It allows you to isolate and analyze performance metrics for a single path over a selected time range. > [!TIP] > **Tip**: Subtests are automatically created based on the parent test's configuration (see [**Test Results**](/v1/docs/test-results)). Subtests are not explicitly created by Kentik portal users. ## Subtest Results Page UI This section describes the UI elements of the results page for an individual subtest. ### Subtest Results Main Controls - **Subtest Identifier**: A heading at the upper left of the page identifies the test by showing what it is testing from and toward. > [!NOTE] > **Notes:** When the from or toward is an agent: > > - An icon to the left of the agent name indicates whether it is a global or private agent. > - Text below the name displays the cloud region or AS name/number. > - A green checkmark indicates the agent is active, while a red exclamation mark indicates it is offline. - **Time Range:** A dropdown menu to select the lookback period (e.g., Last 1 Hour). - **Latest:** Jumps to the most recent data point. - **Details Tabs**: A set of tabs on the left (which vary depending on the [**test type**](/v1/docs/test-types)) that provide different test results views for the currently selected time slice. ### **Alert Timeline** The **Alert Timeline** provides a visual, interactive chart representing your subtest's data points and overall status over the selected time range (see [**Status Time and Scope**](/v1/docs/test-status-reference#status-time-and-scope)). By default, the latest time slice (far right) is selected, and for which details are given in charts in the [**Data Section**](/v1/docs/subtest-results#data-section). Hovering over the chart displays the exact timestamps for specific data points. ### **Data Section** A unified **Data** section presents the core performance metrics for an individual subtest. Depending on the test type, you can toggle between the following inline tabs: #### Time Series The **Time Series** tab displays a set of combination and line charts detailing the performance of this specific subtest over time. ![Subtest details for a Network Mesh test, with graphs showing average latency and packet loss over time.](https://cdn.us.document360.io/082e25b5-afce-42d4-8f47-70bd3f1d02b7/Images/Documentation/TCC-subtest-details-network-mesh.png?sv=2026-02-06&spr=https&st=2026-11-07T02%3A25%3A58Z&se=2026-11-07T03%3A25%3A58Z&sr=c&sp=r&sig=3xwA1WRWGcQmy7Ct3PUCR4UQ4%2FaGTx%2FFEA12zprVOL8%3D) - **Standard Metrics**: Includes Avg Latency (ms), Packet Loss (%), and Avg Jitter (ms), each displaying its Average, Minimum, and Maximum values. Depending on the test, it may also include a Traffic chart detailing inbound and outbound Kbps. - **Chart Behaviors During Failures**: When a test fails during a given period, the way it plots depends on the cause: - **Errors** (e.g., agent/OS error): Results in a gap in the plot for Latency, Jitter, and Packet Loss. - **Timeouts**: Results in a gap in the plot for Latency and Jitter, but Packet Loss will spike and be shown as 100%. - **Test-Specific Metrics**: Depending on the test type, additional charts will appear automatically: - **DNS Tests**: Displays DNS Results lozenges and a Resolution Time chart. - **HTTP(S) / API Tests**: Displays HTTP Stages Breakdown, Avg HTTP Latency, and HTTP Status Code charts. - **Page Load Tests**: Includes the HTTP charts above, plus a CSS Selectors chart showing a count of configured selectors found on the page. #### Path View The **Path View** tab graphically represents the hop-by-hop traceroute data specific to this individual subtest path. ![Critical alert showing packet loss and latency issues in network path view.](https://cdn.us.document360.io/082e25b5-afce-42d4-8f47-70bd3f1d02b7/Images/Documentation/TCC-subtest-details-network-mesh-path-view.png?sv=2026-02-06&spr=https&st=2026-11-07T02%3A25%3A58Z&se=2026-11-07T03%3A25%3A58Z&sr=c&sp=r&sig=3xwA1WRWGcQmy7Ct3PUCR4UQ4%2FaGTx%2FFEA12zprVOL8%3D) #### Waterfall (Page Load Tests) For a Page Load subtest, the **Waterfall** tab shows the load order and load duration of each element in the DOM (see [**Test Types Reference**](/v1/docs/test-types)). ![](https://cdn.us.document360.io/082e25b5-afce-42d4-8f47-70bd3f1d02b7/Images/Documentation/image(522).png?sv=2026-02-06&spr=https&st=2026-11-07T02%3A25%3A58Z&se=2026-11-07T03%3A25%3A58Z&sr=c&sp=r&sig=3xwA1WRWGcQmy7Ct3PUCR4UQ4%2FaGTx%2FFEA12zprVOL8%3D) - **Filtering**: Enter text in the **Filter** field to filter the resources shown in the table. Choose a scope of either **URL** or **Body** using the dropdown in the upper left. Use the Type Selector to isolate specific resource types (e.g., JavaScript, CSS, image), or toggle **Errors Only**. - **Visual Phases**: The download for each resource is represented in the **Waterfall** column as a horizontal bar broken into colored segments corresponding to different phases (stalled, DNS lookup, SSL, initial connection, request sent, waiting, content downloaded). Hovering over a bar reveals the exact duration of each phase. #### Results (Transaction Tests) The **Results** tab shows the total transaction completion time for a Transaction subtest. - **Transaction Completion Plot**: Individual transactions are plotted as dots. Passing transactions plot on the upper green PASS line, while failing transactions (timeouts) plot on the lower red FAIL line. - **Screenshots**: Displays visual captures taken at points specified in your Transaction test script (see [**About Transaction Test Scripts**](/v1/docs/transaction-test-scripts#about-transaction-test-scripts)). > [!NOTE] > **Note**: Screenshots will not be present for a given time slice if the health status during that time was Critical).
