# /usr/local/nagios/libexec/check_api -u 'http://xxx.com/ch1.ashx?jsoncallback=jQuery111104933076921983046_1479864376576&classid=12&systemtype=2&dataType=json&cityid=129&videoid=36065812&pageid=1&_=1479864376577' -S AdList
GET API OK：get AdList successfully!

一、上述插件在客户机上部署，将此插件放入/usr/local/nagios/libexec/ 赋予可执行权限和属主组，修改/usr/local/nagios/etc/nrpe.cfg配置文件，添加
|

|
command
[check_api]=
/usr/local/nagios/libexec/check_api
-u
'http://xxx.com/ch1.ashx?jsoncallback=jQuery111104933076921983046_1479864376576&classid=12&systemtype=2&dataType=json&cityid=129&videoid=36065812&pageid=1&_=1479864376577'
-S AdList

重启nagios客户端。
二、修改监控主机/usr/local/nagios/etc/objects/commands.cfg文件，添加

define
command
{
command_name check_api
command_line $USER1$
/check_api
-u $ARG1$ -S $ARG2$
