It isn't possible to create a spoofing metric module in the 3.1 code yet. This
is functionality that I just recently added to the trunk source tree but since
it touched so many files, I didn't want to take a chance of destabilizing the
3.1 branch. If you pull and build the trunk source tree, you should be able to
build a spoofing metric module by simply adding the SPOOF_HOST and SPOOF_NAME
to the metric description for a python module, or adding the same data as extra
data for a C module.
Python example:
d1 = {'name': 'my_spoof_metric',
'call_back': my_spoof_handler,
'time_max': 90,
'value_type': 'uint',
'units': '%',
'slope': 'both',
'format': '%u',
'description': 'Some spoofed metric',
'groups': 'spoof',
'spoof_host': 'spoof_ip_address:spoof_host_name', #Same format as the
gmetric -S option
'spoof_name': 'alternate_metric_name'} #Optionally
specify and alternate metric name
Hope this helps,
Brad
