Andrzej Bialecki created SOLR-9960:
---------------------------------------
Summary: MetricsHandler should support multiple prefixes.
Key: SOLR-9960
URL: https://issues.apache.org/jira/browse/SOLR-9960
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Components: metrics
Affects Versions: master (7.0), 6.4
Reporter: Andrzej Bialecki
Assignee: Andrzej Bialecki
Priority: Minor
Fix For: master (7.0), 6.4
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".
