no method is provided for storing sliver measurements

Description (last modified by chaos@bbn.com)

If i define a measurement and attach it to a sliver object, e.g.: 

  if timevals and len(timevals.keys()) > 0:
    foam_sliver_state = gmoc.SliverState()
    for rrd_time in sorted(timevals.keys()):
      foam_sliver_state.addData(rrd_time, timevals[rrd_time])
    sliver_obj.addMeasurement(foam_sliver_state)

there is no way to store that measurement data back to GMOC:

  • The store() method of GMOCClient iterates through all children of the POP object, storing their relations as well. The storeMeasurements() method does not iterate, but only stores the measurements for the given argument itself.
  • In addition, storeMeasurements() cannot be called on any class which doesn't define a POP. In particular, the code: 
    for [sliver_name, sliver_obj] in slivers.items():
  result = data.storeMeasurements(sliver_obj)
    yields: 
    Traceback (most recent call last):
  File "./report_relations", line 370, in <module>
    result = data.storeMeasurements(sliver_obj)
  File "/home/chaos/gmoc.py", line 2314, in storeMeasurements
    pop = obj.pop
AttributeError: 'Sliver' object has no attribute 'pop'

Description: modified (diff)

In my opinion, the correct fix is for storeMeasurements() to iterate down from a POP the same way store() does, for two reasons:

  1. It's inefficient to authenticate to GMOC once per sliver/resource/aggregate when submitting data.
  2. Monitoring client authors will find it surprising when they can call store() only once, but have to handle iterating on storeMeasurements() themselves. They are likely to make mistakes. The logic inside gmoc.py should be written to handle the relations and measurements cases the same way.

I think this is the most critical of the measurement bugs currently open.

Attempted to submit agg measurement data, but received: 16

I guess maybe i should close this ticket as resolved, but i think while the submission is failing, we can't tell.

One thing that jumps out at me is that slivers and datapath resources are defined as <node_name> in the data_group elements, but are not defined in <node_info>. I'm pretty sure the server won't accept that.

When i submit with the POP as the object, i seem to get the same result. So i think that much is working.
