Paolo Sala - PeerSpot reviewer
A reasonably priced tool for system and application monitoring
The main room for improvement is in the solution's presentation and the integration area. In our company, we use the integration capabilities from ServiceNow. We also have another big monitoring solution in place in our company, which is Dynatrace. At the moment, there doesn't exist an out-of-the-box integration for Dynatrace. I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most. The only implementation of Checkmk that allows high availability is the virtual appliance that has the option for the availability of a different box. Otherwise, you have to find a way to implement it manually with some custom solution, which could be an improvement.

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.
