openfalcon 添加http远程监控 (for status code and for content match)

• 做个falcon的小脚本,一来可以监控http的返回吗,如果是2xx或者3xx就是对的,否则就是111; 二来监控内容是否包含, 如果包含那就是对的,否则返回111

• 直接上代码

• 上配置文件

• 加cron

* * * * * cd /data/openfalcon/agent/userdefine && ./remotehttpcheck 1>>/tmp/1.txt 2>&1

• 看是否可以找到上报数据

• 添加报警template

咱们直接在上一个tcpcheck的 template模板里面进行添加

• 等待报警中…

• 搞定, 修改报警值
