=== Logging and Metrics
* Metrics handler only depends on SolrJ instead of core and has its own
`log4j2.xml` and no longer shares Solr’s logging config.
-* Only `SearchHandler` and subclasses have "local" metrics now. It's now
tracked with a new `internal=true` tag, which can be filtered in e.g.
Prometheus.
+* Only `SearchHandler` and subclasses have "local" metrics now. It's now
tracked as if it's another handler with a "[shard]" suffix, e.g.
"/select[shard]".
There are no longer ".distrib." named metrics; all metrics are assumed to be
such except "[shard]". The default Prometheus exporter config splits that
component to a new label named "internal". The sample Grafana dashboard now
filters to include or exclude this.
* The default port of "Prometheus exporter" has changed from 9983 to 8989, so
you may need to adjust your configuration after upgrade.
* Logging is now asynchronous by default. There's a small window where log
messages may be lost in the event of some hard crash.
