Zabbix using Pycurl module to monitor Web page status

Due to network problems, Zabbix with the Web module can not use, backstage research and Development 2b, always update the formal environment installation package, leading to problems, always give them wipe the buttocks, said this matter, they do not cooperate, now problems, very cool 650) this.width=650; "Src=" Http://img.baidu.com/hi/jx2/j_0025.gif "alt=" J_0025.gif "/>, this pot I said no back, I found pycurl this module to write a monitoring.

Pycurl Module Usage:

c = Pycurl. Curl () #创建一个curl对象

C.setopt (Pycurl. ConnectTimeout, 5) #连接的等待时间, set to 0 does not wait

C.setopt (Pycurl. TIMEOUT, 5) #请求超时时间

C.setopt (Pycurl. noprogress, 0) #是否屏蔽下载进度条, not 0 shielded

C.setopt (Pycurl. Maxredirs, 5) #指定HTTP重定向的最大数

C.setopt (Pycurl. Forbid_reuse, 1) #完成交互后强制断开连接, no reuse

C.setopt (Pycurl. fresh_connect,1) #强制获取新的连接, which is the substitution of connections in the cache

C.setopt (Pycurl. dns_cache_timeout,60) #设置保存DNS信息的时间, default is 120 seconds

C.setopt (Pycurl. URL, "http://www.baidu.com") #指定请求的URL

C.setopt (Pycurl. UserAgent, "mozilla/5.2 (compatible; MSIE 6.0; Windows NT 5.1; SV1;. NET CLR 1.1.4322;. NET CLR 2.0.50324) #配置请求HTTP头的User-agent

C.setopt (Pycurl. Headerfunction, GetHeader) #将返回的HTTP header directed to the callback function GetHeader

C.setopt (Pycurl. Writefunction, GetBody) #将返回的内容定向到回调函数getbody

C.setopt (Pycurl. Writeheader, Fileobj) #将返回的HTTP header directed to Fileobj file object

C.setopt (Pycurl. WriteData, Fileobj) #将返回的HTML内容定向到fileobj文件对象

C.getinfo (Pycurl. Http_code) #返回的HTTP状态码

C.getinfo (Pycurl. Total_time) #传输结束所消耗的总时间

C.getinfo (Pycurl. Namelookup_time) #DNS解析所消耗的时间

C.getinfo (Pycurl. Connect_time) #建立连接所消耗的时间

C.getinfo (Pycurl. Pretransfer_time) #从建立连接到准备传输所消耗的时间

C.getinfo (Pycurl. Starttransfer_time) #从建立连接到传输开始消耗的时间

C.getinfo (Pycurl. Redirect_time) #重定向所消耗的时间

C.getinfo (Pycurl. Size_upload) #上传数据包大小

C.getinfo (Pycurl. Size_download) #下载数据包大小

C.getinfo (Pycurl. Speed_download) #平均下载速度

C.getinfo (Pycurl. Speed_upload) #平均上传速度

C.getinfo (Pycurl. Header_size) #HTTP头部大小

Second, configure the Zabbix to customize the monitoring

This is relatively flexible, you can find a machine dedicated to monitoring, only need to configure the following on this machine to monitor multiple URLs.

A template can be configured in the Zabbix interface to hang it on the machine.

1. Write the code to the following directory and add the executable permission

[Email protected] scripts]# pwd/etc/zabbix/scripts[[email protected] scripts]# vim web_monitor.py [[email protected] scripts]# chmod +x web_monitor.py

2, Configuration zabbix_agentd.conf

[Email protected] scripts]# cat/etc/zabbix_agentd.confuserparameter=web[*],/etc/zabbix/scripts/web_monitor.py $ 2

3. Restart Zabbix-agentd

[Email protected] scripts]# service Zabbix-agentd restart

Third, configure Zabbix monitoring

Directly, the subsequent addition of the free play, a lot of return value can be out of the picture, can do trigger alarm and so on. Not much description of 650) this.width=650; "src=" Http://img.baidu.com/hi/jx2/j_0042.gif "alt=" J_0042.gif "/>
