Hi Jaroslaw,

Once you were able to show the edges between nodes in your Node Edge diagram, you will need to enhance the query used as edge to include the KPIs that you are looking for.

For this case you will need to the following tables:

• The table that contains the KPIs (retrieved using the data source Get parameter for elements where, or Get parameter table by ID)
• The DCF Interfaces (retrieved using the data source Get DCF Interfaces)
• The DCF connections

Starting from this mockup:

You will notice that the Edge table contains an extra column (Interface state) which is a KPI from the interface.

This table was built as follows:

• Getting the KPI using the data source: Get parameter for elements where. You will get something similar to:
  
• Perform an Inner join with DCF Interfaces (retrieved using the data source Get DCF Interfaces). When selecting the columns that establish the relationship between these two tables, you should choose the column Dynamic PK from DCF Interfaces:
  
• Perform an Inner join with DCF Connections (retrieved using the data source Get DCF Interfaces). When selecting the columns that establish the relationship between these two tables, you should choose the column 'Source Interface ID' from DCF Connections:
  

When clicking in the edge you should get something similar to:

Finally, if you just want to display a specific parameter, you can use as filter the parameter from the query:

Below you can see the final result:

Hope it helps!
