> Some consumers of the {{/admin/metrics}} API need to retrieve only a number of specific metrics they are interested in, which don't share the same prefix. Additionally, selecting by "group" or "type" is insufficient when users need to retrieve metrics for a specific collection (all collections handled by a node belong to the same group "core").
> Concrete examples of this kind of use are in SOLR-9857 and SOLR-9858.
> The modification needed to support this in {{MetricsHandler}} is simple:
> * support multiple "prefix" parameters
> * support also "registryPrefix" parameter as an alternative to "group".
