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")
