Why Modern Network Monitoring Goes Beyond Up/Down Status
Let’s make no mistake, up front. The days of simply monitoring whether a device is online or offline are long gone. Modern network monitoring tools and software need to do so much more. They need to provide infrastructure metrics, traffic analytics, cloud telemetry, path visibility, synthetic testing, and AI-assisted investigation. NetOps teams must be agile from symptom to explanation these days. If an application is slow, you need to know right away if it’s a data center issue or a cloud provider problem or a problem with the ISP or a misconfigured firewall.
With the transition to cloud-based services and hybrid architectures, there is a growing demand for innovative monitoring capabilities. Nowadays organizations deploy workloads at on premise data centers, public cloud and edge locations. You need to have a single view of all of these environments in your monitoring solution. It also needs to adopt new concepts such as streaming telemetry for real-time visibility, AI correlation of events across the network and automated remediation workflows.
Keeping these points in mind, let’s take a look at the best options.

Open-Source vs. Commercial: Making the Right Choice
One of the most frequent choices that IT administrators face is that of open source vs commercial network monitoring solutions. Open-source options, such as Zabbix, Nagios and Cacti, do not require a license fee, and give you complete control over your monitoring setup. They are very powerful and flexible, but need technical skills to deploy, configure and maintain.
Commercial options such as SolarWinds, PRTG, and Datadog offer more enterprise-class stability, user-friendly interfaces, and quicker benefits realization. For larger deployments, however, costs of $20,000 per year can be exceeded.
Here is a new approach: It’s not always an either-or proposition. Many organizations take a “hybrid” approach. They leverage open source tools for basic infrastructure monitoring and add commercial tools in cases of specialty monitoring within the scope of a cloud observability or digital experience monitoring solution. The important thing to keep in mind is to match the selection to the ability of your team and your organization’s risk management profile.
