## Introduction

In this how-to guide, we will describe how to build a Grafana dashboard for monitoring production lines in real time. This is:

1. [Line overview dashboard](docId\:TOQ-9h3b-AHk9PhCL3asf)
   A real-time dashboard for floor operators and shift leads, showing input tank levels, mixer status and storage tank state across all production lines simultaneously.

### Dashboard overview

### Line Overview Dashboard

The Line Overview Dashboard gives a single-screen view of the entire production line, from input tanks through the mixer to storage tanks. It introduces **panel repetition by variable**, where one panel definition automatically renders once per production line. It also covers the `Filter fields by name` and `Rename by regex` transformation pattern, which is essential whenever a query returns data for multiple assets at once and each repeated panel copy needs to isolate its own slice of that data.

### Prerequisites

Make sure you have the following prepared:

- An instance of Factry Historian.
  If you do not have an instance of Factry Historian at your disposal, you can run it locally using our [Docker setup guide](docId\:MYrFSdThXLh5xQK06iK-m).
- Data from Faketory loaded as measurements.
  Consult the [Docker setup guide](docId\:MYrFSdThXLh5xQK06iK-m) or the [Faketory](docId\:tJw2vWPK12gU3Z5AWHr4a) pages for more information.
- A configured Faketory [Asset tree](docId\:iN_ezeGWrOTYDEZ3cgrYE) and associated [Events](docId:9v8E0C-mKyeQdC85Wpd9H).
- Installed and configured [Factry Historian Datasource plugin for Grafana](docId:9enC3pgV14ed-p2oATbtJ).

We recommend loading all data for the Faketory in a separate organization in Factry Historian and configuring the datasource plugin against this organization.
