我正在尝试以某种方式监视 Web 服务器，即我想通过 http 在页面上搜索特定字符串。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，我已经测试过并且发现它运行良好。
每当我更改命令定义以搜索页面上没有的字符串并重新启动 nagios 时，我都会在 Web 界面上看到未找到该字符串。我不明白的是，为什么没有发送通知，尽管我已经定义了主机、主机组、联系人、联系人组和服务等等。我缺少的是，这些是我的定义，在我通过 cgi 进行 Web 访问时，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。
主机配置文件

主机组_nagios2.cfg

有人能告诉我哪里错了吗？
以下是通用主机和通用服务的定义

答案1
我搞明白了，实际上配置没问题，问题是 nagios 以用户“nagios”的身份执行 SMS 脚本，而该用户没有权限写入 /tmp/ 中的日志文件。但我读过的所有关于通过 SMS 设置 nagios 通知的博客都没有解释这一点。我不得不自己找出答案，差点让我头晕目眩。
