+
+You can monitor Solr using solr-exporter that exposes Solr's metrics to
https://prometheus.io[Prometheus], and visualize metrics using https://grafana.com[Grafana].
+
+It allows users to monitor not only Solr metrics which come from
<<metrics-reporting.adoc#metrics-api,Metrics API>> but also facet counts which come from
<<searching.adoc#searching,Searching>>.
+
+.solr-exporter Diagram
+image::images/monitoring-solr-with-prometheus-and-grafana/solr-exporter-diagram.png[image,width=600]
+
+This feature is experimental status.
+
+== Running solr-exporter
+
+You can start solr-exporter by running `./bin/solr-exporter` from the
solr-exporter directory.
+
+[source,plain]
+----
+$ cd ./contrib/prometheus-exporter
+$ ./bin/solr-exporter -p 9983 -b http://localhost:8983/solr -f
./conf/config.yml -n 8
+----
+
+If you are on Windows platform, you can start solr-exporter by running `.\bin\solr-exporter.cmd`
instead.
+
+[source,plain]
+----
+> cd .\contrib\prometheus
+> .\bin\solr-exporter.cmd -p 9983 -b http://localhost:8983/solr -f
.\conf\config.yml -n 8
+----
+
+You can also connect to Solr in SolrCloud mode like this.
+
+[source,plain]
+----
+$ cd ./contrib/prometheus
+$ ./bin/solr-exporter -p 9983 -z localhost:2181/solr -f ./conf/config.yml -n 16
+----
+
+See command help:
+
+[source,plain]
+----
+$ ./bin/solr-exporter -h
+usage: SolrCollector [-h] [-v] [-p PORT] [-b BASE_URL] [-z ZK_HOST] [-f CONFIG]
+ [-n NUM_THREADS]
+
+Prometheus exporter for Apache Solr.
+
+optional arguments:
+ -h, --help show this help message and exit
+ -p PORT, --port PORT solr-exporter listen port
+ -b BASE_URL, --baseurl BASE_URL
+ specify Solr base URL when connecting to Solr in
standalone mode (for
+ example 'http://localhost:8983/solr')
+ -z ZK_HOST, --zkhost ZK_HOST
+ specify ZooKeeper connection string when
connecting to Solr in
+ SolrCloud mode (for example 'localhost:2181/solr')
+ -f CONFIG, --config-file CONFIG
+ specify configuration file
+ -n NUM_THREADS, --num-thread NUM_THREADS
+ specify number of threads
+----
+
+The Solr's metrics exposed by solr-exporter can see at the following URL.
+
+http://localhost:9983/metrics[http://localhost:9983/metrics]

+
+== Prometheus Settings
+
+You need to specify the solr-exporter listen address into `scrape_configs` in `prometheus.yml`.
See following example:
+
+[source,plain]
+----
+scrape_configs:
+ - job_name: 'solr'
+ static_configs:
+ - targets: ['localhost:9983']
+----
+
+When you apply the above settings to prometheus, it will start to pull Solr's metrics from
solr-exporter.
+
+
+== Grafana Dashboard
+
+A Grafana sample dashboard is provided at the following JSON file.
+
+`./conf/grafana-solr-dashboard.json`
