SOLR-10509, SOLR-10649: add docs for new metric features; add <metrics> to
solr.xml docs
> Document changes in SOLR-10418

> Key: SOLR-10509
> URL: https://issues.apache.org/jira/browse/SOLR-10509
> Project: Solr
> Issue Type: Task
> Security Level: Public(Default Security Level. Issues are Public)
> Components: documentation
> Affects Versions: master (7.0)
> Reporter: Andrzej Bialecki
> Assignee: Cassandra Targett

> SOLR-10418 added system properties to the metrics API, together with some
> other changes that should be documented:
> * {{solr.jvm}} metrics group now contains a compound metric (ie. a metric
> that has several mixed-type properties) named {{system.properties}}. This
> metric exposes most of key/value pairs from {{System.getProperties()}},
> except for some properties that are considered sensitive.
> * a new optional element {{/metrics/hiddenSysProps}} is now supported in
> {{solr.xml}} config file. It can be used for declaring what system properties
> are considered sensitive and should not be exposed via metrics API. If this
> element is absent a default list of hidden properties is used, equivalent to
> the following configuration:
> {code}
> <solr>
> ...
> <metrics>
> <hiddenSysProps>
> <str>javax.net.ssl.keyStorePassword</str>
> <str>javax.net.ssl.trustStorePassword</str>
> <str>basicauth</str>
> <str>zkDigestPassword</str>
> <str>zkDigestReadonlyPassword</str>
> </hiddenSysProps>
> ...
> </metrics>
> </solr>
> {code}
> * {{/admin/metrics}} handler now supports a {{property}} parameter that can
> be used for selecting a specific property from a compound metric. Multiple
> {{property}} parameters can be specified, which will act as a logical OR. For
> example, parameters
> {{prefix=system.properties&property=user.home&property=user.name}} would
> return just the two specified system properties. This property selection
> mechanism works also for other types of metrics that have multiple properties
> (eg. timers, meters, histograms, etc), for example
> {{property=p99&property=p99_ms}} will return only the 99-th percentile value
> from all selected histograms and timers.
