Cpanel 11.25 restructured the way that bandwidth RRD files are being processed, in that each service has two RRD files – one for peak, and one for rate. The “peak” file is used for long timespans of a month or longer, and the “rate” file covers a timespan of a week or less. The following is an example of files that would be created for domain.com:

domain
domain.com.5min
domain.com.hour
domain.com
domain.com.5min
domain.com.hour

Re rebuild the RRD databases for a user, run:

/usr/local/cpanel/bin/rebuildbwrrd <user>

To do this for the entire server:

/usr/local/cpanel/bin/rebuildbwrrd –all

Beware though that cPanel 11.25 requires a bit more disk space for the new bandwidth graphs, so if you have /var on a separate partition and there won’t be enough room, I recommend doing the following:

mv /var/cpanel/bandwidth /home

ln -s /home/bandwidth /var/cpanel/bandwidth

You’re basically moving the bandwidth graphs to another location and linking them to /var/cpanel/bandwidth.
