--------------------------------
Summary: Expose excessive resource utilisation through management
Key: QPID-7687
URL: https://issues.apache.org/jira/browse/QPID-7687
Project: Qpid
Issue Type: Improvement
Components: Java Broker
Reporter: Keith Wall
For multi tenant use-cases it is important for an operator managing a Broker to
be able to identify an errant application. For example, if an application is
creating excessive connections, the operator need a mechanism to identify the
endpoint and connection details so intervention can be taken to protect the
service.
The model statistics currently don't expose this information. Useful
information can be gleaned from the logs, but this is inconvenient if the logs
have rolled and often needs a bit of tricky awking to pull out the relevant
information.
* Authentication Provider could keep a tally of authentications per user id
* Port a tally of number of opened connections per endpoint. The tallies
would use LFU cache.
* Excessive messaging Sessions is also a common anti-pattern. Connections
should have a statistic counting the number of Sessions created on them.
The information would be exposed through the REST API/Web Management Console.
A summary could also be periodically written to the log by the housekeeper.
Configurable alerting rules would report if the number of
connections/session/consumers opened within a time period is deemed too high.
