7.2. Change Broker Logging Verbosity
- Changes
- New content - added February 2013.
When running qpidd from command line, use
--log-enable option with the syntax:
--log-enable LEVEL[+][:PATTERN]
When using a configuration file (
/etc/qpid/qpidd.conf by default), use the line:
log-enable=LEVEL[+][:PATTERN]
Notes
LEVELis one of:trace debug info notice warning error critical.- The "
+" means log the given severity and any higher severity (without the plus, logging of the given severity only will be enabled). PATTERNis the scope of the logging change.- The string in
PATTERNis matched against the fully-qualified name of the C++ function with the logging statement. - To see the fully-qualified name of the C++ function with the logging statement, either check the source code or add to the qpid configuration the
log-function=yesoption to force qpid broker to log such message. - So e.g.
--log-enable debug+:hamatches everything in theqpid::hamodule, while e.g.--log-enable debug+:broker::Queue::consumeNextMessagewill enable logging of one particular method only (theconsumeNextMessagemethod in the given namespace in this example). PATTERNis often set to the module one needs to debug, likeacl,amqp_0_10,broker,ha,managementorstore.- The option can be used multiple times.
- Be aware that having just one option like "
log-enable=debug+:ha" enables debug logs of ha information, but does not produce any other logs; to add some more verbose logging, add an option like the above and also add the default value:log-enable=info+
