According to the lma_collector.log, last entries show that the metrics can not be send to the LMA aggregator because the tcp input plugin related to the aggregator cannot use the port that is already used. So it is like a process is already using the port.
Have you try to stop lma (crm resource stop lma_collector on the controller), check that no heka process is running and start the lma_collector (crm resource start lma_collector). And send the /var/log/lma_collector.log log file.

So I set it to incomplete.
