> Routers.cgi*Ignore: yes
> Include: /etc/mrtg/device1.cfg
> Include: /etc/mrtg/device2.cfg

> You should tune the Forks: statement to your system; higher values run quicker but use more CPU and memory, lower values may not finish within the 5-min window. The Ignore line prevents routers2 from processing the file.

Thank you for the tip...
Just tried but the rrd files remain (all) untouched....
until now the only way is the crontab....
