Use the tabs across the top of the screen to select another Endpoint view. Each view contains one or more data types: * **Local Networks**: **Network Access** and **Wireless**. * **Dynamic Tests**: **Network**. * **Scheduled Tests**: **HTTP** and **Network**. * **Real User Tests**: **Visited Pages** and **Network**. ### Snapshots {% hint style="info" %} Available in all Endpoint views. {% endhint %} The **Snapshot** menu contains the following options: * **Save a snapshot** opens the **Save a Snapshot** dialog. Configure the snapshot, and then select **Save**. * **View All Snapshots** opens the **Snapshots** dialog. Search the saved snapshots or browse the paginated table by snapshot name, deletion date, and creation date. Select a snapshot name to open its saved data. For more information, see [Endpoint Agent Test Snapshots](https://docs.thousandeyes.com/product-documentation/tests/sharing-test-data#endpoint-agent-test-snapshots). ### Test Selector {% hint style="info" %} Available for the **Scheduled Tests > HTTP**, **Scheduled Tests > Network**, and **Dynamic Tests > Network** views. {% endhint %} The **Test** dropdown shows enabled and disabled tests grouped by type. Use the search field to find a configured test. Select the test settings icon to open the selected test's configuration in a new tab. ### Global Filters {% hint style="info" %} Available in all Endpoint views. {% endhint %} Select **Add Filter** to apply global filters to the timeline and detailed results. Filter groups and fields change with the selected view and data type. They can include agent, network, destination, wireless, sample, and VPN attributes. The metric selector above the timeline is separate from **Add Filter**. It determines the metric displayed on the timeline and in the detailed results. See the article for each Endpoint view for its available global filters and metrics. ### Timeline {% hint style="info" %} Available in all Endpoint views. {% endhint %} The **Timeline** is the primary focus of all Endpoint views. It shows test data from the last 30 days, or the length of time the test has been enabled (whichever is the lesser value). Use the timeline controls to change or focus the displayed data: * Select **24h**, **7d**, or **14d** to change the visible time range. * Select a point to load that interval in the detailed results. * Drag across the timeline to focus on a narrower range. * Use the previous and next interval controls to move between intervals. Select the latest interval control to return to the most recent data. * Use the timeline selector to move or resize the highlighted time range. Changing the filters, data type, metric, or interval updates the detailed results. ### Timeline Selector {% hint style="info" %} Available in all Endpoint views. {% endhint %} The **Timeline Selector** shows the available data at a broader scale. Move or resize its highlighted section to focus the timeline on a window from 24 hours to 14 days. ## Secondary Section The sections below provide summary details of each of the dynamic tabs available for the various Endpoint views. ### BSSID Table {% hint style="info" %} Available for the **Local Networks > Wireless** view. {% endhint %} | Metric | Description | | ----------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | BSSID | The base station ID (BSSID) or MAC address of the wireless access point serving the Endpoint Agent. | | SSID | The service set identifier (SSID) of the wireless access point serving the Endpoint Agent. | | Location | The location of the Endpoint Agent. | | Number of Endpoints | The number of Endpoint Agents being served by the same wireless access point, determined by the number of agents with the same BSSID. | | Phy Mode | Describes which IEEE 802.11 specification standard is being used for the wireless connection, related to coverage range and speed optimization. | | Channel | The channel used for the wireless connection with the access point serving the Endpoint Agent. | | Throughput | The sum of transmitted and received bytes, converted to bits and divided by the five-minute (300-second) Local Networks reporting interval.

This panel is further divided into two sections: * Primary section * Secondary section The **primary section** provides a graphical view of the network path towards the target site. In addition, it also provides the following **Page Load** details: * **Response Time**: Also known as time-to-first-byte, this is the time from the beginning of the request (before DNS request) until the client receives the first byte of the response from the web server. * **Content Time**: The time it takes (once the main request has started) for the browser to fully load the HTML and build the DOM tree. External resources like pictures and stylesheets might not be fully loaded now. The **Content Time** is calculated using the following formula: `[Timestamp when the DOM finished building] - [Timestamp when the main request started]` * **Page Load Time**: This maps to the load event triggered when the web page is fully loaded and initialized. Generally, the page load time is higher than the content time. The **Page Load Time** is calculated using the following formula: `[Timestamp when the page, including the resources it refers to, is completely loaded and initialized] - [Timestamp when the main request started]` The **secondary section** provides additional agent and connection information broken into dynamic tabs based on the available data: * **Agent Info**: Provides information about the operating system, platform, OS version, browser details, network configuration (IP address, DNS servers), manufacturer, model, and memory information. * **Wireless Info**: Provides information on the Endpoint Agent's wireless connection, including signal quality, noise (only for macOS devices), and transmission rate. * **Path Trace**: A complete hop-by-hop path, with delay measured from the host machine running the Endpoint Agent to the targeted domain at each hop. The path trace is obtained using ICMP. Gateway and proxy nodes along the path are also shown. * **Redirects**: A list of all redirect URLs encountered along the path, and the time each took. * **Waterfall**: Provides detailed information about each object on the selected page, including object name, response code, domain, size, and the time taken to load the object. ### Path Visualization {% hint style="info" %} Available for the **Scheduled Tests > Network**, **Dynamic Tests > Network**, and **Real User Tests > Network** views. {% endhint %} The **Path Visualization** tab provides a graphical view of the network path, hop-by-hop, towards the target site. ![Path Visualization](https://1112912342-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M4QARF6s57qxMrOHDTZ%2Fuploads%2Fgit-blob-7f3b8d31ad1747f91527b01bad743c04b2c98d98%2Fproduct-documentation_global-vantage-points_endpoint-agents_endpoint-agent-views-reference-path-vis_1.png?alt=media\&token=a2c949f3-fad1-4345-8ccd-6036992ca18f) #### Grouping The **Grouping dropdown** can be used to configure the grouping of agents in visualization: ``` * Agents: Group agents based on * Network: Aggregate paths based on agent network. * ASN: Aggregate paths based on each combination of an agents's autonomous system number (ASN). * Private Network: Aggregate paths based on each combination of an agent's network. * Location: Aggregate paths based on each combination of an agent's geographical location. * Country: Aggregate paths corresponding to a country. * Agent: Individual path for each agent is visualized. * Interfaces: Group interfaces by * IP Address: Aggregate paths based on an interface IP addresses. * Network: Aggregate paths based on interface network. * Network & Location: Aggregate paths based on each combination of an interface's network and geographical location. * Location: Aggregate paths based on geographic location of interfaces. * ASN: Aggregate paths based on each combination of the interface's autonomous system number (ASN). ``` For more information on the path visualization, see [Path Visualization](https://docs.thousandeyes.com/product-documentation/internet-and-wan-monitoring/path-visualization/). ### Sessions {% hint style="info" %} Available for the **Real User Tests > Visited Pages** view. {% endhint %} The **Sessions** tab provides a table of all user sessions for the selected interval.

The percentage of packets lost is calculated by subtracting the number of reply packets the agent receives from the target (responses) from the number of packets sent by the agent, then dividing by the number of packets sent, then multiplying by 100. | | Latency | The average of the round-trip packet time. Round-trip packet time is the time from which a packet is sent by the agent to the time the agent receives a reply. | | Jitter | The mean deviation of latency. The mean deviation represents how far, on average, all measurements are from the mean of the data. | | Error Details | The detailed explanation for the error in connection. | | TCP Connect | Indicates if the agent was able to successfully establish the TCP connection. | #### Grouping within the Table {% hint style="info" %} Available for the **Dynamic Tests > Network** view. {% endhint %} ![Group By](https://1112912342-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M4QARF6s57qxMrOHDTZ%2Fuploads%2Fgit-blob-6ae4ab580c3144f70d98c755b2bae02c53939fec%2Fproduct-documentation_end-user-monitoring_viewing-data_endpoint-agent-views-reference-7.png?alt=media\&token=127baf48-24bd-4b98-93ee-f30e54c9da67) As a single Dynamic Test can target multiple different destinations (IP addresses) within the same test (for example, Webex), you can group the data in the table tab by **Agent** or by **Agent and IP addresses** to make it easier to identify the specific destinations affected by an incident. ## Additional Information ### User Experience Score The experience score rates a user's experience when loading a particular page. The score is calculated based on the time to load the DOM of a page, which is then mapped to a score based on our data set of load times. A score of 100 is the top score, 0 is the lowest score. An average experience is in the range of 44 to 89. Average (mean) experience scores can be displayed by Endpoint Agent, or by domain of pages visited. The ThousandEyes experience score is based on formulas and values that are not all visible in the product. Generally speaking, the score depends on a correlation function of page availability and content speed. While direct validation from the platform view is not fully realizable from the endpoint display, some quantities are shown in the platform view. A detailed break down is shown below. #### Experience Score The experience score (ES) is determined by the following formula: **ES = max( 0, PAS - (100 - SS) )** * The **max** function is to ensure that the experience score (ES) is always limited between 0 and 100. * The above formula allows future adding (or subtracting to be more accurate) impedances to the metric based on other factors (other than speed). * The experience score is defined per page. * PAS = Page availability score. * SS = Speed score. #### Page Availability Score The page availability score (PAS) is a binary score indicating the presence of one of the following errors during page load: * The server did not respond in time. * A browser error prevented the page from loading. * The server responded with an error (HTTP response code `4xx` or `5xx`). * The server responded successfully (HTTP response code `200`) but there was a browser error (e.g., loading an error page instead of the expected one). * Page load is successful otherwise. If an error occurs, `PAS = 0`. Otherwise, `PAS = 100`. {% hint style="info" %} This is irrespective of the speed of the page (the speed score). It also does not consider component errors, at least for now. {% endhint %} #### Speed Score The speed score is determined by the formula below: **SS = min( 0, 1 - ( ( Content Time + Redirect Time - X ) / Y ) ) )** * **Content Time**: Displayed in ms on the left side of the endpoint view. * **Redirect Time**: Displayed in ms on the left side of the endpoint view. If it is 0 it is not shown. * **X** and **Y** are based on the **OnContentLoad** time thresholds which are not visible in the display based on a linear correlation coefficient: | | | | | | --------- | --------------------------- | ----------------------------- | ---------------- | | Very Fast | : OnContentLoad <= 1s | → SS = 100 | → SS = 100 | | Fast | : 1s < OnContentLoad <= 2s | | → 89 <= SS < 100 | | Average | : 2s < OnContentLoad <= 6s | → SS = 100-100\*(CT-1)/(10-1) | → 44 <= SS < 89 | | Slow | : 6s < OnContentLoad <= 10s | | → 0 < SS < 44 | | Very Slow | : 10s < OnContentLoad | → SS = 0 | → SS = 0 |
