Resource Quota Management
|
|
=========================
|
|
|
|
The amount of resources(e.g. alarms) that could be created by each OpenStack
|
|
project is controlled by quota. The default resource quota for each project is
|
|
set in Aodh config file as follows unless changed by the cloud administrator
|
|
via Quota API.
|
|
|
|
.. code-block:: ini
|
|
|
|
[api]
|
|
user_alarm_quota = -1
|
|
project_alarm_quota = -1
|
|
alarm_max_actions = -1
|
|
|
|
user_alarm_quota
|
|
The default alarm quota for an openstack user, default is unlimited.
|
|
Sometimes the alarm creation request satisfies the project quota but fails
|
|
the user quota.
|
|
|
|
project_alarm_quota
|
|
The default alarm quota for an openstack project, default is unlimited. The
|
|
cloud administrator can change project quota using Quota API, see examples
|
|
below.
|
|
|
|
alarm_max_actions
|
|
The maximum number of alarm actions could be created per alarm, default is
|
|
unlimited.
|
|
|
|
|
|
Quota API
|
|
---------
|
|
Aodh Quota API is aiming for multi-tenancy support. By default, only the admin
|
|
user is able to change the resource quota for projects as defined by the
|
|
default policy rule 'telemetry:update_quotas'. User alarm quota and alarm
|
|
action quota are not supported in Quota API.
|
|
|
|
An HTTP request example using ``httpie`` command:
|
|
|
|
.. code-block:: console
|
|
|
|
cat <<EOF | http post v2/quotas X-Auth-Token:$token
|
|
{
|
|
"project_id": "8aecc55977714e898281c24260747d78",
|
|
"quotas": [
|
|
{
|
|
"resource": "alarms",
|
|
"limit": 30
|
|
}
|
|
]
|
|
}
|
