Isabelle Giguere commented on SOLR-17436:
-----------------------------------------
M'well ... Shows how little I knew about metrics before getting into this.
The V1 API supports 2 'wt' : `prometheus` and `openmetrics`
Both return a plain text response:
{noformat}
# TYPE solr_core_requests counter
# HELP solr_core_requests HTTP Solr requests
solr_core_requests_total{category="QUERY",collection="test",core="test_shard1_replica_n1",handler="/select",internal="false",otel_scope_name="org.apache.solr",replica_type="NRT",shard="shard1"}
1.0
solr_core_requests_total{category="ADMIN",collection="test",core="test_shard1_replica_n1",handler="/config",otel_scope_name="org.apache.solr",replica_type="NRT",shard="shard1"}
2.0 {noformat}
The new V2 JAX-RS APIs expect to return some extension of SolrJerseyResponse.
There's a code generator (Mustache) in SolrJ, that creates new classes based on
the solr-api interface and the request handler class. I have no idea how this
works, or why. Bottom line: if I create interface MetricsAPI with a method to
return a generic jakarta.ws.rs.core.Response, containing either Json or Text,
then, the "Mustache" fails to generate a compilable class... and boom!
If the method in the new interface MetricsAPI returns a SolrJerseyResponse,
then, the response only contains metadata (the names of the Prometheus fields).
I need to see if I can insert a "blob" somewhere...
