The issue is that, notification is send after project is deleted, so no additional information can be fetched (i.e. project name,...). The GET request fails. As there is only project ID is in resource_info in the notification. In my case I at least need the name of the project. Thanks, Nader.

Re: [openstack-dev] [keystone] Notification When Creating/Deleting a Tenant in openstack
Hi Lance, And I'm doing the same. With the resource ID from the notification, I'm using the keystoneclient to get the project name. Regards, Nader.

The idea behind this when we originally implemented notifications in Keystone was to provide the resource being changed, such as 'user', 'project', 'trust' and the uuid of that resource. From there your plugin and could request more information from Keystone by doing a GET on that resource.

Re: [openstack-dev] [keystone] Notification When Creating/Deleting a Tenant in openstack
Hi Swann, I was able to listen to keystone notification by setting notifications in the keystone.conf file. I only needed the notification (CURD) for project and handle it in my plugin code so don't need ceilometer to handle them. The other issue is that the notification is only for limited to resource_id and don't have other information such as project name. Thanks, Nader.

Re: [openstack-dev] [keystone] Notification When Creating/Deleting a Tenant in openstack
Hi Nader, These notifications must be handled by Ceilometer like others [1]. it is surprising that it does not already identity meters indeed... probably nobody needs them before you. I guess it remains to open a BP and code them like I recently did for Heat [2] http://docs.openstack.org/developer/ceilometer/measurements.html https://blueprints.launchpad.net/ceilometer/+spec/handle-heat-notifications 2014-02-20 19:10 GMT+01:00 Nader Lahouti : > Thanks Dolph for link.

Hi All, I have a question regarding creating/deleting a tenant in openstack (using horizon or CLI). Is there any notification mechanism in place so that an application get informed of such an event? If not, can it be done using plugin to send create/delete notification to an application? Appreciate your suggestion and help.
