Antonin ...

I got it, but.... In the scenario of a integration that can be shared
between all tenants and avoid the deploy duplication of the same
integration by namespace.... I need to go by the strategy to have 1
integration scaled, if necessary, in 1 namespace.

In this case, all my tenants will share the same instance of the
integration, and the metrics and logs will be a mess.

Is it possible to customize the quartus micro profile metrics to
inject labels about the current tenant name? Or I need to create my
own metrics inside the route flux?
