Cumulus NetQ Overview

Cumulus NetQ Overview

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.

Cumulus 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 Cumulus NetQ deployed, you have a network-wide 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.

In summary:

Without NetQ With NetQ
Difficult to debug overlay network View network-wide status of overlay network
Hard to find out what happened in the past View historical activity with time-machine view
Periodically sampled data Real-time collection of telemetry data for a more complete data set

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 Cumulus 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.

In summary:

Without NetQ

With NetQ

Reactive to trouble tickets

Catch inconsistencies and misconfigurations prior to deployment with integrity checks/validation

Large amount of data and multiple tools to
correlate the logs/events with the issues

Correlate network status, all in one place

Periodically sampled data

Readily available historical data for viewing and correlating changes in the past 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. Cumulus 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:

Without NetQ

With NetQ

Large amount of data and multiple tools to
correlate the logs/events with the issues

Rolled up and correlated network status, view events and status together

Past events are lost

Historical data gathered and stored for comparison with current network state

Manual, box-by-box troubleshooting

View issues on all devices all at once, pointing to the source of the problem

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 Cumulus 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.

In summary:

Without NetQ With NetQ
Trace covers only data path; hard to check control path Both data and control paths are verified
View portion of entire path View all paths between devices all at once to find problem paths
Node-to-node check on misconfigurations View any misconfigurations along all hops from source to destination
