Amir  Said - PeerSpot reviewer
Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.

Real-time analytics and alerts improve application performance and network operations
OmniPeek's ability to convert application visibility into flow helps me quickly understand application performance over LAN, WAN, or wireless. Its real-time analytics, integrated with LiveNX, allow me to monitor business-critical applications and set up alerts for application performance issues. This centralized dashboard and alert system is highly valuable for maintaining network operations.
