Can you please be more specific about what you are trying to solve? Is it in order to exclude certain metrics, or on the contrary to only select a few metrics? 

Note that some services might have a lot of metrics to filter from...

The specific need is to display only one or two metrics from a service containing more metrics.

To answer your question, I would like to choose a few metrics.

It’s possible with Centreon Map:
 

I know taht a service might have thousands of metrics, so maybe the solution is to type the name of the metrics or to use a regular expression.

Centreon Dashboards (beta) has been released in 23.10 and will deliver that idea. You can get more in the documentation and join the Beta Group.
