当使用icinga进行自定义插件时，需要修改commands.cfg和host.cfg文件。修改完文件，需要重启icinga，有时候会出错，如下：
[root@test libexec]# service icinga restart Running configuration check...CONFIG ERROR! Restart aborted. See /usr/local/icinga/var/icinga.chk for details.
这时需要查看问题到底出现在哪里，查看配置出错信息的方法如下：
[root@test icinga]# /usr/local/icinga/bin/icinga /usr/local/icinga/etc/icinga.cfg Icinga 1.11.5 Copyright (c) 2009-present Icinga Development Team (http://www.icinga.org) Copyright (c) 2009-2013 Nagios Core Development Team and Community Contributors Copyright (c) 2009-2013 icinga-cnä¸æåç» Copyright (c) 1999-2009 Ethan Galstad Last Modified: 06-20-2014 License: GPL Warning: Duplicate definition found for command 'check-snmp-perl-memory' (config file '/usr/local/icinga/etc/objects/commands.cfg', starting on line 295) Error: Could not add object property in file '/usr/local/icinga/etc/objects/commands.cfg' on line 296. Bailing out due to one or more errors encountered in the configuration files. Run Icinga from the command line with the -v option to verify your config before restarting. (PID=15091)
这里就可以明确看到出错的具体原因，根据原因查找问题所在，解决即可。
