I'm tinkering with a PHP class to access data on gmetad's interactive port,
making it easy to use this data in applications. Something along the lines of
what ganglia.php (from the current web frontend) does.
I'm trying to get a handle on the various ways gmetad may return XML. These
looks like the 2 typical data sets returned...
<!-- normal -->
<GANGLIA_XML>
<GRID>
<GRID>
<HOSTS/>
<METRICS></METRICS>
</GRID>
<CLUSTER>
<HOST>
<METRICS></METRICS>
</HOST>
</CLUSTER>
</GRID>
</GANGLIA_XML>
<!-- ?filter=summary -->
<GANGLIA_XML>
<GRID>
<HOSTS/>
<METRICS></METRICS>
<GRID>
<HOSTS/>
<METRICS></METRICS>
</GRID>
<CLUSTER>
<HOSTS/>
<METRICS></METRICS>
</CLUSTER>
</GRID>
</GANGLIA_XML>
>From a quick scan of the gmetad source, it looks like 'summary' is the only

I am I missing any other ways that gmetad might structure the XML it returns?
thanks,
alex
