Certainly possible. If you find it hits the controller's performance, install it on a dedicated server.

Gnocchi uses two databases. The sample database, by default MongoDB I think (which is not SQL), and the database for Gnochi's operational data. For the latter it uses the SQL DB.

The databases don't interfere, except in a performance sense. You should also have full flexibility to put the databases anywhere (both SQL and Mongo). Some deployments have separate servers just for the SQL database, or you could have separate SQL databases for different services.

Thanks Bausch, I was worried about interfere between mariaDB SQL that is installed in Controller and the Gnnochi SQL database, so you think there is no problem. Yes?

@bernd-bausch - Gnocchi doesn't use MongoDB, available backends:

- file
- ceph
- swift
- s3
- redis

Thanks. Looks like my information is outdated. Ceilometer used to store samples in MongoDB; I wrongly assumed that Gnocchi did the same.

In any case, there should be none of the interference the OP was fearing.
