So if you copy these to your production server you conserve all historic data from the test box.
After the copy is complete you can start the MRTG process again." It is well explained in this post: https://lists.oetiker.ch/pipermail/mrtg/2007-October/033185Thank you for your help.
If you use this method, you will need to have your periodic update script restart / stop the daemon when the configuration changes.- Make sure you have all following packages install for successful installation of snmp plugin. net-snmp, net-snmp-devel, net-snmp-libs, net-snmp-utils, beecrypt-devel, elfutils-devel, elfutils-devel-static, lm_sensors - To install check_snmp I download the plugin from this location. Unzip the downloaded file bunzip check_snmp-1.1bz22. You also need to set up a cron job to regenerate the configuration periodically (see below).Note that our header template starts MRTG as a daemon (see below also).
