ThousandEyes Integration

Cisco IOS XE 17.18.1

ThousandEyes is a cloud-ready, enterprise network-monitoring tool that provides an end-to-end view across networks and services.

  • In Cisco IOS XE 17.18.1, this feature was implemented on Cisco Catalyst 9350 Series Switches.

Prerequisites for the ThousandEyes Enterprise Agent

  • The ThousandEyes Enterprise Agent image available at the ThousandEyes site must be signed by the same certificate authority (CA) that is used by www.cisco.com for HTTPS downloads; without an username or a password.

  • Installation of the Enterprise Agent requires Internet connectivity, or a proxy server. For more information, see the ThousandEyes documentation at: https://docs.thousandeyes.com/product-documentation/enterprise-agents.

  • The Enterprise Agent application can only be used after the user’s license privileges are validated.

  • Only Docker-based applications are supported.

  • 1:1 stack mode is a must for ThousandEyes Stateful Switchover (SSO) support.

    1:1 mode is when the active and standby roles are assigned to specific devices in a stack. This overrides the traditional N+1 role selection algorithm, where any device in the stack can be the active or the standby.

Information About ThousandEyes Enterprise Agent

ThousandEyes Enterprise Agent Overview

ThousandEyes Enterprise Agent is an enterprise network-monitoring tool that provides you an end-to-end view across networks and services that impact your business. It monitors the network traffic paths across internal, external, carrier, and Internet networks in real time, to provide network performance data. Enterprise Agents are commonly installed in branch sites and data centers to provide a detailed understanding of WAN and Internet connectivity.

In previous Cisco IOS XE releases, ThousandEyes was supported as a third-party Kernel-based Virtual Machine (KVM) appliance on the SSD.

In Cisco IOS XE 17.18.1, a new version of the ThousandEyes Enterprise Agent, Version 3.0 is introduced. This is an embedded Docker-based application that runs on Cisco devices using the application-hosting capability. The Enterprise Agent is available on both the SSD and bootflash, and it supports all tests except browser tests (page load and transaction). The browser tests are available in Cisco IOS XE 17.18.1 and later releases with Enterprise Agent Version 4.0.

The ThousandEyes Enterprise Agent provides the following:

  • Benchmarking the performance of networks and applications.

  • Detailed hop-by-hop metrics.

  • End-to-end path visualization from branch or campus to data center or cloud.

  • Outage detection and resolution.

  • User-experience analysis.

  • Visualization of the traffic-flow pattern.

ThousandEyes Enterprise Agent Version 4.0 available in Cisco IOS XE 17.18.1, supports the following additional features that are not available in the ThousandEyes Agent Version 3.0:

  • BrowserBot support when back-panel SSD is available.

  • DNAC app icon and description.

  • Docker health monitoring.

  • The app-hosting upgrade URL command to upgrade the ThousandEyes Enterprise Agent.

ThousandEyes Enterprise Agent Download

BrownField and GreenField are two types of ThousandEyes Enterprise Agents. For existing devices, you can download the Brownfield version from the ThousandEyes website. However, new devices are shipped with the Greenfield application loaded in the bootflash.

This table lists the download options available for the agents.

Table 3. ThousandEyes Enterprise Agent Download Options

BrownField

GreenField

  • Download the file from the Installing Enterprise Agents on Cisco Switches with Docker page. The file is signed by the same certificate authority (CA) that is used by www.cisco.com for HTTPS downloads; without an username or a password.

  • Use the install command to download and deploy the application.

  • Available in the bootflash under the /apps folder. Shipped with the device.

  • Use the install command to download and deploy the application.

This section describes the maximum resources required for the agent to run:

  • CPU: 2 vCPUs

  • Memory: 2G

  • Storage: 1G for persistent logging by applications, out of the 4G partition in the flash file system. This storage is shared by the IOx metadata.

  • Media storage:

    • 120G SSD for Cisco Catalyst 9350 Series Switches in Cisco IOS XE 17.18.1.

After the download of the Enterprise Agent, it initiates a call to create a secure channel to the ThousandEyes cloud-based portal that provides the required application configuration, and gathers application data. The link to the TE portal is https://app.thousandeyes.com.

ThousandEyes BrowserBot

ThousandEyes Enterprise Agent Version 4.0 provides a BrowserBot for transaction scripting test. The BrowserBot is a component of the Enterprise Agent that manages page load and transaction tests. The BrowserBot allows you to enable customized JavaScript tests which mimic the actions of your web browser on the ThousandEyes Cloud Portal. To protect the host operating system from any errant JavaScript operations, the ThousandEyes agent creates sandbox containers to run your JavaScript.

If an unrestricted disk is used by the application, the ThousandEyes agent will dynamically install the BrowserBot package during initialization that permits portal transaction scripting tests to be configured.


Note

The BrowserBot support is not available in ThousandEyes Agent Version 3.0.

BrowserBot consumes a large amount of hardware resources. 2GB system memory and 2 VCPU loads are the maximum IOx system memory and CPU load allocated for all IOx apps. To allow multiple apps to concurrently run in the bootflash, lower the default package.yaml BrowserBot resources before activating the agent. Use the app-resource profile custom command to override the default package.yaml settings:

  • CPU:1850 CPU units (1/4 VCPU)

  • Memory: 500MB

For more information on transaction scripting, see the following links:

For examples of transaction scripting, see https://github.com/thousandeyes/transaction-scripting-examples.

ThousandEyes Agent Upgrade and Downgrade

ThousandEyes Agent Upgrade

Agent 4.0 is available in Cisco IOS XE 17.18.1, and the agent auto-upgrade updates to the latest Agent 4.0 binary on startup. No upgrade is available for Agent 4.0 at present.

Application upgrades can be done using the following methods:

  • ThousandEyes agent auto-upgrade: Happens automatically when an application starts up. The agent binary within the running container is upgraded, but the application package is not upgraded.

  • Using the app-hosting upgrade command.

  • DNAC app upgrades.

ThousandEyes Agent Downgrade

Agent 4.0 available in Cisco IOS XE 17.18.1 can be downgraded to Agent 3.0 available. No other downgrade is possible.

When downgrading, if the application does not come to the same state as the previous release, deactivate or uninstall the application, and install or restart it.
