Does this query returns anything?
curl -X GET -H 'X-Auth-Token:<token>' "http://localhost:8777/v2/meters
===================Just a comment:I notice that you have something wrong to. kvm requires that your CPU supports hardware-assisted virtualization (HVM) such as Intel VT-x or AMD-V. Because you are running openstack in a virtual machine, you should have used nova-compute-qemu package instead off nova-compute-kvm in order to install the compute services correctly. (This package provides software-based virtualization). Probably on your installation you have installed kvm package instead. (don't know if it help's on your current problem in ceilometer).
You probably should change libvirt_type=kvm to qemu on ceilolemeter.conf====================Cheers

Hey, Claudio!
That was a nice catch! But I don't know why I ceilometer continues to behave the same way. I have posted the query and the output for your reference here. I am indebted for your patience! :-)

Okay.
You don't have your rabbit configuration on your ceilometer.conf file.
rabbit_host=localhostrabbit_port=5672rabbit_userid=guestrabbit_password=guest
rabbit_retry_backoff=2rabbit_max_retries=0rabbit_use_ssl=False
See if this helps

It is a single node architecture, installed on Ubuntu 12.04 which is a Virtual Machine. I installed openstack using the manual instructions, not using devstack. I haven't installed quantum, since I don't need networking for the moment. And yes, I see that mongodb has a database ceilometer (size:203.125 MB) which has 5 collections: meter, project, resource, system.indexes and user, none of which have nova-specific data in them.

Have you have single node, devstack or multi-node openstack architecture ?

The logs presently don't have ERROR's or WARNING's, so I presume they are running well and as for the config file, I have customized it a bit. Please have a look at it here. Thank you so much for your patience! :)

Hi
Try to see if your daemons (api, collector, central agent, compute agent) are working without having issues. (see logs)!Have you configured your ceilometer.conf file or is the default one?
Are shore that you are filing your data base?

Hey, Brent!
Yes, I am using admin as the user for querying and keystone user-role-list has admin as one of its roles.

Jobin,
Please ensure that the token you are using was obtained with a user having the admin role.

Thanks Claudio for your detailed explanation, but the query returns me an empty list: [] Is something wrong with my nova-* or ceilometer-*?

Hi
Well, i am also trying to decode all the meters that ceilometer can return, and how to do most of the queries, but, to query some specific data, what I am doing is:Firs get the resource id number and then query using parameters in the curl command.
This is what I already tested:Get the resource id from what you want to query ceilometer
$ curl -X GET -H 'X-Auth-Token:<my_token_here' "http://localhost:8777/v2/resources | python -mjson.tool"
And then query with:
$curl -X GET -H 'X-Auth-Token:<my_token_here' "http://localhost:8777/v2/meters/cpu?q.field=resource_id&q.value=<resource_id_here> | python -mjson.tool"
Remember that option "q" is to filter rules for the resources to be returned, and try to use python mjson.tool, just for having something legible in your terminal.
Good luck :)

Hey, Claudio!
The command I executed is the second command in the page that you gave(which
is also the one I am referring to). Can you please pin-point what is
the mistake in the command or counsel what is the right one to get
nova-specific data? By the way, I replaced resource_id with the actual ID of the resource I wanted.

Hi Jobin
I think that your Curl command is not right. Look into this page for more info about meters from ceilometer.

Hey, all!
I installed ceilometer on Ubuntu 12.04 using the manual installation guide given here. However, I am having trouble getting data from it. When I do a ceilometer meter-list, all I get is a table with 4 rows with the names: image and image.size and its parameters; no CPU, vCPU and memory.
When I query using curl, I get some data regarding images installed and their sizes and ID and date of creation, etc.; no nova-specific data. This is how I query ceilometer using curl:
curl -X GET -H 'X-Auth-Token:<my_token_here' "http://localhost:8777/v2/resources/resource_id"
This returns a 404 Not Found error.
These are my primary concerns:
1) How do I query to get the CPU resources utilized by my virtual machines?
2) How do I decide on which port I have to pass this query? There are some documents which have v1 instead of v2 in the URL, I would like to have clarification on that too.
Thanks for your patience.
