Filtering Queries

|
=================
|
|
|
|
Many of the endpoints above accept a query filter argument, which
|
|
should be a list of Query data structures:

CLI Queries
|
|
+++++++++++
|
|
Ceilometer CLI Commands::
|
|
|
|
$ ceilometer --debug --os-username <username_here> --os-password <password_here> --os-auth-url http://localhost:5000/v2.0/ --os-tenant-name admin meter-list
|
|
|
|
or::
|
|
|
|
$ ceilometer --os-username admin --os-password password --os-tenant-name admin project-list
|
|
|
|
|
|
.. note:: The *username*, *password*, and *tenant-name* options are required to be present in these commands or specified via environment variables. Note that the in-line commands will override the environment variables.
|
|
|
|
|
|
API Queries
|
|
+++++++++++
|
|
Ceilometer API calls:
|
|
|
|
.. note:: To successfully query the Ceilometer you must first get a project-specific token from the Keystone service and add it to any API calls that you execute against that project. See the `Openstack credentials documentation <http://docs.openstack.org/api/quick-start/content/index.html#getting-credentials-a00665>`_ for additional details.

|
|
|
A simple query to return a list of available meters::
|
|
|
|
$ curl -X GET -H 'X-Auth-Token:<inserttokenhere>' "http://localhost:8777/v2/meters"
|
|
|
|
A query to return the list of resources::
|
|
|
|
$ curl -X GET -H 'X-Auth-Token:<inserttokenhere>' "http://localhost:8777/v2/resources"
|
|
|
|
A query to return the list of meters, limited to a specific meter type::
|
|
|
|
$ curl -X GET -H 'X-Auth-Token:<inserttokenhere>' "http://localhost:8777/v2/meters/disk.root.size"
|
|
|
|
A query using filters (see: `query filter section <http://docs.openstack.org/developer/ceilometer/webapi/v2.html#filtering-queries>`_)::
|
|
|
|
$ curl -X GET -H 'X-Auth-Token:<inserttokenhere>' "http://localhost:8777/v2/meters/instance?q.field=metadata.event_type&q.value=compute.instance.delete.start"
|
|
|
|
Additional examples::
|
|
|
|
$ curl -X GET -H 'X-Auth-Token:<inserttokenhere>' "http://localhost:8777/v2/meters/disk.root.size?q.field=resource_id&q.op=eq&q.value=<resource_id_here>"
|
|
|
|
or::
|
|
|
|
$ curl -X GET -H 'X-Auth-Token:<inserttokenhere>' "http://localhost:8777/v2/meters/instance?q.field=metadata.event_type&q.value=compute.instance.exists"
|
|
|
|
and finally, a JSON-based example::
|
|
|
|
$ curl -X GET -H 'X-Auth-Token:<inserttokenhere>' -H 'Content-Type:application/json' -d '{"q":[{"field": "timestamp","op": "ge","value":"2013-04-01T13:34:17"}]}' http://localhost:8777/v2/meters
