This file gets placed there by openvps-mon process, which you should have 
running (it's started by /usr/local/sbin/ovcheckproc which in turn is 
started from /etc/cron.d/openvps).

Basically there are two .rrd files for evey vserver right now, the one in 
/var/db/oh is obsolete - we're keeping it around so that there is 90 days 
of cross-over so that the rrd graphs look OK when /var/db/oh is killed.

There should be a ton more parameters in 
/usr/lib/python2.3/site-packages/openvps/host/dft.py, openvps.conf only 
contains most tweakable ones.

VAR_DB_OH is old, VAR_DB_OPENVPS is new. The rrd files in OPENVPS have a 
lot more variables. VAR_DB_OH is updated by /usr/bin/ohbwidth (run from 
cron), while the files in VAR_DB_OPENVPS are updated by the openvps-mon 
daemon. Eventually, VAR_DB_OH and /usr/bin/ohbwidth are going to get 
killed.
