We briefly covered a wide variety of the issues that surround taking a Solr configuration that works in a development environment and getting it ready for the rigors of a production environment. Solr's modular nature and stripped down focus on search allows it to be compatible with a broad variety of deployment platforms. Solr offers a wealth of monitoring options, from log files to HTTP request logs to JMX options. Nonetheless, for a really robust solution, you must define what the key performance metrics are that concern you, and then implement automated solutions for tracking them.

Assuming you haven't already built your application, look back at Chapter 9, Integrating Solr, to see how easily you can integrate Solr search through various client libraries. Otherwise, just enjoy the stability and performance of the most popular search engine, helping your users find what they are looking for!
