Openstack disable Ceilometer


#1

Hey Support,

a short question about the Openstack Provider:

is the Ceilometer / AMQP connection mandatory, or is there an option to disable it ?
There is a cloud provider outside who will grant us no access to the Event-System…

Thanks


#2

Could someone take care of this question?

Thanks

Hi,
ManageIQ uses AMPQ to get events, Ceilometer for metrics and Events. If you configure Ceilometer to get events then you don’t need AMPQ.

If you are not receiving events, then you will don’t know when something changed in OpenStack and you will be out-of-sync.
If you don’t collect metrics, then you cannot have monitoring and chargeback.

Regards

i want to know if i just use AMPQ, i won’t get the metrics?

i thought can get metrics through AMPQ.

HI @yybear

How do you get metrics from AMQP ? For what provider ? Can you tell us more please. I want to run ceilometer for this purpose. But maybe there’s an opportunity not to do it?


#6

i can’t get metrics from AMQP.
i want to do this, because the guy responsible for openstack doesn’t want to start ceilometer server. so u know…

Yeah, if you have configured AMQP and enable “C & U Collection” in MIQ than Workers try to connect to ceilometer endpoint.

AMQP is only management events and ceilometers events have data for capacity usage.
