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.
Mohammed Hassan - PeerSpot reviewer
Helps us by providing root cause analysis when it comes to latency and performance issues
I would recommend NETSCOUT nGeniusONE to others yet not for small SMBs due to the pricing. It is important to have the necessary NETSCOUT experience for smooth integration. The automated issue detection sometimes has a few false positives but is overall cost-effective for our customers. I'd rate the solution eight out of ten.
