Comment 6 for bug 1545414

If you have data in Grafana it means that metrics are pushed and LMA is working at some point.

These error means that LMA is not pushing any data to Nagios. So you can check that Heka output for Nagios are started on the controller. In /var/log/lma_collector.log you should see:

2016/02/23 08:47:02 Output started: nagios_afd_nodes_output
2016/02/23 08:47:02 Output started: nagios_gse_global_clusters_output
2016/02/23 08:47:02 Output started: nagios_gse_node_clusters_output

without any errors after.

And then check that Nagios is working well on the monitoring node. Look in /var/log/nagios3/nagios.log
