Hi,
I ran these all commands, however it did not work.
After running these commands I added a new device with SNMPv3 and the graphics still do not generate data in the bandwidth

Maybe it is a permission problem with some of the files as all of the tests seem to work running as root.
Lets change how the MRTG application runs.
Edit the /etc/cron.d/mrtg file and change this line from
Code: Select all
*/5 * * * * root LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lib/mrtg/mrtg.lock --confcache-file /var/lib/mrtg/mrtg.ok --user=nagios --group=nagios
to
Code: Select all
*/5 * * * * root LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lib/mrtg/mrtg.lock --confcache-file /var/lib/mrtg/mrtg.ok
Save the change and restart cron by running
service crond restart
Wait for 20 minutes and see if you start to see the bandwidth.

That is good news that it is working now. Let us know if it is OK to lock the post for you as solved.

I have been stalking this topic...now that the original user is happy, can I continue this thread?
Our environment also ran with improved reliability when running MRTG as an root, but it is still a bit ... unreliable. But either way, I don't really want to run MRTG as root - this server has secrets that need to be protected, and I consider the risks too high...
Do I need to start another thread?

Starting a new thread would be best to keep the issues separate.
