web监控:zabbix自动发现+python之pycur模块对网站访问质量监控
一、效果图:二、需求说明:
最近需要对节点到源站、办公环境访问业务平台网站质量和办公网络线路质量的监控,简单的ping可以检测到一些东西,但是http请求的检查也要进行,于是就研究了下pycurl。
PycURl是一个C语言写的libcurl的python绑定库。libcurl 是一个自由的,并且容易使用的用在客户端的 URL 传输库。它的功能很强大,PycURL 是一个非常快速(参考多并发操作)和丰富完整特性的,但是有点复杂的接口。三、python脚本:
1、编写httptime.py脚本命令vi zabbix_agentd.conf.d/httptime.py #!/usr/bin/python# coding: UTF-8import pycurlimport sysimport osimport json
class Test: def __init__(self): self.contents = '' def body_callback(self,buf): self.contents = self.contents + bufdef web_performance(input_url,mykey): t = Test() c = pycurl.Curl() c.setopt(pycurl.WRITEFUNCTION,t.body_callback) c.setopt(pycurl.ENCODING, 'gzip') c.setopt(pycurl.URL,input_url) c.perform() if mykey == "NAMELOOKUP_TIME": #DNS解析时间ms NAMELOOKUP_TIME =c.getinfo(c.NAMELOOKUP_TIME) print "%.2f"%(NAMELOOKUP_TIME1000) #return mykey elif mykey == "CONNECT_TIME": #建立连接时间ms CONNECT_TIME =c.getinfo(c.CONNECT_TIME) print "%.2f" %(CONNECT_TIME1000) #return mykey elif mykey == "PRETRANSFER_TIME": #准备传输时间ms PRETRANSFER_TIME = c.getinfo(c.PRETRANSFER_TIME) print "%.2f" %(PRETRANSFER_TIME*1000) #return mykey elif mykey == "STARTTRANSFER_TIME": #传输开始时间ms STARTTRANSFER_TIME = c.getinfo(c.STARTTRANSFER_TIME) print "%.2f" %(STARTTRANSFER_TIME1000) #return mykey elif mykey == "TOTAL_TIME": #传输结束总时间ms TOTAL_TIME = c.getinfo(c.TOTAL_TIME) print "%.2f" %(TOTAL_TIME1000) #return mykey elif mykey == "SIZE_DOWNLOAD": #下载数据包大小bytes/s SIZE_DOWNLOAD =c.getinfo(c.SIZE_DOWNLOAD) print "%d" %(SIZE_DOWNLOAD) #return mykey elif mykey == "HEADER_SIZE": #HTTP头部大小bytes HEADER_SIZE = c.getinfo(c.HEADER_SIZE) print "%d" %(HEADER_SIZE) #return mykey elif mykey == "SPEED_DOWNLOAD": #平均下载速度bytes/s SPEED_DOWNLOAD=c.getinfo(c.SPEED_DOWNLOAD) print "%d" %(SPEED_DOWNLOAD) #return mykey
def web_discovery():website = ['www.qq.com','www.sina.com','sunday208.blog.51cto.com'];devices = []for devpath inwebsite: device = os.path.basename(devpath) devices += [{'{#SITENAME}':device}]print json.dumps({'data':devices},sort_keys=True,indent=7,separators=(',',':'))
if __name__ == '__main__':if sys.argv == "web_discovery": web_discovery()if sys.argv == "web_performance": input_url = sys.argv mykey = sys.argv web_performance(input_url,mykey)
2、加上执行权限:命令chmod +x zabbix_agentd.conf.d/httptime.py
3、应用到zabbix客户端配置:命令tail -1 zabbix_agentd.confUserParameter=HTTP_CURL
[*],python /opt/soft/zabbix/etc/zabbix_agentd.conf.d/httptime.py $1 $2 $3
4、重启zabbix客户端:/etc/init.d/zabbix_agentdrestart
5、服务端测试:命令如下:
zabbix_get -s192.168.2.32 -p 10050 -k "HTTP_CURL"zabbix_get -s192.168.2.32 -p 10050 -k "HTTP_CURL"
四、WEB界面配置:1、下载附件模板文件(web访问质量监控.xml)后,导入到zabbix里。
2、模板中相关配置项展示:
3、创建主机并链接模板4、数据展示
懒人使用懒方法。第一次编写python,如果有问题,请大家及时更正。
