Elasticsearch is developed in Java and is released as open source under the terms of the Apache License. Elasticsearch is the second most popular enterprise search engine. Shay Banon created Compass in 2004. Elasticsearch BV was founded in 2012 to provide commercial solutions around Elasticsearch and related software.
Nagios, an open-source computer-software application, monitors systems, networks and infrastructure. Nagios offers monitoring and alerting services for servers, switches, applications and services. It alerts users when things go wrong and alerts them a second time when the problem has been resolved. Ethan Galstad and a group of developers originally wrote Nagios as NetSaint. As of 2015 "Agios" also transliterates the Greek word, which means "saint".
