The :program:`ceilometer` shell utility
|
|
=========================================
|
|
|
|
.. program:: ceilometer
|
|
.. highlight:: bash
|
|
|
|
The :program:`ceilometer` shell utility interacts with OpenStack Ceilometer API
|
|
from the command line. It supports the entirety of the OpenStack Ceilometer API.
|
|
|
|
You'll need to provide :program:`ceilometer` with your OpenStack credentials.
|
|
You can do this with the :option:`--os-username`, :option:`--os-password`,
|
|
:option:`--os-tenant-id` and :option:`--os-auth-url` options, but it's easier to
|
|
just set them as environment variables:
|
|
|
|
.. envvar:: OS_USERNAME
|
|
|
|
Your OpenStack username.
|
|
|
|
.. envvar:: OS_PASSWORD
|
|
|
|
Your password.
|
|
|
|
.. envvar:: OS_TENANT_NAME
|
|
|
|
Project to work on.
|
|
|
|
.. envvar:: OS_AUTH_URL
|
|
|
|
The OpenStack auth server URL (keystone).
|
|
|
|
For example, in Bash you would use::
|
|
|
|
export OS_USERNAME=user
|
|
export OS_PASSWORD=pass
|
|
export OS_TENANT_NAME=myproject
|
|
export OS_AUTH_URL=http://auth.example.com:5000/v2.0
|
|
|
|
The command line tool will attempt to reauthenticate using your provided credentials
|
|
for every request. You can override this behavior by manually supplying an auth
|
|
token using :option:`--os-ceilometer-url` and :option:`--os-auth-token`. You can alternatively
|
|
set these environment variables::
|
|
|
|
export OS_CEILOMETER_URL=http://ceilometer.example.org:8777
|
|
export OS_AUTH_TOKEN=3bcc3d3a03f44e3d8377f9247b0ad155
|
|
|
|
From there, all shell commands take the form::
|
|
|
|
ceilometer <command> [arguments...]
|
|
|
|
Run :program:`ceilometer help` to get a full list of all possible commands,
|
|
and run :program:`ceilometer help <command>` to get detailed help for that
|
|
command.

V2 client tips
|
|
++++++++++++++
|
|
|
|
Use queries to narrow your search (more info at `Ceilometer V2 API reference`__)::
|
|
|
|
ceilometer sample-list --meter cpu_util --query 'resource_id=5a301761-f78b-46e2-8900-8b4f6fe6675a' --limit 10
