I've installed all of the ganglia packages listed on the IBM site, as well as
the requisites, using YUM. I believe that gmond and gmetad are installed
correctly, I see data being collected, etc. Gstat gives me good info:
/opt/freeware/bin/gstat --all --single_line

But no graphs show up. Period. If I poke around a bit I get some php errors:
[08-Aug-2019 08:56:42 America/Los_Angeles] PHP Fatal error: Uncaught Error: []
operator not supported for strings in
/opt/freeware/apache2/htdocs/ganglia/cluster_view.php:34

I assume this is the cause of my problem, but since I can't find decent
documentation I am not really sure. HELP!! I've been banging my head against
the wall for days now...
