Introduction to DANZ Monitoring Fabric

This chapter introduces the DANZ Monitoring Fabric (DMF) and the user interfaces for out-of-band monitoring and configuration.

 

Overview

DANZ Monitoring Fabric (DMF) is a cloud-first Network Packet Broker (NPB) that provides a single pane of glass with an integrated visibility fabric. The DMF solution includes NPB functionality with the DMF Recorder Node and the Analytics Node for deeper monitoring and pervasive security of out-of-band workloads in hybrid cloud deployments.

DMF leverages an SDN-controlled fabric using high-performance, open networking (white box/brite box) switches and industry-standard x86 servers to deploy highly scalable and flexible network visibility and security solutions. Traditional, box-based, hardware-centric NPBs are architecturally limited when trying to meet the evolving security and visibility demands of Cloud Native data centers. DMF addresses the challenges of traditional NPB solutions by enabling a scale-out fabric for enterprise-wide security and monitoring, a single pane of glass for operational simplicity, and multi-tenancy for multiple IT teams, including NetOps, DevOps, and SecOps.

Out-of-band Monitoring with DANZ Monitoring Fabric

As data center networks move toward 40/100G designs, cloud computing, hyper scale data analytics, and 5G mobile services, traffic monitoring must transition to next-generation designs. To manage the modern data center, much network traffic must be copied and aggregated from TAP or SPAN ports and forwarded to monitoring and analysis tools. These tools, used in managing network performance, application performance, security, and compliance, leverage other systems such as data recorders, intrusion detection systems, data leakage detectors, SLA measurement devices, and other traffic analyzers like Wireshark.

DANZ Monitoring Fabric (DMF) uses high-performance open-networking switches to deliver an open, production-grade, and scalable monitoring solution based on Software Defined Networking (SDN) technology. The centralized DMF Controller provides flexibility, simplifies policy management and monitoring fabric configuration, and supports cost-effective monitoring of data centers and remote sites or branches with up to several thousand TAP and SPAN ports.

DMF architecture, inspired by hyper scale networking designs, consists of the following components:

  • HA pair of SDN-enabled DMF Controllers (VMs or hardware appliances), enable simplified and centralized configuration, monitoring, and troubleshooting.
  • Arista Networks SDN-enabled Switch Light OS is a production-grade, ONIE-deployable, lightweight OS that runs on DMF Ethernet switches.
  • Open Ethernet switches (white box/brite box) use the same merchant silicon ASICs used by most incumbent switch vendors and are widely deployed in production data center networks. These switches ship with an Open Network Install Environment (ONIE) for automatic and vendor-agnostic installation of third-party network OS.
  • DANZ Service Nodes (optional), a Data Plane Development Kit (DPDK)-powered, x86-based appliances that connect to the DMF singly or as part of a service node chain. The service node provides advanced packet functions, such as deduplication, packet slicing, header stripping, regex matching, packet masking, UDP replication, and IPFIX/NetFlow generation.
  • DANZ Recorder Nodes (optional) are x86-based appliances connected to the DMF and are managed via the DMF Controller to provide petabyte packet recording, querying, and replay functions.
  • Analytics Nodes (optional) are x86-based appliances that integrate with the DMF to provide multi-terabit, security, and performance analytics with configurable, historical time-series dashboards.
Figure 1. Out-of-Band Monitoring with DANZ Monitoring Fabric
DMF lets a network operator easily deploy data center-wide monitoring with the following benefits:
  • Organization-wide visibility: delivers traffic from any TAP to any tool at any time across one or multiple locations.
  • Flexible, scale-out fabric deployment: supports a large number of 1G, 10G, 25G, 40G, and 100G ports (thousands per fabric).
  • Multi-tenant tap and tool sharing: supports monitoring by multiple teams to enable Monitoring Fabric as a Service.
  • Massive operational simplification: provides a single pane of glass for provisioning, management, monitoring, and debugging through a centralized SDN Controller. This feature eliminates the need for box-by-box configuration.
  • Centralized programmability: a REST-based API architecture enables event-based, centralized policy management and automation for integrated end-to-end IT work flows. This feature leverages DMF Service Nodes, Analytics Nodes, and Recorder Nodes.
  • Dramatic cost savings: Achieving a significant reduction in the total cost of ownership by using open Ethernet switches in combination with industry-standard x86 servers, optimized usage of tools, and SDN-enabled operations and automation.

Using the DANZ Monitoring Fabric CLI

Before connecting to the DANZ Monitoring Fabric (DMF) Controller, ensure the DMF application is running. Log in to the DMF Controller using the local console or SSH to the address assigned to the DMF Controller during installation.
Note: Make all fabric switch configuration changes using the Controller CLI, which provides configuration options in the config-switch submode for each switch. Do not log in to the switch to make changes directly using the switch CLI.
Mode and sub-modes divide CLI commands, which restrict commands to the appropriate context. The main modes and their available commands are as follows:
  • login mode: commands available immediately after logging in, with the broadest possible context.
  • enable mode: commands that are available only after entering the enable command.
  • config mode: commands that significantly affect system configuration and can only be entered after entering the configure command. The user can also access submodes from this mode.

Enter submodes from config mode to provision specific monitoring fabric objects. For example, the switch switchname command changes the CLI prompt to (config-switch)# and lets the user configure the switch identified by the switch name.

When the user logs in via SSH to the Controller, the CLI appears in login mode, where the default prompt is the system name followed by a greater than sign (>), as shown below: 
controller-1>
To change the CLI to enable mode, enter the enable command. The default prompt for enable mode is the system name followed by a pound sign (#), as shown below: 
controller-1> enable
controller-1#
To change to config mode, enter the configure command. The default prompt for config mode is the system name followed by (config)#, as shown below: 
controller-1> config
controller-1(config)#
To change to a submode, enter the command from config mode, followed by any object identifier required, as in the following example: 
controller-1(config)# switch filter-switch-1
controller-1(config-switch)# interface ethernet54
controller-1(config-switch-if)#
To return to enable mode, type end, as shown below: 
controller-1(config)# end
controller-1#
To view the path to the current CLI prompt, enter the show this command from any nested submode, as in the following example: 
controller-1(config-switch-if)# show this
! switch
switch filter-switch-1
interface ethernet54
To view details about the configuration, enter the show this details command, as in the following example: 
controller-1(config-switch-if)# show this details
! switch
switch filter-switch-1
!
interface ethernet54
no force-link-up
no optics-always-enabled
no shutdown
To view a list of available commands in the current or submode, enter the help command. 
controller-1> help
For help on specific commands: help <command>

Using the DANZ Monitoring Fabric GUI

The DANZ Monitoring Fabric (DMF) Graphical User Interface (GUI) performs similar operations to the CLI using a graphic user interface instead of text commands and options. The DMF GUI is compatible with recent versions of any of the following supported browsers:
  • Mozilla Firefox
  • Google Chrome
  • Microsoft Edge
  • Internet Explorer
  • Apple Safari

To connect to the DMF GUI, use the DMF Controller IP address. Use the virtual IP (VIP) assigned to the cluster if configured during deployment. Using the VIP ensures that the user connects to the current active Controller, regardless of any failover that may have occurred.

Use the active Controller for all configuration operations and to obtain reliable information when monitoring DMF. The standby Controller is provided only for redundancy if the active Controller becomes unavailable. Do not perform any configuration using the standby Controller, and any information displayed may not be accurate. The figure below illustrates connecting to the DMF GUI using HTTPS (port 443) at the IP address 192.168.17.233
Figure 2. Connecting to the DANZ Monitoring Fabric GUI
Connecting to the Controller for the first time may result in a security exception prompt (message) because the Controller HTTPS server uses an unknown (self-signed) certificate authority.
Note: When using Internet Explorer, the login attempt may fail if the system time is different than the Controller time. To remedy this, ensure the system used to log in to the Controller is synchronized with the Controller.
After accepting the prompts, the system displays the login prompt, shown in the figure below.
Figure 3. DANZ Monitoring Fabric GUI Login Prompt

Use the admin username and password configured for the DMF Controller during installation or any user account and password configured with administrator privileges. A user in the read-only group will have access to options for monitoring fabric configuration and activity but cannot change the configuration.

Figure 4. DANZ Monitoring Fabric GUI Main Menu
When logging in to the DMF GUI, a landing page appears. This page shows the DMF Controller Overview, dashboard, and a menu bar (pictured above) with sub-menus containing options for setting up DMF and monitoring network activity. The menu bar includes the following sub-menus:
