The activity log provides a history of actions by the ThousandEyes users in your organization, including test creation, updates, deletions, login, logout, and other activities. The activity log also displays a timestamp and user metadata for each event.
In Internet Insights, an affected test is one of your ThousandEyes tests that is indirectly impacted, or could potentially be impacted, by an outage elsewhere in Internet Insights. A test can be affected even if that test is not showing any obvious errors or triggering alerts.
Agent refers to ThousandEyes software packages (servers) installed at specific global locations, used by customers to run tests against specified domains or targets. Agents are also referred to as global vantage points. Enterprise Agents are installed and maintained by customers inside their own networks, while Cloud Agents are maintained by ThousandEyes and are available to all customers. Endpoint Agents run on end-user computers and thus don't necessarily have a fixed location.
Agent clusters are multiple ThousandEyes Cloud and Enterprise Agents operating together to run ThousandEyes tests from a single location. Clustering simplifies the agent selection process and facilitates load balancing for new tests.
An alert rule is a condition or a set of conditions that you configure in order to highlight or be notified of events of interest in your ThousandEyes tests. When an alert rule’s conditions are met, the associated alert is triggered and the alert becomes active. It remains active until the alert is cleared. Alert rules are reusable across multiple tests.
With automated session tests, you can evaluate the performance of a desktop application without the need to manually set up an IP address or hostname. These tests function similarly to ThousandEyes agent-to-server scheduled tests, except that with automated session tests, ThousandEyes selects the endpoints to monitor. Used with Endpoint Agents.
Browser sessions is an Endpoint Agent feature that keeps track of how well websites perform when users access them from a monitored domain set. A browser session records both in-browser and network performance metrics.
A Cloud Agent is a ThousandEyes software agent that is available immediately to customers for running tests, with no administrative responsibilities. Cloud Agents provide globally distributed vantage points throughout the internet and are maintained by ThousandEyes.
The credentials repository is used in ThousandEyes Browser Synthetics transaction tests to store and control access to login credentials, while keeping secure strings, such as passwords, hidden.
ThousandEyes dashboards show customized live views of your test data, as well as Internet Insights collective intelligence. For example you can set up a dashboard based on Internet Insights that shows application outages related to your main SaaS provider, alongside internet outages that affect your users’ ability to access those domains.
ThousandEyes' device-layer monitoring uses Enterprise Agents to poll your network devices using the Simple Network Management Protocol (SNMP).
An embedded widget is a ThousandEyes dashboard widget that is referenced in the HTML source code of an external web page to make information available to viewers outside of your ThousandEyes organization. The embedded widget provides the same information via the external web page without requiring a ThousandEyes login.
Enabled applies to tests, agents, and alert rules.
- A ThousandEyes test that is enabled is actively running on one or more agents. Tests that are configured but not enabled do not consume units.
- An alert rule is enabled when it is applied to a particular test.
- A ThousandEyes agent is enabled when it is available for tests. If you disable an Enterprise Agent, you cannot run tests on it until you re-enable it.
The ThousandEyes Endpoint Agent is an application that is installed on end-user computers to measure network and application performance from the vantage point of a regular end user. Endpoint Agents can be deployed on- and off-premises to collect performance measurements from almost every possible user environment. Endpoint agents provide you with the ability to identify and diagnose end-user issues in near real-time.
Within WAN Insights, an endpoint pair refers to a connection between two routers located at different sites. From a data standpoint, WAN Insights endpoints are entities to which network traffic is routed, or which produce or consume traffic. Examples of endpoints include edge routers, SaaS data centers, and routing prefixes.
An Enterprise Agent is ThousandEyes software running on a Linux platform deployed and managed by a ThousandEyes customer for their exclusive use, to test targets from inside the customer's own network, or from within infrastructure under the customer's control. By contrast, ThousandEyes Cloud Agents are managed by ThousandEyes, shared by all customers, and are used for outside-in network testing.
Within WAN Insights, an impacted user refers to the end user of a business application within an enterprise network, who may be impacted by poor network performance.
An instant test is done using the Run Once button when configuring a new ThousandEyes Cloud or Enterprise Agent test, to validate the test configuration. Instant tests consume units, and thus they count towards monthly unit consumption.
ThousandEyes integrations allow you to use the ThousandEyes platform with other tools, to make the best use of ThousandEyes data for your organization. A common integration is to collect ThousandEyes alert notifications and display them in other communication systems such as Slack or PagerDuty.
ThousandEyes Internet Insights uses the collective intelligence of ThousandEyes’ entire agent network to show outages that may affect you, even if you’re not directly testing against those targets yourself. If enough ThousandEyes agents testing towards the same target report problems, ThousandEyes makes the inference that the cluster of errors represents a real outage and displays it on the Internet Insights > Outages map.
A test interval is the frequency at which a test is run. For example, every two minutes or every hour. Intervals are configured as part of each test’s settings.
A monitored domain set consists of domains that you want end-user performance monitoring information about. The best practice is to use business-relevant domains for tools and sites that your end users access. Used in Endpoint Agents > Browser Session Settings.
In a ThousandEyes test view, metrics are different measures that can be selected using a drop-down filter list. For example, a page load test might have page load time as one of the available metrics.
A notification generally refers to a message sent automatically upon certain events to your email, PagerDuty, Slack, AppDynamics, ServiceNow, or other tool configured through a custom webhook. Notifications apply to alerts, WAN Insights recommendations, usage limit notifications, and to ThousandEyes documentation updates.

An organization within ThousandEyes represents the overall billable entity.
Outages within Internet Insights refer to global events that impact a large number of servers or Autonomous Systems (AS).
- An application outage is an event for which some or all servers that belong to the same application are failing at the same point in time.
- A network outage is an event with 100% packet loss in the same Autonomous System (AS) and the same metropolitan location during the same period of time.
An overage is the result of exceeding your monthly unit allowance. Overages can be enabled or disabled for a particular customer. Customers with overages disabled are prevented from using more units than their monthly allowance. For those customers who have overages enabled, the overage may or may not be billed at the end of the month, depending on the customer's plan.
The WAN Insights Path Quality metric aggregates network performance measures (loss, latency, and jitter), and expresses the result as a single weighted percentage. This percentage expresses the likelihood of violating a defined quality threshold in the near future, which is a risk to be mitigated.
In Internet Insights, a package is a collection of Internet Insights providers with the same type and region, for example North America ISPs. Customers license a package in order to display outages originating from the providers included in the package.
For Internet Insights, a package license allows you to select a group of global providers to monitor. You can purchase multiple licenses and re-assign them as needed.
Within Internet Insights, a provider type refers to the primary service focus of various global connectivity providers, for example SaaS or ISP. For providers that might offer more than one type of service, the provider type is determined in part by the type of data that ThousandEyes is able to collect through various types of testing.
The Quality of Experience (QoE) score in WAN Insights is a calculated score based on aggregated Quality of Service (QoS) measurements for loss, latency, and jitter. Note that the QoE score indicates a level of risk, not an actual network outage.
Quality of Service (QoS) in WAN Insights measures network performance at the circuit level, between endpoint pairs. Quality of service is measured separately for loss, latency, and jitter, as a weighted percentage that expresses how close each performance measure is to its threshold.
Quotas are used to ensure that unit consumption, either at the organization or the account group level, does not exceed a defined monthly cap or threshold. If the quota is exceeded, you will not be able to set up new scheduled tests, and/or some scheduled tests may be automatically disabled in order to stop unit consumption.
A recommendation from WAN Insights refers to making network path or traffic routing changes at a particular network site in order to improve performance for a particular application category.
The ThousandEyes Recorder provides an integrated development environment (IDE) for creating, validating, and enhancing transaction test scripts based on your browser actions.
Users are assigned to roles, which have a set of permissions applied. The permissions determine how much functionality the user can partake of on the ThousandEyes platform. ThousandEyes has three default roles, though customers can create customized roles within their organization, too.
A saved event is a way to permanently save a time segment of test data. A saved event is similar to a snapshot, but is specific to a particular test, is private to your account group, and does not expire.
Shared by ThousandEyes refers to built-in test configurations provided by ThousandEyes. You can choose to activate or enable these tests for your own use.
- Dashboard snapshots represent a specific time range of the dashboard’s data. Snapshots can be created on demand, or created automatically according to a schedule and emailed to a list of recipients. See Dashboard Sharing and Snapshots for more information.
- For test data, the snapshot feature allows you to provide a URL to a read-only ThousandEyes test results web page at a specified point in time, viewable by anyone who has the link. See Sharing Test Data for more information.
A ThousandEyes test layer refers to layers of operation, but is not the same as the OSI 7-layer network model or the TCP/IP 4-layer model. The ThousandEyes test layers are Routing, Network, DNS, Web, and Voice. Test data over time is displayed in test views. Multiple test layers may be available within a single test view.
A test round refers to a single measurement performed by a ThousandEyes scheduled test, as executed by one or more ThousandEyes agents, for a single point in time. For example, for a test running at 5-minute intervals, a single test round might show test results for 12:00 midnight UTC, while the next round would show results for 12:05 am UTC.
A test timeout specifies how long to wait before assuming that the test target is unresponsive.
A transaction test script is used in ThousandEyes Browser Synthetics transaction tests that simulate a multi-step user journey through a web site, for example online shopping.
Units are the measure by which tests run on Cloud or Enterprise Agents are charged. Throughout the month, configured tests consume units against the customer's monthly unit allowance, which in turn impacts customer billing. Generally, customers cannot consume more units than their plan allows. Each test consumes a certain number of units based on the test type, interval, timeout, and the number and type of ThousandEyes agents running the test.
A ThousandEyes user is someone registered to use the ThousandEyes user interface and/or the API.
A ThousandEyes view refers to test data shown on a timeline. Every test in ThousandEyes has a Views screen, and each view has multiple view layers that represent different levels of networking, from the underlay all the way through HTTP and voice layers. There are views available under Cloud & Enterprise Agents, Endpoint Agents, Devices, and Internet Insights.
