Widget Graph Monitoring - Add a filter on the metric

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.
