  • EAP 6.4.15

Common Causes of Troubles

  • BLOCK policy. The queues seize up.
  • Always keep an eye on memory - automate gc log processing and failure detection.

Tracing Connection Creation

  • Set "org.hornetq.core.server" to TRACE.
  • Look for:
15:26:20,189 TRACE [org.hornetq.core.server] (Old I/O server worker (parentId: 1444597516, [id: 0x561acf0c, /127.0.0.1:5445]), runningThread=Thread-1 (HornetQ-remoting-threads-HornetQServerImpl::serverUUID=1dce22c5-4700-11e7-88d5-53aa0b02fcd0-1887100554-1781384206)) Connection created org.hornetq.core.remoting.impl.netty.NettyConnection@14335f60[local= /127.0.0.1:5445, remote=/127.0.0.1:49365]

Tracing Session Creation

  • Set "org.hornetq.core.client" to TRACE.
  • Look for:
15:26:50,240 TRACE [org.hornetq.core.client] (Old I/O server worker (parentId: 1444597516, [id: 0x561acf0c, /127.0.0.1:5445]), runningThread=Thread-2 (HornetQ-remoting-threads-HornetQServerImpl::serverUUID=1dce22c5-4700-11e7-88d5-53aa0b02fcd0-1887100554-1781384206)) handling packet PACKET(CreateSessionMessage)[type=30, channelID=1, packetObject=CreateSessionMessage]

15:26:50,245 TRACE [org.hornetq.core.client] (Old I/O server worker (parentId: 1444597516, [id: 0x561acf0c, /127.0.0.1:5445]), runningThread=Thread-2 (HornetQ-remoting-threads-HornetQServerImpl::serverUUID=1dce22c5-4700-11e7-88d5-53aa0b02fcd0-1887100554-1781384206)) Sending packet nonblocking PACKET(CreateSessionResponseMessage)[type=31, channelID=1, packetObject=CreateSessionResponseMessage] on channeID=1

Tracing a Message Send on the Server

  • Set "org.hornetq.core.client" to TRACE.
  • Look for:

The log entry regular expressions most reliably associated with handling a messages locally on the node is 

grep "send(message=ServerMessage" | grep -v "address=jms\.queue\.hornetq\.management" | grep -v "_HQ_ROUTE_TO"

_HQ_ROUTE_TO is contained by messages being routed over bridges.

Another possibility is (to be further explored): 

Routing message ServerMessage.*<queue-name>

printData

The data related to message, bindings and transaction records can be extracted using printData tool. Instructions how to run the tool can be find here:
