The task has been completed.

Will the file automatically be created, or do I have to create the file?

The mrtg folders *should* be auto-created. You have to wait until 2 checks for each service have been received.

It seems that the graph charts are not generating at all, even though the mrtg directory was created yesterday and mrtg was installed since January.

I do not know if this is the problem, but I do not know if I have to manually configured each log file:
susetestbox:/usr/local/nagios/lib # more check_mrtg

******** check_mrtg: Not a text file ********


susetestbox:/usr/local/nagios/lib # more check_mrtgtraf

******** check_mrtgtraf: Not a text file ********

Also, MRTG is running as well:

susetestbox:/usr/local/nagios/etc/objects # ps flax | grep mrtg
0 0 32749 24585 20 0 2528 488 pipe_w S+ pts/0 0:00 \_ grep --color=auto mrtg

Run this command to update mrtg log file. Check crond to make sure you have a few entries that reseble:

susetestbox:/usr/local/nagios/etc/objects # env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg

If '2013-03-06' is not a typo you can use command-not-found to lookup the package that contains it, like this:
cnf 2013-03-06


susetestbox:~ # */5 * * * * /usr/bin/env LANG=C /usr/bin/mrtg /etc/httpd/conf/mrtg.cfg --logging /var/log/mrtg.log
-bash: */5: No such file or directory


susetestbox:~ # /5 * * * * /usr/bin/env LANG=C /usr/bin/mrtg /etc/mrtg/mymrtg.cfg .logging /var/log/mrtg.log
-bash: /5: No such file or directory

*/5 * * * * /usr/bin/env LANG=C /usr/bin/mrtg /etc/httpd/conf/mrtg.cfg --logging /var/log/mrtg.log

These are lines in a cron file, not commands. To possibly see if you have any of these entries, run:

Status:

susetestbox:~ # cat /etc/cron*/* | grep mrtg
susetestbox:~ #

It looks like you do not have any cron jobs setup for mrtg. How did you install core?
