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.
There are a few metrics that do not require the extended monitoring license, read more.
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:
