After I added a host to the cluster, the Agent Status for the new host is in bad health. I checked the Host Agent log and I see the following errors:   [07/Jan/2016 13:40:13 +0000] 407 MonitorDaemon-Reporter throttling_logger ERROR (9 skipped) Error sending messages to firehose: mgmt-SERVICEMONITOR Traceback (most recent call last): File "/usr/lib64/cmf/agent/src/cmf/monitor/firehose.py", line 116, in _send self._port) File "/usr/lib64/cmf/agent/build/env/lib/python2.6/site-packages/avro-1.6.3-py2.6.egg/avro/ipc.py", line 469, in __init__ self.conn.connect() File "/usr/lib64/python2.6/httplib.py", line 720, in connect self.timeout) File "/usr/lib64/python2.6/socket.py", line 567, in create_connection raise error, msg error: [Errno 111] Connection refused [07/Jan/2016 13:41:12 +0000] 407 MonitorDaemon-Reporter throttling_logger ERROR (9 skipped) Error sending messages to firehose: mgmt-HOSTMONITOR Traceback (most recent call last): File "/usr/lib64/cmf/agent/src/cmf/monitor/firehose.py", line 116, in _send self._port) File "/usr/lib64/cmf/agent/build/env/lib/python2.6/site-packages/avro-1.6.3-py2.6.egg/avro/ipc.py", line 469, in __init__ self.conn.connect() File "/usr/lib64/python2.6/httplib.py", line 720, in connect self.timeout) File "/usr/lib64/python2.6/socket.py", line 567, in create_connection raise error, msg error: [Errno 111] Connection refused   I couldn't find any existing solutions to this so I appreciate any help.   Thanks, Ali  ...
