Description of problem:
-----------------------
It looks like CFME is only collecting CPU usage for Azure instances.Memory,disk and network metrics are not being collected for Azure instances.

#psql -d vmdb_production
1)vmdb_production=# select * from metrics where resource_name = 'TestRmVMOne' and derived_memory_used != 0\x\g\x
Expanded display is on.
(No rows)
2)vmdb_production=# select * from metrics where resource_name = 'TestRmVMOne' and disk_usage_rate_average != 0\x\g\x
Expanded display is on.
(No rows)
3)
vmdb_production=# select cpu_usage_rate_average  from metrics where resource_name = 'TestRmVMOne' and cpu_usage_rate_average != 0\x\g\x
Expanded display is on.
-[ RECORD 1 ]----------+---------
cpu_usage_rate_average | 0.250271
-[ RECORD 2 ]----------+---------
cpu_usage_rate_average | 0.250271


Version-Release number of selected component (if applicable):
------------------------
5.6.1.2


How reproducible:
-----------------
Always


Steps to Reproduce:
-------------------
1.Manage Azure.Enable C&U collection for Azure.
2.Check the DB for metrics collection.


Actual results:
---------------
Memory, disk, network metrics not being collected from Azure instances.


Expected results:
-----------------
Memory, disk, network metrics should be collected from Azure instances.


Additional info:
----------------
Not sure if Azure makes a distinction between Linux and Windows instances.
I've tested Windows instances.On the Azure Portal, I can see graphs for
these metrics for Windows instances:  CPU, memory, disk read, disk write disk read and write.No graphs for network usage were displayed on the Azure Portal.
