Andrzej Bialecki commented on SOLR-10654:
------------------------------------------
Does Prometheus use a pull or push model for collecting metrics from monitored
systems? Metrics API uses {{SolrMetricReporter}} subclasses for pushing metrics
to external systems using custom formats, so that would be the way to go when
using push model.
Writer types are a kind of global thing, ie. should not be specific to a
particular handler.
