[openstack-dev] Gnocchi

0 votes

Hello Mr/Mrs,

I am a student working on a project that involves an OpenStack Newton platform.

Currently, we are trying to implement the Data Collection service. We saw that Gnocchi is recommended for this purpose, and we installed it.

Now we have problems with the configuration.

I have tried to configure the basic parameters, but the same errors appear over and over.

Until this point, every installation and configuration of the services in OpenStack is done exactly the same as shown in the official OpenStack documentation.

I am sending you a screenshot of the output when I try to run gnocchi.

Can you help me with a basic configuration or some advice?

Thank you in advance.

Kind regards,

Simona Marinova

It looks like you set your Swift URL to a Keystone URL something like
that. Could you join your gnocchi.conf file?

Hello Julien,

Sorry for the late reply.

We uninstalled Gnocchi, because we tried to follow the latest update on OpenStack Newton which includes Ceilometer with MongoDB and Alarming with MySQL.

Ceilometer now works, but only the commands which do not include Alarming give the correct output, for example "ceilometer meter-list", "ceilometer resource-list" etc.

The Alarming service doesn't work at this point. For example the command "ceilometer alarm-list" gives the error:

HTTPConnectionPool(host='controller', port=8042): Max retries exceeded with url: /v2/alarms (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x7f1f51b90350>: Failed to establish a new connection: [Errno 111] Connection refused',))

Now our biggest concern is that the Alarming service database (MySQL-based) and the Telemetry service database (MongoDB) are not communicating properly. Is it possible for the Aodh to access the data from mongoDB?

Additionally aodh-dbsync gives error, because it cannot detect the module gnocchiclient. There aren't gnocchi modules involved in this version.

What kind of configuration needs to be done in order for Telemetry and Alarming to work properly?

Best regards,
Simona
