The gnocchi log files should contain details about the error.

Following config for /etc/apache2/sites-available/gnocchi.conf works fine at this moment:

Listen 8041

<virtualhost *:8041=""> WSGIDaemonProcess gnocchi lang='en_US.UTF-8' locale='en_US.UTF-8' user=stack display-name=%{GROUP} processes=2 threads=32 WSGIProcessGroup gnocchi WSGIScriptAlias / /usr/local/bin/gnocchi-api WSGIApplicationGroup %{GLOBAL}

        Allow from all

ErrorLog /var/log/apache2/gnocchi.log
CustomLog /var/log/apache2/gnocchi-access.log combined


WSGISocketPrefix /var/run/apache2

After service apache2 restart output for command gnocchi status is following:

$ gnocchi status +-----------------------------------------------------+-------+ | Field | Value | +-----------------------------------------------------+-------+ | storage/number of metric having measures to process | 0 | | storage/total number of measures to process | 0 | +-----------------------------------------------------+-------+

Not like before:

$ gnocchi status <html><head> <title>403 Forbidden</title> </head><body>


You don't have permission to access /v1/status on this server.

I faced the same 500 Internal Server Error, as posted above, for the same platform :Openstack Queens multi-node setup on Ubuntu 16.04.4 LTS. Gnocchi version: 4.2.4.

The Apache logs for gnocchi-api (/var/log/apache2/gnocchi_error.log) showed a Python import error:

root@OSControllerTest:/home/osctest# tail -f /var/log/apache2/gnocchi_error.log
2018-11-13 11:17:25.590909 Traceback (most recent call last):

2018-11-13 12:49:21.263823 ImportError: No module named gnocchi.cli

The import issue was resolved by installing the python-gnocchi package, as suggested by the author above:

apt install python-gnocchi

However, there was still an issue related to authentication (HTTP 401):

osctest@OSControllerTest:~$ gnocchi status
The request you have made requires authentication. (HTTP 401)

This was resolved by setting the environment variable OS_AUTH_TYPE=password in the admin-openrc file. The additional GNOCCHI_ENDPOINT variable as suggested by the author was not required, The final admin-openrc file looks like this:

export OS_USERNAME=admin
export OS_PASSWORD=test123
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_AUTH_URL=http://controller:5000/v3
export OS_AUTH_TYPE=password

After sourcing the updated openrc file, the gnocchi API seems to be working correctly:

osctest@OSControllerTest:~$ gnocchi status
| Field                                               | Value |
| storage/number of metric having measures to process | 0     |
| storage/total number of measures to process         | 0     |

osctest@OSControllerTest:~$ gnocchi server version
| Field   | Value |
| version | 4.2.4 |
