Thank you for the response Vladimir. I have changed the location of the
rrds database. I had created a new filesystem for it. The rrds directory
is owned by nobody.nobody including the directories and files below it.
Please see below my changes to the configuration files. Have I missed
something else? Do I need to change the RRDS directory to be owned by
root including the directories and files below it? Thank you.

Subject: Re: [Ganglia-general] Timezone & Metrics Issue
"No matched metrics" is a catch all in case the web UI is not able to read
RRDs, RRDs are not there. It appears that /var/lib/ganglia/rrds is owned
by root. gmetad usually runs as nobody. Please make sure gmetad can write
into it.
