NetQ Overview

NVIDIA Cumulus NetQ is a highly scalable, modern network operations tool set that provides visibility and troubleshooting of your overlay and underlay networks in real-time. NetQ delivers actionable insights and operational intelligence about the health of your data center - from the container, virtual machine, or host, all the way to the switch and port. NetQ correlates configuration and operational status, and instantly identifies and tracks state changes while simplifying management for the entire Linux-based data center. With NetQ, network operations change from a manual, reactive, box-by-box approach to an automated, informed and agile one.

NetQ performs three primary functions:

• Data collection: real-time and historical telemetry and network state information
• Data analytics: deep processing of the data
• Data visualization: rich graphical user interface (GUI) for actionable insight

NetQ is available as an on-site or in-cloud deployment.

Unlike other network operations tools, NetQ delivers significant operational improvements to your network management and maintenance processes. It simplifies the data center network by reducing the complexity through real-time visibility into hardware and software status and eliminating the guesswork associated with investigating issues through the analysis and presentation of detailed, focused data.

Demystify Overlay Networks

While overlay networks provide significant advantages in network management, it can be difficult to troubleshoot issues that occur in the overlay one box at a time. You are unable to correlate what events (configuration changes, power outages, etc.) may have caused problems in the network and when they occurred. Only a sampling of data is available to use for your analysis. By contrast, with NetQ deployed, you have a networkwide view of the overlay network, can correlate events with what is happening now or in the past, and have real-time data to fill out the complete picture of your network health and operation.

Protect Network Integrity with NetQ Validation

Network configuration changes can cause numerous trouble tickets because you are not able to test a new configuration before deploying it. When the tickets start pouring in, you are stuck with a large amount of data that is collected and stored in multiple tools making correlation of the events to the resolution required difficult at best. Isolating faults in the past is challenging. By contract, with NetQ deployed, you can proactively verify a configuration change as inconsistencies and misconfigurations can be caught prior to deployment. And historical data is readily available to correlate past events with current issues.

Troubleshoot Issues Across the Network

Troubleshooting networks is challenging in the best of times, but trying to do so manually, one box at a time, and digging through a series of long and ugly logs make the job harder than it needs to be. NetQ provides rolled up and correlated network status on a regular basis, enabling you to get down to the root of the problem quickly, whether it occurred recently or over a week ago. The graphical user interface makes this possible visually to speed the analysis.

In summary:

Track Connectivity with NetQ Trace

Conventional trace only traverses the data path looking for problems, and does so on a node to node basis. For paths with a small number of hops that might be fine, but in larger networks, it can become extremely time consuming. With NetQ both the data and control paths are verified providing additional information. It discovers misconfigurations along all of the hops in one go, speeding the time to resolution.
