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.

Has helped detect server failures in real time and improved incident response through clear dashboards
When I use PRTG Network Monitor, it shows which servers go down or crash, displaying real-time reports and related information. We have configured PRTG Network Monitor to trigger an alert if any sensor or server goes down for more than five minutes. PRTG Network Monitor shows cause and effect clearly. For example, when our internet link failed, it displayed which dependent services were impacted. The feature in PRTG Network Monitor improved communication within my team since everyone can see the same dashboard. It saves me from constant manual checks as everything I care about is automatically tracked. PRTG Network Monitor has positively impacted my organization because it shows cause and effect clearly. We can see the real-time dashboard and take immediate action based on that. PRTG Network Monitor helped us detect the failing RAID controller before it completely collapsed, allowing us to avoid potential data loss.
