The 4 Major Players in Network Performance Monitoring and Diagnostics

The 4 Major Players in Network Performance Monitoring and Diagnostics

These providers have recently been named major players in Network Performance Monitoring and Diagnostics by analyst house Gartner, Inc.

Gartner defines network performance monitoring and diagnostics as tools that “leverage a combination of packet data, flow data and infrastructure metrics to provide historical, real-time and predictive views into the availability and performance of the network and the application traffic running on it. NPMD tools also provide the diagnostic workflows and forensic data to identify the root causes of performance degradations, increasingly through artificial intelligence for IT operations (AIOps) functionality. Finally, NPMD tools provide insight into the quality of the end-user experience, based on network-derived performance data.”

The following providers have recently been named leaders in the Gartner Magic Quadrant for Network Performance Monitoring and Diagnostics. The report, which highlights and scores the top products in the industry, features these four tools as being cornerstones in the space. Each provider’s market share and product portfolios differ, which is what makes them interesting to the wider audience of cloud consumers. Niche and emerging vendors can only hope to replicate the kind of market presence that these providers have earned over a sustained period of time. Here we provide a brief blurb about each and links to product details so you can learn more.
