I have been testing with the latest of everything (every package).
I am running SLSE 11 SP2
When I export to CSV (or JSON), I am getting no data contents - only the
headers.
In diagnosing the issue, I found that the graph command result is returning
Some header fields that the xml parser does not like and when I stripped these,
the export worked.
The correction:
Graph.php line 879
From : $xml = simplexml_load_string($string);
To: $xml = simplexml_load_string(stristr($string, "<xport>"));
The command issued by graph.php
/usr/bin/rrdtool xport --start '-3600s' --end 'now'
