Unable to obtain metrics data from the server

In a OSB cluster, the application "ALSB Cluster Singleton Marker Application" is deployed only on ms1. This marker application tells on which server the Metrics Aggregator for OSB console should run.

If you start only ms2, you will get the message "Unable to obtain metrics data from the server", because no Aggregator is running. Not a big deal. As soon as you start ms1, the metrics will be available and the warning will go away.
