The number of tools for IT Ops professionals to choose from is overwhelming. For this reason, we created the periodic table for IT Ops tools to better define, organize, and explain the IT Ops tooling landscape. It is our hope that it will help IT professionals find, explore, and choose tools for their future IT Ops stack.

In a portion of this table we dive into Network Monitoring tools specifically. Below you will find a list of the top network monitoring tools per the interactions we measure on the table.

What is NPMD?

According to Gartner, Network Performance Monitoring and Diagnostics (NPMD) solutions are critical to network visibility, performance issue detection, and root cause analysis. Gartner believes that these tools should allow IT professionals to fully understand the performance of application, network, and infrastructure components of a network. NPMD tools should monitor network traffic and infrastructure, while also providing solutions to outages and degradation. They should also help identify optimization opportunities through diagnostics, analytics, and root cause analysis.
