# `ExDataSketch.LiveDashboard.Page`
[🔗](https://github.com/thanos/ex_data_sketch/blob/main/lib/ex_data_sketch/live_dashboard/page.ex#L2)

A `Phoenix.LiveDashboard.PageBuilder` page listing every ExDataSketch
telemetry event, its measurements, and the `Telemetry.Metrics` names
`ExDataSketch.Telemetry.Metrics.all/1` derives from them.

This page is a static reference, not a live view of any particular
running sketch -- it has no way to know which `ExDataSketch.Server` or
`ExDataSketch.Sketches` instances a host application has started. For
live per-instance estimates, build an application-specific
LiveDashboard page (or a plain LiveView) that calls
`ExDataSketch.Server.estimate/2` on the instances your application
actually runs.

## Dependency

This module only exists when the optional `phoenix_live_dashboard`
dependency is loaded (`Code.ensure_loaded?/1` gates the whole module,
matching `ExDataSketch.Storage.Ecto`'s pattern). Add it to your
application:

    {:phoenix_live_dashboard, "~> 0.8"}

## Usage

    live_dashboard "/dashboard",
      additional_pages: [
        sketches: ExDataSketch.LiveDashboard.Page
      ]

# `init`
