最近在試著配置nagios，按照手冊上配置完成後，啟動過程中報錯如下：

Check your configuration file(s) to ensure that they contain valid
directives and data defintions. If you are upgrading from a previous
version of Nagios, you should be aware that some variables/definitions
may have been removed or modified in this version. Make sure to read
the HTML documentation regarding the config files, as well as the
'Whats New' section to find out what has changed.

請各高手給指點，謝謝！！
《解決方案》
Error: Contact group 'sagroup' specified in service 'Check Disk' for host 'nagios_client' is not defined anywhere!
你這個沒定義。要不你再哪個service里把這一段給註釋了，要不定義一下。
《解決方案》
/usr/local/nagios/etc/objects/contacts.cfg定義聯繫人、組
/usr/local/nagios/etc/objects/commands.cfg 查看命令
《解決方案》
研究了幾天，已經搞定，謝謝
