New Install. Showing no data on the agent dashboard

[rwright-bci]

Installed Grafana and checked the DB source, and had to create a copy of the dashboard to fix the TacticalURL and GrafanaURL variables (in order to save them).

I can bring up the dashboard but am not seeing any data

Here is a hover over the error:

Will I need to create a login for each of my techs to be able to view the dashboards in Grafana? Or is there a way to pass along the Tactical login as the user name?
