gnocchi metric list fails with unauthorized error

[narasimha18sv]

I have installed gnocchi with master code. Getting below error. No other specific logs.
Environment is with ceilometer,gnocchi and panko installed.

openrc credentials I used.
export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=cloud123
export OS_AUTH_URL=http://192.168.56.101:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

Even after sourcing the openrc present in devstack folder also getting the same issue

Has anyone found a solution to this? I also get this when attempting to use the grafana plugin.

using curl:

```
$ AUTH_TOKEN=$(/usr/bin/openstack token issue -c id -f value)
$ /usr/bin/curl -s -X GET -H "X-Auth-Token: $AUTH_TOKEN" http://controller:8041/v1/metric
401 Unauthorized

I found this was a problem with the storage.ceph_keyring file. The docs say this has to be the path to the keyring file so I had only entered the directory. Once I added the directory and filename, the problem was resolved.
