# Troubleshooting with Dashboard Drill Down

Dashboards are a critical tool in troubleshooting issues as they often immediately illustrate problems in your environment and are a starting point for further investigation.

With the **Drill Down** feature on the dashboard, you can easily navigate the platform and pinpoint a problem on the dashboard and quickly access the relevant tests, configured with proper filters and agents. This straightforward workflow enhances your ability to promptly troubleshoot issues as they arise.

A common way to utilize this feature is to quickly address issues in a NOC setting with the help of ThousandEyes.

## Workflow of the Dashboard Drill Down

In the dashboard, left-click a data point to open the drill-down panel and view the tests or other records associated with the widget, along with relevant context. For tooltip, drill-down, and context-menu behavior on Breakdown charts, see [Chart interactions and context menu](#chart-interactions-and-context-menu).

For the **Line** chart in a Time Series widget, left-click a data point to drill down into the line under your pointer. If multiple lines overlap at the same timestamp, right-click the data point and select the series you want to investigate. Hover over a context-menu entry to highlight its line before selecting the drill-down action. These interactions do not apply to Stacked Area or Box-and-Whiskers charts.

In this pop-up screen, you can select the test you want to view or combine multiple tests into a multi-service view. The ability to filter the views by multiple agents is only supported in Views 2.0. If you are drilling into Views 1.0, the specific agent context is not maintained. Also, the multi-service view is supported only for Cloud and Enterprise agents.

{% hint style="info" %}
If you need to find a specific test related to a widget with numerous tests, use the search field to locate and select it.
{% endhint %}

After you select, a new tab will open and redirect you to the chosen test view with the appropriate contextual information.

The tests displayed in this new tab will have the appropriate filters found in the widget.

You can drill down from any widget to the following areas:

* Network & App Synthetics > Views, either multi-service or individual tests (BGP tests are not supported).
* Endpoint Experience > Views for Scheduled Tests, Browser Sessions, and Local Networks.
* Devices.
* Cloud Insights.
* Traffic Insights.

{% hint style="info" %}
When using Endpoint Browser Sessions or Local Networks, the drill-down component will display the data's grouping as no associated test exists.
{% endhint %}

When using the drill-down component, the system will create a URL with appropriate filters and launch a new tab displaying the corresponding view as you select specific tests. However, please note that this URL has a character limit of 8000. If your selections result in a URL that exceeds this limit (which can happen if too many agents or filters are chosen), a warning message will appear. To prevent this issue, we suggest filtering agents or tests by labels rather than selecting individual ones.

### Chart interactions and context menu

On a live dashboard, use the following interactions with **Stacked Bar**, **Grouped Bar**, and **Pie** charts.

| Interaction                                                       | Result                           |
| ----------------------------------------------------------------- | -------------------------------- |
| Hover over a bar, stacked segment, or pie slice                   | Shows its values and context.    |
| Left-click the data point                                         | Opens the drill-down panel.      |
| Right-click the data point                                        | Opens the context menu.          |
| Choose **Drilldown**                                              | Opens the same drill-down panel. |
| Expand **Filter by**, then select a supported dimension and value | Applies a dashboard filter.      |

Unsupported filters are disabled in the menu. For a data point grouped by test, right-click it, expand **Filter by > Tests**, and select a test value such as **bbot\_canary\_web\_transaction**. The dashboard filter bar then shows **Tests: bbot\_canary\_web\_transaction**.

The drill-down panel might display a notice when a metric or grouping cannot be carried into the underlying Views page. This does not prevent the panel from opening.

#### Grouped Bar interaction examples

Hover over a bar to see its values for the continent and test series.

![Grouped Bar tooltip showing HTTP Total Time values for Europe and its test series](https://1112912342-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M4QARF6s57qxMrOHDTZ%2Fuploads%2Fgit-blob-50497121335cb4a6ec8f617e77760ce6f68abf0c%2Fdashboard-grouped-bar-tooltip.png?alt=media)

Left-click a data point to open the drill-down panel for its continent and test.

![Grouped Bar drill-down panel showing the selected Europe test](https://1112912342-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M4QARF6s57qxMrOHDTZ%2Fuploads%2Fgit-blob-182a53364b95af73cf4050566b0903109c4297fe%2Fdashboard-grouped-bar-drilldown-panel.png?alt=media)

Right-click a data point to open the context menu. Choose **Drilldown** to open the drill-down panel, or expand **Filter by** to see available filters.
