Ceilometer Http 500 - openstack

Question

I was installing Ceilometer using this guide: http://docs.openstack.org/developer/ceilometer/install/manual.html
After I have finished everything, I try to test it by using: ceilometer meter-list and it gives me this error: HTTPInternalServerError (HTTP 500)
Here's what I have in the log:
root#iaas-hk01:/etc/apache2/sites-enabled# tail -f /var/log/apache2/ceilometer_error.log

Hopefully someone can provide me some guidance in fixing this.

Answer 1

you should set the keystone api - end points. so that ceilometer api can talk with keystone...
Here are steps...
Create a service for ceilometer in keystone
$ keystone service-create --name=ceilometer \
--type=metering \
--description="Ceilometer Service"
Create an endpoint in keystone for ceilometer
$ keystone endpoint-create --region RegionOne \
--service_id $CEILOMETER_SERVICE \
--publicurl "http://$SERVICE_HOST:8777/" \
--adminurl "http://$SERVICE_HOST:8777/" \
--internalurl "http://$SERVICE_HOST:8777/"
Note that: 8777 is the default port of ceilometer if you have customised use the customised one..
