If I want to establish a customer billing system,do I need it ? It represents the fact we had no idea to use it when we write the code the first time. We discussed this yesterday, now we have a good plan. See https://bugs.launchpad.net/ceilometer/+bug/1070857 I do mean the cinder volumes , but I don't know how to configure it ,could you tell me more detailed steps on how to do this ? You need to configure the notifier to use rabbitmq (this is commented out in the default configuration file IIRC), to set the audit interval to something low like daily or hourlay (this should also be in the default configuration file) and to run this program into a cronjob. Same to cinder , detailed steps will be highly appreciated . Like cinder, you need to configure the notification backend to use rabbitmq. We have special instructions for configuring glance to use rabbit for notifications in http://ceilometer.readthedocs.org/en/latest/install.html#configuring-devstackbut I don't see anything about cinder there. Do we need to add another step to set the notification_driver for cinder? Doug If I modify the configuration file of service like nova or cinder , how to restart the related service in devstack ?

[Openstack] [OpenStack] Ceilometer API Glossary
Hi ,all I am testing ceilometer in my devstack virtual machine. Although I can see the meter data model in the mongodb, I am confused about some glossary when I test its Web API. I am not very clear about the resource in the GET /v1/resources,either source in the GET /v1/sources/(source)/meters/(meter). Can someone explain these two concept?

Hi Yawei, Good question! My understanding is that the resources collection refers to the set of UUIDs identifying the openstack entities (e.g. instance, volume, image ... etc.) being metered, whereas the source refers to the origin of the metering data and is effectively unused right now as there is only a single source currently (though we could in the future for example distinguish between metric and metering data in this way). That's exactly right. I'll open a ticket to add a glossary to the documentation.

Hi Yawei,
Good question!
My understanding is that the resources collection refers to the set
of UUIDs identifying the openstack entities (e.g. instance, volume,
image ... etc.) being metered, whereas the source refers to the
origin of the metering data and is effectively unused right now
as there is only a single source currently (though we could in the
future for example distinguish between metric and metering data
in this way).
Cheers,

Thanks Eoghan,
I still have questions about the data in the mongodb.
First: All the data about source in db is ?,for example:
-
source: ?,
metadata: {
fixed_ip_id: null,
host: null,
auto_assigned: false,
pool: nova,
address: 172.24.4.232
}
is it correct?
second,when I create a instance,there will be meter data created in the
mongodb as resource and meter,but for volume ,there is no any data
about volume in the db,so why ?Is there something wrong with my devstack
or there is configuration file should be modified?
third,I can only see cpu,disk,and network info for instance in the meter
data by now ,but there is no memory info,so why?
thanks
