Hello,

I have installed mrtg on Nagios Core, but i get the message: MRTG data has expired (x minutes old). What can be done for this?
I also can not fix Nagios::Config... ***FAIL*** in the following.

The MRTG data has expired message could be caused by the crontab entry is missing or not running.
Take a look at this link for installing MRTG on your system and verify that cron is setup and running for MRTG.
