Hortonworks Sandbox 2.6 - Heartbeat lost

[#1]

Hortonworks Sandbox 2.6 shows heartbeat lost. Tried restarting the ambari-agent, server. Tried almost everything on this forum. I removed the sandbox and installed 2.5, it is the same issue. Tried restarting all the services, nothing works.

Though there are no errors in ambari-agent, server, ambari-metrics-collector, I do see the following error on ambari-metrics-monitor log: Any help on this is much appreciated!

The errors which you posted does not look related to be related to Ambari Agent heartbeat lost.

Can you please share try restarting the ambari agent snad then share the agent log along with the ambari-server.log of the same time when the agent was restarted. (better to restart ambari-server and agent at once and share the logs)

# ambari-agent restart
# hostname -f
# ls -l /var/log/ambari-agent/ambari-agent.log
# ls -l /var/log/ambari-server/ambari-server.log
