Nagios vs Riverbed

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".

Riverbed is known primarily for pioneering WAN Optimization with Riverbed SteelHead, which first shipped in 2004 and continues to lead the market with over 50% market share. As information technology has evolved over the past decade and begun to move to the cloud, Riverbed has also evolved: Businesses increasingly rely on applications and data that run both in on-premises data centers as well as in the cloud, delivered to users over a mix of private networks and public networks. This is the hybrid enterprise, and Riverbed offers a platform to give enterprises visibility to deliver, control, and optimize IT resources across this hybrid enterprise.
