Re: rrdtool update does not update one of my ds

It looks like you've added a new datasource since the graphs have been created.
At least, the update only defines a single data sources, svctm. The second,
avgqu_sz, is missing. Easiest way to solve this, is to rebuild_poller_cache.php
(see cli directory), at least for the given host (please make sure to run latest
cacti; the script has had a nasty bug!).
