Incorrect number of hosts down reported #1076
Description
Grafana sometimes reports wrong number of hosts down when all nodes are shut down.
When I stop services tendrl-node-agent, collectd and tendrl-gluster-integration then for the first time grafana usually shows correctly that all nodes are down but if I start them and after a while I stop these services again then grafana reports that 4 hosts are down and 2 are up. This is happening consistently with multiple installation with 6 nodes.
