Connection Close between Collector and Agent
I can see the collector instance was down between the particular time frame and in the collector instance log I can see the following line, could you please suggest what causing this issue.
2014-11-21 20:49:46 WARNING [Controller] Connection between controller and "agent agent" name closed.: com.dynatrace.diagnostics.collector.agentcenter.Controller a:644

Hi
I renamed and moved your question to the dynatrace Open Q&A forum.
To your question. This means that the physical connection between your Agent and this Collector was closed due to a Read Timeout. I think this typically happens when there is a problem with your agent, e.g: the application is no longer responding, it is crashed, ... and therefore our Agent is no longer responsive.
Can you look in the agent log files of that agent? You should find the log file on the machine where your agent is installed in the DTINSTALLDIR/log directory. Maybe there is an indication of what happened to that agent
