The Child FMS displays the data fine but the Federator does not populate the dashboard. Checking the data in the data browser or the Script Console indicates the data is current in the Federator.
When a Federation Master is asked to run a batch data query for "Last N" values it appears to always return empty result lists for those topology bjects that come from child server. Local topology objects work fine.
