Automation tools improve management efficiency, though migration process is time-consuming and support could be more knowledgeable
The best features of ConnectWise RMM are the automation tools that they've included, which are quite good, enabling us to mass manage systems, schedule scripts, etc. We use some of the probe features in ConnectWise RMM that do network discovery and monitoring capabilities. ConnectWise RMM helps our team maintain network visibility and proactively address potential issues since the product works effectively at unknown device discovery, making it better than sending someone to the site for a manual discovery. ConnectWise RMM helps in automating security updates and maintaining endpoint security. We appreciate that their NOC team does evaluations on the security updates, allowing us to free up our time and making it a huge timesaver for us. The ability to do deployments through ConnectWise RMM's scripting features allows us to deploy new software or monitor the status of antivirus or system protection software, presenting another measurable benefit for us regarding ROI.

Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.
