HTTP服務目前最流行的互聯網應用之一，如何監控服務的健康狀態對系統運維來說至關重要。
Zabbix本身提供了對WEB應用程序的監控，比如監控WEB程序的Download Speed,Response Time和Response Code等性能指標，但是配置起來比較繁瑣和複雜。下面通過 python pycurl模塊來獲取HTTP響應時間，下載速度，狀態嗎等性能指標。然後通過zabbix trapper的方式來監控WEB應用的性能。
Zabbix trapper監控是客戶端收集監控數據，然後以zabbix_sender的方式發送給zabbix server或者proxy服務器。發送的數據主要包括zabbix server或者proxy主機名，監控項和值。zabbix_sender具體用法如下：
[root@monitor]# /usr/local/zabbix/bin/zabbix_sender -help
Zabbix Sender v2.2.3 (revision 44105) (7 April 2014)
usage: zabbix_sender [-Vhv] {[-zpsI] -ko | [-zpI] -T -i <file> -r} [-c <file>]
Options:
-c --config <file> Absolute path to the configuration file
-z --zabbix-server <server> Hostname or IP address of Zabbix server
-p --port <server port> Specify port number of server trapper running on the server. Default is 10051
-s --host <hostname> Specify host name. Host IP address and DNS name will not work
-I --source-address <IP address> Specify source IP address
-k --key <key> Specify item key
-o --value <key value> Specify value
-i --input-file <input file> Load values from input file. Specify - for standard input
Each line of file contains whitespace delimited: <hostname> <key> <value>
Specify - in <hostname> to use hostname from configuration file or --host argument
-T --with-timestamps Each line of file contains whitespace delimited: <hostname> <key> <timestamp> <value>
This can be used with --input-file option
Timestamp should be specified in Unix timestamp format
-r --real-time Send metrics one by one as soon as they are received
This can be used when reading from standard input
-v --verbose Verbose mode, -vv for more details
Other options:
-h --help Give this help
-V --version Display version number
