not relevant for your problem but units here should be "KB"

the rrd are generated by gmetad, which in turns reads them from your gmond.
for that to work on your setup you need to configure (/etc/gmond.conf) the
gmond in your head node with the same cluster name (shiva) and collector
than your work nodes, and then confirm that your gmetad is configured
(/etc/gmetad.conf) to pull the status for your cluster (shiva) including your
new metric.
telnet to port 8649 in your collector (any gmond if using multicast, or the
one that your gmetad is pointing to if using unicast) should dump an XML
description of your cluster and include the new metric you just created with
gmetric inside a host definition from your head node.

v, st, z, r are better pulled from the environment as you will be
otherwise hardcoding some of the values for your graph.
since you are trying to import a metric graph in a cluster view, that might
not work correctly anyway and so changes to graph.php might be needed too.
