Gartner Magic Quadrant for Network Performance Monitoring and Diagnostics (2017, 2016, 2015, 2014 )


According to Gartner, Network performance monitoring and diagnostics (NPMD) enable network professionals to understand the impact of network behavior on application and infrastructure performance, and conversely, via network instrumentation. Other users and use cases exist, especially because these tools provide insight into the quality of the end-user experience.

The fast-growing network performance monitoring and diagnostics market is helping businesses support more complex environments and services through network visibility, performance issue detection and root cause analysis.

Leaders in this industry are innovating around cloud-based monitoring, better support for software-defined environments and more flexible deployment models, according to research firm Gartner. The research firm estimates that the network performance monitoring and diagnostics tool market, which is a segment of the lager network management space, sits at $1.6 billion and is growing at a compound annual growth rate of 20.7 percent.

NetScout (Formerly is Fluke) , Viavi (formerly is JDSU) and Riverbed are leaders in the Gartner NPMD Magic Quadrant for the fourth consecutive year.

Gartner Magic Quadrant for Data Center Infrastructure Management (DCIM) (2016, 2015,2014)


Data center infrastructure management (DCIM) tools monitor, measure, manage and/or control data center resources and energy consumption of both IT-related equipment (such as servers, storage and network switches) and facilities infrastructure components (such as power distribution units [PDUs] and computer room air conditioners).

Based on Gartner report on Oct 2016, Nlyte Software, Emerson Network Power, and Schneider Electric continue to lead in the DCIM software market.

Avocent® ACS 8000 Advanced Console System Configuration


My company has used Avocent ACS (Advanced Console Server) to do network devices' console management for many years already. I were using 4000, 5000 and 6000 serie, and now 8000 series is coming to refresh some old ones.

Emerson (EMR) acquired infrastructure management specialist Avocent Corporation (AVCT) for $1.2 billion on Oct 2009. Since then Emerson combined its Aperture and new Avocent businesses as a new division focused on helping data center customers better manage their infrastructure. Now it is part of Vertiv which launched as standalone business. The Vertiv's Trellis DCIM platform was the first to use real-time data to enhance data center management and has been recognized as a leader in every DCIM Magic Quadrant published by Gartner.

Interesting thing is I even could not find Avocent product from Vertiv's product page. Totally there are 13 products under IT management category, but ACS product line is not there. I managed to google and find one link which shows more this product at this link:

Gartner Magic Quadrant for WAN Optimization (2016, 2015, 2014, 2013, 2012, 2011)


WAN optimization provides a range of features to: (1) improve the performance of applications running across the WAN; and (2) reduce the cost of the WAN. The range and scope of features supported byWAN optimization solutions continue to evolve, typically in support of three high-level needs: Improve the response times as experienced by users of business-critical applications over WAN links or mobile connections, often addressing application performance problems caused by bandwidth constraints, latency or protocol…

Gartner Magic Quadrant for Application Delivery Controllers (2016, 2015,2014,2013,2012,2010)


Application delivery controllers (ADCs) are generally deployed in the data center and provide functions that optimize delivery of enterprise applications across the network. ADCs provide functionality for both user-to-application and application-to-application traffic. The ADC effectively bridges the gap between the application and underlying protocols and the traditional packet-based networks. The market evolved from load-balancing systems that were developed in the latter half of the 1990s to ensure the availability and scalability of websites. Enterprises use…
