1. The solr exporter can be found in a solr-7.3.1 binary distribution at ${BASE_DIR}/solr-7.3.1/contrib/prometheus-exporter. Or, if you're in the mood to type, in a riak build tree after make rel in ${BUILD_DIR}/riak/_build/rel/lib/yokozuna/build/solr-7.3.1/contrib/prometheus-exporter.

2. Besides the prometheus-exporter directory the exporter also requires the dist directory in the top-level solr-7.3.1 directory. That directory's jars are referenced in solr-exporter via ../../dist. In order to avoid placing additional full solr distributions¹ on the riak machines the dist directory is moved from solr-7.3.1/dist to ${EXPORTER}/dist and the solr-exporter script is edited to point to the new location.

3. Configuration information can be found on the solr website.
