Thank you for your feedback
If you have licensed the optional Extended Monitoring Plugin, or if you are using the Trial version of Composer, the Prometheus endpoint will expose extended metrics.
All extended metrics have the _ext_-prefix.
Extended monitoring plugin license
If you do not have the extended monitoring plugin license, all _ext_ metrics will be shown as 0 and do not update
Here is a list of all available metrics:
