Make sure the libapache2-mod-wsgi package has been uninstalled or upgraded to libapache2-mod-wsgi-py3. I believe that is the problem.

What version of OpenStack are you using?

2018-12-19 10:59:15 -0500 answered a question OpenStack Rocky - gnocchi-upgrade Failed

This error occurs because this file oslo_config/ does not get "opt" correctly from function _check_required_opts .

I have corrected this error using:

sudo chmod 777 /etc/gnocchi/*

I believe this error is because you forgot some tag in the multinode file. Run deploy with --debug to get more details about this problem.

Which version of OpenStack or DevStack are you installing? I have already installed several releases and they are all working.

2018-11-14 11:46:18 -0500 asked a question Enable metrics CPU Utilization in OpenStack Master (Stein)

In new release OpenStack Stein the transformation of data is no more the responsability of Ceilometer(cpu_util,, network.incoming.bytes.rate, ...)

According to the latest github commit of the Ceilometer, the gnocchi is responsible for these transformations. How do I configure them in gnocchi? I did not find any material explaining how to solve this problem.

2018-10-30 11:17:18 -0500 answered a question What OpenStack services are needed to use it as hypervisor

You can use the (OpenStack Ansible) or (OpenStack Kolla Ansible) project. These projects automate your installation of OpenStack services.

You will need the basic modules (Keystone, Glance, Neutron and Nova) for your setup.

I used the gnocchi-api with the shade. I believe it does not have python SDK for Ceilometer.

Are you using LinuxBridge or OVS in neutron module? The only documentation I know of that has separate installation of the network node is the installation with OVS. (

I recommend installing the Queens version. The master version (Rock) is still under development and can present many problems.

2018-06-06 15:52:36 -0500 asked a question Get meters SDN with Ceilometer and gnocchi Openstack Queens

Hello, I made a installation of the Openstack Queens Multi-node with (OVS). My setup has 3 nodes: one controller node, one network node and one compute node.

How do I configure ceilometer to get the metrics SDN controllers(switch.port.receive.bytes, switch.port.transmit.bytes)?

The (tutorial) only tells me that "These meters are available for OpenFlow based switches. In order to enable these meters, each driver needs to be properly configured."

Check the OpenStack client environment (scripts) . You must have entered some wrong field in this script.

This error occurred to me too. I had to reinstall the Openstack Multi node version Pike to fix this problem.

2018-04-27 14:19:51 -0500 asked a question Authentication gnocchi api is not working

I am developing an app which uses Gnocchi to collect some measures on OpenStack Pike. I intend to use the (gnocchi-api), but it is not clear how should I configure the environment to successfully authenticate. The code below is presented in the gnocchi-api docs and show how to authenticate using keystone.

from keystoneauth1 import loading
conf = cfg.ConfigOpts()
auth_plugin = loading.load_auth_from_conf_options(conf, "gnocchi_credentials")
gnocchi = client.Client(session_options={'auth': auth_plugin})

The problem come from the "conf" object: I have no info about what it is (a dictionary?), which data it carries and how to set proper auth info (username, password, project)... I appreciate any help on that!

2018-04-17 16:11:52 -0500 commented question gnocchi resource list has only type instance, instance_network_interface

What metric do you catch? Depending on the metric the configuration is different.

2018-04-17 14:47:52 -0500 commented question Openstack Pike Gnocchi Api Returns Empty List

The gnocchi is getting the meters correctly? The gnocchi-api who you describe works into the Openstack Client or in other machine?

Hi M.Pav, i remade the installation today. It worked (fine). I installed the same in my tutorial that I sent you. Sorry, I can not help with your installation errors.

2018-04-07 11:21:23 -0500 commented question How to use Grafana with Gnocchi?

Have you installed Devstack Pike or another version? Depending on the version installed, the graphfana data source settings are different.

2018-04-04 15:57:15 -0500 commented answer how to enable hardware metrics on gnocchi

I suggest you use the MIB Browser software and verify that it is necessary to use new MIBs and verify that the metrics are set up correctly. You perform a GET on your computer to verify that it has been configured correctly.

2018-04-04 15:25:56 -0500 commented question How to use Grafana with Gnocchi?

To access grafana you need to enter your IP with port 3000 (http: // your_IP: 3000). In my gitHub you have the steps for installing Devstack Pike (GitHub) and acessing grafana.
