Hi, Julien
I am using master branch and newest code for testing.
For the purpose for learning the structure of gnocchi, I changed the default
UUID type of mysql from binary to char, so I can easily link the resource-id(I
mean in database), metric id and directory name of storing measures.
When I did that, I found all the metrics where their resource id is
combined(here, I mean in Ceilometer, such as instance-xxx-tapxxxx) have no
measures stored.
Log in Ceilometer collector records this:
"
2015-09-11 07:55:55.097 10636 ERROR ceilometer.dispatcher.gnocchi [-] Resource
instance-00000001-4641f59e-994c-4255-b0ec-43a276d1c19c-tap8aadb7ad-d7 creation
failed with status: 400: <html>
<head>
<title>400 Bad Request</title>
</head>
<body>
<h1>400 Bad Request</h1>
The server could not comply with the request since it is either malformed or
otherwise incorrect.<br /><br />
Invalid input: required key not provided @ data['display_name']
</body>
</html>
"
So I wander whether gnocchi cannot deal with such combined resource-id metrics
or whether it is because I change the UUID type or whatever.
And another question is how to query measures for those metrics whose resource
id is combined.
For example, I want to query the network traffic of an vm, I know the instance
uuid 1111-2222, I know metric name 'network.incoming.byte.rate' but I do not
know the exact resouce_id and metric id. What procedure should I do ?

Which version are you testing? The master branch has no support for
resource ID that are not UUID.

We just merged support for those resources. We do not store any
attribute other than the name and parent instance AFAICS. What do you
miss as an attribute exactly?
