Export vert.x specific metrics when using Opentelemetry java agent.

[amit-dream11]

Vert.x has multiple monitoring integrations like Micrometer and Dropwizard.

When using Micrometer instrumentation, we get a decent amount of vertx specific metrics like pool, sql, http and all the quantiles. vertx_http_server_response_time_seconds, vertx_http_server_response_bytes, vertx_http_server_active_requests, vertx_pool_queue_pending, vertx_pool_ratio, vertx_http_server_requests_totaland many more.

On the other hand, when using opentelemetry-java-agent jar for auto instrumentation, there are only 3 kinds of metrics which are being exported right now; i.e http.server.request.duration_count, http.server.request.duration_bucket and http.server.request.duration_sum

Can we enable all the metrics (which are exported in Micrometer case) to be exported under opentelemetry-java-agent instrumentation as well ?

vert.x version used : 4.3.8

where is the opentelemtry java agent coming from ?

the vertx project does not maintain a metrics java agent (only tracing) and it seems the linked jar is coming from a third party project providing this implementation, it should be reported there
