# system.dashboards

<h2 id="description">
  Description
</h2>

Contains queries used by `/dashboard` page accessible though [HTTP interface](/concepts/features/interfaces/http).
This table can be useful for monitoring and troubleshooting. The table contains a row for every chart in a dashboard.

<Note>
  `/dashboard` page can render queries not only from `system.dashboards`, but from any table with the same schema.
  This can be useful to create custom dashboards.
</Note>

<h2 id="columns">
  Columns
</h2>

* `dashboard` ([String](/reference/data-types)) — The dashboard name.
* `title` ([String](/reference/data-types)) — The title of a chart.
* `query` ([String](/reference/data-types)) — The query to obtain data to be displayed.
