           "CDEF:inbits=inoctets,8,*","CDEF:outbits=outoctets,8,*",
           "COMMENT:\\r",
           "COMMENT:\\r",
           "GPRINT:inbits:AVERAGE:Avg In traffic\: %6.2lf %Sbps",
           "COMMENT: ","GPRINT:inbits:MAX:Max In traffic\: %6.2lf %Sbps",
           "COMMENT: ","GPRINT:inbits:MIN:Min In traffic\: %6.2lf %Sbps\\r","COMMENT: ","GPRINT:outbits:AVERAGE:Avg OuT traffic\: %6.2lf %Sbps","COMMENT: ","GPRINT:outbits:MAX:Max OuT traffic\: %6.2lf %Sbps",
           "COMMENT: ","GPRINT:outbits:MIN:Min OuT traffic\: %6.2lf %Sbps\\r")
     

     

     

    实现TCP探测目标路由轨迹

    所需安装包:ImageMagick(转换图片格式工具),graphviz(绘制图形工具)

    通过scapy的traceroute方法查询到路由轨迹，然后调用graph()方法进行路由轨迹的绘制，中间调用ASN映射查询IP地理信息并生成svg流程文档，最后使用ImageMagic工具转换svg格式为png格式。

     

    import logging,warnings
          import sys,os,subprocess
          import time
     
      warnings.filterwarnings(    "ignore",category=DeprecationWarning)  

    #屏蔽scapy 无用信息
      logging.getLogger(    "scapy.runtime").setLevel(logging.ERROR)     
      #    屏蔽模块IPV6多余告警
          from scapy.all   import traceroute
      domains=raw_input(    "please input you   domain name:\n")

    #接受输入的域名或IP
      target=domains.split(    " ")
      dport = [    80]
     
          if len(target) >=1 and target[0]!='':
         res,unans =traceroute(target,dport=dport,retry=-    2)#启动路由跟踪
         res.graph(target=    "> test.svg")    #生成svg图片
         time.sleep(    1)
         subprocess.Popen(    "/usr/bin/convert test.svg test.png",shell=True)
          else:
             print("IP/domain name Error")
