I know I should add a /dev/null somewhere, I tried
0-59/1 * * * * root /usr/bin/mrtg /etc/mrtg/mrtg.cfg > /dev/null
0-59/1 * * * * root /usr/bin/mrtg /etc/mrtg/mrtg.cfg 2 >&1 > /dev/null
Both does not work.
Just the other way around: > 0-59/1 * * * * root /usr/bin/mrtg /etc/mrtg/mrtg.cfg >/dev/null 2>&1
