A feature-packed solution with excellent stability and a notification system
LogicMonitor has good features, but the ease of use is a little bit confusing. Additionally, we are looking for workflow automation, which is a little bit tricky for LogicMonitor. But we are still exploring more and do not have detailed training in LogicMonitor. Moreover, the deployment process needs improvement. The thing is the deployment or whatever the standard deployment should be implemented here. That is not fine-tuning. In my personal opinion, for workflow automation and other stuff, we have Python or scripting knowledge, and that part is very tricky. Whenever we try to call the service or the LogicMonitor team, and we open a ticket, it is chargeable. In future releases, we would like to see a configuration backup manager. A feature that automatically backups the device configuration will help us. So, instead of going with another third-party tool, this will be good.

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.
