PerfCompositeMetric instance has attribute 'entity' and ChildEntity #27

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 

I could see an attribute check in method "get_entity_statistic" of 
vi_performance_manager.py

if composite:
            if hasattr(query, "Entity"):
                stats.extend(query.Entity.Value)
            if hasattr(query, "ChildEntity"):
                for item in query.ChildEntity:
                    stats.extend(item.Value)
        else:
            if hasattr(query[0], "Value"):
                stats = query[0].Value

When will happen this situation ???
AttributeError: PerfCompositeMetric instance has no attribute 'entity'
AttributeError: PerfCompositeMetric instance has no attribute 'ChildEntity'

Is this the only way to do it. 

Why can't we check value of attibutes (currentSupported or summarySupported) of 
PerfProviderSummary and proceed.
