From the Federation Master, if you press the "Diagnose" link from the End User Overview : Services at location <location name>, no data comes up. But data comes up on the FMS child for this same dashboard.
The issue is logged as EU-593.
The problem is caused by a lack of information about the FxM agents on the Federation Master.
Since the Agent information is not federated and the links build a URL from the agent info then the links do not work from the master.
For environments that have a single tier approach which runs as a standalone, or a probe-portal architecture where multiple probes report into a single portal, it might be possible to edit the view to just use a fixed URL instead of using the Agent information to create the URL.
The easiest way to accomplish this would be to edit the getFxMApplianceURL function located in the FxM submodule.
A new first line could be added that simply returned a string containing the FxM appliance's protocol and host name. So something like:
This change would have to be re-applied if the cartridge is upgraded.
Waiting for fix in a future release of Foglight
