Ganglia 3.0.x and earlier can only process single pieces of data, i.e. you
can¹t send it a mixed data type. So if you¹re monitoring packets on an
interface, you¹d have to capture each metric you¹re interested in (sent,
received, retransmitted, discarded, errors, etc.) individually and include
the data type in the gmetric command.
The options just indicate the kind of data you¹re trying to transmit, which
will affect how it¹s plotted and tabulated (i.e. you can average numbers but
not strings, decimal points are significant with floating point types, what
units you¹re measuring in, etc.)
The bottom line is, check what kind of data you want to collect, and help
Ganglia to understand it better. :-)
