我在 ubuntu 12.04 上安装了全新的 nagios3。登录到 Web 界面并单击任何链接后，我收到错误消息：
Error: Could not read object configuration data!
Here are some things you should check in order to resolve this error:
Verify configuration options using the -v command-line option to check for errors.
Check the Nagios log file for messages relating to startup or status data errors.
我用 -v 选项运行它，它没有报告任何错误：
Total Warnings: 0
Total Errors: 0
Things look okay - No serious problems were detected during the pre-flight check
nagios 日志和 apache 错误日志和调试日志都与此无关。有谁知道如何打开日志，这会给我一些有用的错误？或者，如果有人知道如何在没有额外日志记录的情况下解决这个特定问题，我想这也可以。
谢谢！
