How to use Gnocchi API on Openstack rocky

Question

I'm trying to use gnocchi API for read metric data.

So I installed Openstack with devstack( I attached a configuration file (local.conf) ). I think I installed ceilometer and gnocchi for collected data. But when i try to read data on API server and CLI, it dones't work. Can you please explain why it doesn't work?

command 'openstack metric list' works well, but 'gnocchi metric list' doesn't work at all. with below message.

Unable to establish connection to http://localhost:8041/v1/metric?: HTTPConnectionPool(host='localhost', port=8041): Max retries exceeded with url: /v1/metric (Caused by NewConnectionError(': Failed to establish a new connection: [Errno 111] Connection refused',))

also when I post https://localhost/metric/v1/metric (which is API Access say metric URL) with X-Auth-Token as follow gnocchi api says, It doesn't work.

I am also experiencing the same issue, can someone please share a solution for this? — avimehenwal

It's couse gnocci cli are looking for endpoint like http://servername:8041. You should create new endpoints for gnocci service as in documentation https://docs.openstack.org/ceilometer/rocky/install/install-base-rdo.html Also you should ensure the redis or other backend service is enabled and active
