Debian Nagios常见错误解决方案
1.Sorry, but Nagios is currently not checking for external commands
You probably saw following message “Sorry, but Nagios is currently not checking for external commands, so your command will not be committed” when you tried to reschedule a service check in nagios web interface. The reason behind this is that nagios by default does not check for external commands. To resolve that problem we need to reconfigure nagios.
