Betreff: AW: [torqueusers] [near-offtopic] howto separate ganglia gmetad and 
web?

You can find all what you need in the config.php file. 

        # If you installed gmetad in a directory other than the default
        # make sure you change it here.
        #

        # The original Perl gmetad.
        #$gmetad_root = "/usr/local/gmetad";

        # The high-performance gmetad.
        $gmetad_root = "/var/lib/ganglia";
        $rrds = "$gmetad_root/rrds";

        # Leave this alone if rrdtool is installed in $gmetad_root,
        # otherwise, change it if it is installed elsewhere (like /usr/bin)
        define("RRDTOOL", "/usr/bin/rrdtool");

        #
        # If you want to grab data from a different ganglia source specify it   
#here.
        # Although, it would be strange to alter the IP since the Round-Robin
        # databases need to be local to be read. 
        #
        $ganglia_ip = "127.0.0.1";
        $ganglia_port = 8652;

        # Old-style names.
        $gmetad_ip = $ganglia_ip;
        $gmetad_port = $ganglia_port;
