This would suggest that you need to look at your MRTG config, not your Nagios one, and figure out why it hasn't updated in the last six hours.

Tony,
I hope you are part the XI technical team. I am new to nagiosxi and you need to give me steps to have this configure. I am not familiar with mrtg especially with xi server configuration. I do not find the paths and files the forums are pointing me to.

What created this configuration in the first place? Did you get it from one of the wizards (which one?), or build it yourself? I'm not really sure which of the stock things actually use that particular check frankly, so I'm a little surprised to be seeing it here.

I use the core config manager to create the configuration. I use the cli to copy the file I pasted.

What did you use to set up MRTG though? That's not in the CCM.

I do not configure mrtg. I understand that mrtg is pre install and pre configured in nagiosxi. I saw the plugins in /usr/local/nagios/libexec and try to add the service to a host.

MRTG isn't going to be configured to do anything on all of your hosts - it just exists to add configurations to. You'd be much better off just using the Switch Wizard to take care of all of the steps for you.
