This article walks you through assigning graphs to your multi-farm dashboard builder dashboard. Once you have created the graphs desired then you can organise these how you would like and that is covered in the next article linked at the bottom.
Assigning metrics or graphs to your multi-farm dashboard
1. Once you are in a dashboard, click Add Tile in green on the left.
2. Select Bar Chart or Time Series and click Create.
3. Enter a Name for the tile, your Chart Type and what Metric you want to be in the chart. You also can enter a custom title for the metric by clicking the edit button next to the metric box.
4. If you need to make tweaks to the tile that you have saved, you can click the three-dot button on the top right of the tile and click edit to re-open the update tile screen.
