Vote for Orion Network Performance Monitor
Orion NPM enables you to quickly detect, diagnose, and resolve network performance problems and outages. Out-of-the-box, it offers network-centric views that are designed to deliver the critical information network engineers need. And Orion NPM is the easiest product of its kind to use and maintain, meaning you will spend more time actually managing networks, not supporting Orion NPM.
Orion NPM provides comprehensive performance, fault management and network availability tools to ensure that your network is always running at peak performance. Via a cutting-edge web interface, Orion NPM gives you a unified view into the performance of thousands of nodes and interfaces on your network. From a single web page, you can monitor performance metrics from any SNMP-enabled device, including routers, switches, firewalls and servers. Commonly monitored metrics include bandwidth utilization, packet loss, latency, errors, discards and quality of service.
