While trying to get the measures corresponding to the instance with metric id: 

~~~
[root@allinone10 ~(keystone_admin)]# gnocchi measures show 5345d4cd-2963-4975-830a-a450aae945d2 --resource-id a6508f68-d8bf-4833-995a-4fc864297875
Metric 5345d4cd-2963-4975-830a-a450aae945d2 does not exist (HTTP 404)
~~~

when using metric name, it's showing me all metrics which are registered in gnocchi which is not expected, as I am interested only in the value of particular instance.

How reproducible:
Everytime on test setup. 

Steps to Reproduce:
1. Spawn an instance, wait for gnocchi to register that instance. 
2. Try to fetch the measures for that instance by using metric id. It's throwing an error
3. Try to fetch the measure for that instance by using metric name, it's dumping all metrics which are registered for all instances. 

Actual results:
Not clear why metric id is not working.

Expected results:
It should give some meaningful error if nothing is present in gnocchi for particular metric id corresponding to instance resource. 

Additional info:

Comment 1 Mehdi ABAAKOUK 2017-04-10 15:24:10 UTC

You must not set the resource-id if you get the measures with the metric id, this is enough:

$ gnocchi measures show 5345d4cd-2963-4975-830a-a450aae945d2


When resource-id is set that means that the metric argument is a name and not an ID.

In your case metric ID "5345d4cd-2963-4975-830a-a450aae945d2" is the cpu.util of the instance a6508f68-d8bf-4833-995a-4fc864297875 

You need to choice between metric ID, or resource ID + metric name. Mixing them doesn't work.


Does that answer your question ?

Comment 2 VIKRANT 2017-04-10 16:16:13 UTC

Thank. Yes, it does answer my query.

I was mixing metric id + instance id which as per your comment is not a valid combination. 

Closing this bug.

Once again, thanks for your help.
