Nagios vs Sumo Logic

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".

Sumo Logic is built around a globally distributed data retention architecture that keeps all log data available for instant analysis, eliminating the need for an enterprise to manage the cost and complexity of data archiving, backups and restoration.
