# system.dashboards

<div id="description">
  ## Descrição
</div>

Contém consultas usadas pela página `/dashboard`, acessível por meio da [interface HTTP](/pt-BR/concepts/features/interfaces/http).
Esta tabela pode ser útil para monitoramento e troubleshooting. A tabela contém uma linha para cada gráfico em um dashboard.

<Note>
  A página `/dashboard` pode renderizar consultas não apenas de `system.dashboards`, mas de qualquer tabela com o mesmo schema.
  Isso pode ser útil para criar dashboards personalizados.

* `dashboard` ([String](/pt-BR/reference/data-types/index)) — O nome do dashboard.
* `title` ([String](/pt-BR/reference/data-types/index)) — O título do gráfico.
* `query` ([String](/pt-BR/reference/data-types/index)) — A consulta para obter os dados a serem exibidos.
