Hello, I installed OpenStack Newton on Ubuntu 16.04.2 with 3 nodes : controller, compute, block storage.

I recently installed ceilometer, when I want to see the resource usage in dashboard, an error message appears ( see the picture below ) :

And I noticed that I have some errors in the logs.

/var/log/ceilometer/ceilometer-agent-central.log ( controller node ) :
