我想监视站点 A，如果请求来自站点 B，则仅接受对某个 URL 的请求。我知道Wget可以选择下载受引荐来源网址保护的内容，如下所示
wget --referer=http://first_page http://second_page
是否有任何Nagios插件可以实现这一点，或者check_http是否能够做到这一点？
我们让 Nagios 监控我们的 Web 服务器、邮件服务器和网络设备，我想知道是否有人会推荐一个好的插件或工具，它使用 Nagios 数据以一种像样的方式创建关于主机和服务的清晰性能报告。我想到的是图形、图表等。
我正在尝试以我想通过 http 在页面上搜索特定字符串的方式监视 Web 服务器。该命令在 command.cfg 中定义如下
# 'check_http-mysite command definition'
define command {
command_name check_http-mysite
command_line /usr/lib/nagios/plugins/check_http -H mysite.example.com -s "Some text" }
# 'notify-host-by-sms' command definition
define command {
command_name notify-host-by-sms
command_line /usr/bin/send_sms $CONTACTPAGER$ "Nagios - $NOTIFICATIONTYPE$ :Host$HOSTALIAS$ is $HOSTSTATE$ ($OUTPUT$)"
}
# 'notify-service-by-sms' command definition
define command {
command_name notify-service-by-sms
command_line /usr/bin/send_sms $CONTACTPAGER$ "Nagios - $NOTIFICATIONTYPE$: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ ($OUTPUT$)"
}
现在，如果 nagios 在主页 mysite.example.com 上找不到“某些文本”，nagios 应该通过 Clickatell http API 通过短信通知联系人，我有一个脚本，我已经测试过它并发现它工作正常.
每当我更改命令定义以搜索不在页面上的字符串并重新启动 nagios 时，我可以在 Web 界面上看到未找到该字符串。我不明白的是，虽然我已经定义了主机、主机组、联系人、联系人组和服务等，但为什么没有发送通知。我错过了什么，这些是我的定义，在我通过 cgi 进行的 Web 访问中，我可以看到我已经定义并启用了通知，尽管在硬状态更改期间我没有收到电子邮件和短信通知。

有人可以告诉我哪里出错了。
