Doc Text:	Previously, the Metric drop-down list in the Stats tab of the Horizon admin/Resource Usage panel only listed type-specific meters of the first instance reported by the nova-api service. As a result, when instances of with different flavors are launched, Horizon only displayed type-specific meters from only one of those instances. With this release, Horizon now retrieves all type-specific meters from the Metering API service before rendering the Metric drop-down list. This ensures that all concrete 'instance.<type>' meters that exist in the Metering store are visible via the Horizon dashboard.	Story Points:	---

Description Eoghan Glynn 2013-11-21 13:17:23 UTC

Description of problem:

The Compute (Nova) meters list is generally incomplete in the Metric dropdown on the Stats tab of the admin/Resource Usage panel.

The content of this dropdown list also changes from time to time.

This is because the list is populated from the meter links in the *first* resource reported by the ceilometer API with availability zone metadata (i.e. indicating a nova instance).

However, the set of meters associated with instances is not uniform in ceilometer (i.e. a certain meter gathered for one resource may not necessarily be gathered for another).

Also the content of this list changes from time to time, depending on the order of sample acquisition (as a different instance, with a different set of associated meters, may be at the head of the resources list reported by the ceilometer API).

For example, once instances of different flavors have been spun up in an openstack deployment, the Metric list will not contain all the possible compute meters, nor will it even always be incorrect in the same way. Only the 'instance:<flavor>' meter relating to the first instance appears in the dropdown, and the identity of this first instance may change over time.

So at any given point in time, only a subset of the compute meters are accessible via the dashboard.

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

RHOS 4.0 beta

How reproducible:

100%

Steps to Reproduce:
1. Spin two instances with different flavor (say m1.tiny and m1.micro)

2. Open the admin/Resource Usage panel

3. Note that only one 'instance:<flavor>' meter is reported in the Metric downdrop box

Actual results:

Only one 'instance:<flavor>' meter is reported in the Metric downdrop box.

Expected results:

A 'instance:<flavor>' meter for each existing instance type should be reported in the Metric downdrop box.

launched 4 instance, 2 small and 2 medium.

Result:
it took a couple of minutes to update, but all instances types were listed in the dropdown list.
