I think that adding group names as multiple entities in their own
right, rather than a CSV list, would make it much easier to find
metrics that are part of a given group.
<GANGLIA_XML>
<CLUSTER>
<HOST>
<METRIC name='queries_per_second'>
<GROUP>mysql</GROUP>
<GROUP>other-group</GROUP>
</METRIC>
</HOST>
</CLUSTER>
</GANGLIA_XML>
With something like that, it's easy to find all metrics which are in a
group with a simple XPath query.
$query = "/GANGLIA_XML/CLUSTER/HOST/METRIC[GROUP='mysql']"
With the csv list approach, you'd have to select all metrics and do
extra string processing on the 'GROUP' attribute to find the ones you
wanted.
Just my 2 cents,
