ThousandEyes monitors the performance of both local and wide-area networks. ThousandEyes combines Internet and WAN visibility, browser synthetics, end-user monitoring, and Internet Insights to deliver a holistic view of your hybrid digital ecosystem – across cloud, SaaS, and the Internet. It's a SaaS-based tool that helps troubleshoot application delivery and maps Internet performance.

Scope of support​

Currently, Nobl9 integration with ThousandEyes supports the following metrics:

  • Network Latency - is the interval time (in milliseconds) from sending a network packet to when the test-assigned agent receives the response.

  • Network Loss - is the total loss of the network packet (in percents).

  • Page Load - is the interval of time (in milliseconds) from the load event to the point when the website is loaded.

  • DOM Load Time - is the interval of time (in milliseconds) required for the browser to build the website’s Document Object Model (DOM)

  • HTTP Server Response - is the interval between the beginning of the request and the web server successfully sending the first byte of the response to the client.

  • HTTP Server Availability - is the availability for a given agent. For HTTP Server Availability, Nobl9 receives status codes of an http response, for example, 200, 201, 400, or 501.

    warning

    When there are multiple ThousandEyes agents, Nobl9 can receive multiple HTTP response status codes in a single request. In this situation, Nobl9 ingests only the highest status code.

  • HTTP Server Throughput - is the Wire Size divided by the Receive Time (in bits per second). For more information, refer to the ThousandEyes documentation.

  • HTTP Server Total Time - time (in milliseconds) of ThousandEyes agent receiving the last byte of your server's response.

  • DNS Server Resolution Time - time (in milliseconds) of ThousandEyes agent receiving the response from the DNS server about your domain.

  • DNS DNSSEC Valid - 1 if keychain for a domain record is valid, 0 otherwise.

Each measurement is obtained per ThousandEyes test interval.

warning

Whenever your ThousandEyes SLO has incompatible data source version/channel, the SLO config won't be served to your data source.

Authentication​

Nobl9 requires OAUTH_BEARER_TOKEN to communicate with ThousandEyes.

To get the OAUTH_BEARER_TOKEN:

  1. Log in to your ThousandEyes account.

  2. Navigate to Account Settings.

  3. Select Users and Roles.

  4. Navigate to the bottom of the page and you will see User API Tokens.

  5. Select OAuth Bearer Token.
    Currently, Nobl9 only supports OAUTH_BEARER_TOKEN.

Adding ThousandEyes as a data source​

To ensure data transmission between Nobl9 and ThousandEyes, it may be necessary to list Nobl9 IP addresses as trusted.

IP addresses to add to your allowlist:
  • 18.159.114.21
  • 18.158.132.186
  • 3.64.154.26
⚠ Applies to app.nobl9.com only. In all other cases, contact Nobl9 support.

You can add the Thousandeyes data source using the direct or agent connection methods. For both methods, start with these steps:

  1. Navigate to Integrations > Sources.
  2. Click .
  3. Click the relevant Source icon.
  4. Choose a relevant connection method (Agent or Direct), then configure the source as described below.

Direct connection method​

Nobl9 Web​

Direct configuration for ThousandEyes requires users to enter their credentials which Nobl9 stores safely. Follow these steps to set up a direct configuration:

  1. Select one of the following Release Channels:
    • The stable channel is fully tested by the Nobl9 team. It represents the final product; however, this channel does not contain all the new features of a beta release. Use it to avoid crashes and other limitations.
    • The beta channel is under active development. Here, you can check out new features and improvements without the risk of affecting any viable SLOs. Remember that features in this channel may be subject to change.
  2. Enter your OAuth Bearer Token.
    Refer to the Authentication section above for more details.

  1. Select a Project.
    Specifying a project is helpful when multiple users are spread across multiple teams or projects. When the Project field is left blank, Nobl9 uses the default project.
  2. Enter a Display Name.
    You can enter a user-friendly name with spaces in this field.
  3. Enter a Name.
    The name is mandatory and can only contain lowercase, alphanumeric characters, and dashes (for example, my-project-1). Nobl9 duplicates the display name here, transforming it into the supported format, but you can edit the result.
  4. Enter a Description.
    Here you can add details such as who is responsible for the integration (team/owner) and the purpose of creating it.
  5. Specify the Query delay to set a customized delay for queries when pulling the data from the data source.
    • The default value in ThousandEyes integration for Query delay is 1 minute.
    info
    Changing the Query delay may affect your SLI data. For more details, check the Query delay documentation.
  6. Click Add Data Source.

You can deploy only one agent in one YAML file by using the sloctl apply command.

Agent deployment​

When you add the data source, Nobl9 automatically generates a Kubernetes configuration and a Docker command line for you to use to deploy the agent. Both of these are available in the web UI, under the Agent Configuration section. Be sure to swap in your credentials (e.g., replace <OAUTH_BEARER_TOKEN> with your actual token).

If you use Kubernetes, you can apply the supplied YAML config file to a Kubernetes cluster to deploy the agent. It will look something like this:

# DISCLAIMER: This deployment description contains only the fields necessary for the purpose of this demo.
# It is not a ready-to-apply k8s deployment description, and the client_id and client_secret are only exemplary values.

Creating SLOs with ThousandEyes​

Nobl9 Web​

Follow the instructions below to create your SLOs with ThousandEyes in the UI:

  1. Navigate to Service Level Objectives.

  2. Click .
  3. In step 1 of the SLO wizard, select the service the SLO will be associated with.

  4. In step 2, select ThousandEyes as the data source for your SLO, then specify the Metric. For ThousandEyes you can use only a threshold metric, where a single time series is evaluated against a threshold, The ThousandEyes metric specification has two fields: testID and testType.

    • Enter a testID. It is an ID of the test configured in ThousandEyes. It is a mandatory field, and it must be a positive number.

    • Choose a testType. It is a ThousandEyes metric. You can choose between the following ThousandEyes metrics supported by Nobl9 (refer to the Scope of support section for more details):

      • Network Latency

      • Network Loss

      • Page Load

      • DOM Load Time

      • HTTP Server Response

      • HTTP Server Availability

      • HTTP Server Throughput

  5. In step 3, define a Time Window for the SLO.

  • Rolling time windows are better for tracking the recent user experience of a service.

  • Calendar-aligned windows are best suited for SLOs that are intended to map to business metrics measured on a calendar-aligned basis, such as every calendar month or every quarter.

  1. In step 4, specify the Error Budget Calculation Method and your Objective(s).

    • Occurrences method counts good attempts against the count of total attempts.
    • Time Slicesmethod measures how many good minutes were achieved (when a system operates within defined boundaries) during a time window.
    • You can define up to 12 objectives for an SLO. For more information, check the Composite SLOs Guide.

    See the use case example and the SLO calculations guide for more information on the error budget calculation methods.

  2. In step 5, add the Display name, Name, and other settings for your SLO:

    • Create a composite SLO
    • Set notification on data, if this option is available for your data source.
      When activated, Nobl9 notifies you if your SLO hasn't received data or received incomplete data for more than 15 minutes.
    • Add alert policies, labels, and links, if required.
      You can add up to 20 links per SLO.
  3. Click Create SLO.

Important notes:

The ThousandEyes metric specification expects two fields: testID and testType.

  • testID is an ID of the test configured in ThousandEyes. It is a mandatory field, and it must be a positive number.

  • testType is an end-to-end ThousandEyes metric. It is a string field. Enter one of the below ThousandEyes metrics supported by Nobl9 (for more details, refer to the Scope of support section above).

    • net-latency

    • net-loss

    • web-page-load

    • web-dom-load

    • http-response-time

    • http-server-availability

    • http-server-throughput

When the testType field is missing in the ThousandEyes YAML configuration, net-latency value is assumed.

caution

If you want to apply http-server-availability and http-server-throughput as testType, update your agent to the 0.52.0 version.

Querying the ThousandEyes server​

Nobl9 queries the ThousandEyes instance once every minute. If the agent doesn’t collect any data in a given minute, the next query will be extended to the past two minutes.

ThousandEyes API rate limits​

The ThousandEyes API throttles API requests using a 240 request-per-minute (per organization) limit with each page having max 1000 elements included.
