当我在localhost中运行脚本时，它正在运行：

./check_last -p /root/Ratify/apache-tomcat-ratify/target/ratify.log -w 30 -c 40
**output:**
OK: /root/Ratify/apache-tomcat-ratify/target/ratify.log was last modified 24 seconds ago

当我从远程服务器运行脚本时，它无法正常工作：

./check_nrpe -H 00.00.0.00 -c check_ratify
NRPE: Unable to read output

请建议解决方案。

这通常是权限问题。如果nrpe或nagios用户无法访问您尝试stat的路径，那么您将获得该路径。我看到您的示例正在尝试访问/root目录下的文件，该目录只能由超级用户读取。

所以，我猜您是以root身份运行本地示例，但远程检查以nrpe或nagios运行。如果您确实需要访问该路径，则必须相应地配置权限。
