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.
Masud Alam - PeerSpot reviewer
Offers alerting service to trigger alerts and easy to manage
For end-user performance monitoring, we like features such as availability of our all devices and device/interface monitoring. We have also used NCM (Network Configuration Manager) for our network. We use the alerting service to trigger alerts based on specific thresholds, like CPU or memory utilization exceeding a certain percentage. There are AI network initiatives in SolarWinds NPM for some lengthy issues. For example, it shows availability reports. But for bandwidth monitoring, it's not very clear how much bandwidth is being consumed. SolarWinds provide real-time bandwidth monitoring. It is not difficult to manage the network with SolarWinds. We have one customer with a satellite location. If we have a large network with, let's say, 43,000 elements, and our current SolarWinds license supports only 30,000, we would need to create another polling engine to accommodate the additional 13,000 elements. It's limited to the polling engine, so we can only support 30,000 elements per engine. So it's only for 30,000, but we have at least 40,000 elements in our network.
