Re: Can I expose Java properties set in the Qpid broker server via JMX or the REST API?
I dont know about the more general question (but I see Alex answered before I finished this), though on this item specifically... What you are asking about is from an MBean created by the JVM within its Platform MBeanServer, so the broker itself actually has nothing to do with it. If you fired up two instances of JConsole and connected one to the other you would see the same MBean listed.

Re: Can I expose Java properties set in the Qpid broker server via JMX or the REST API?
Hi Brian, You can add a suffix to the Apache Qpid version which is exposed via Broker attribute 'productVersion'. For example, if version of Qpid Broker is 7.0.6 and suffix is set to 'MY-CORP-1.3', the product version would be '7.0.6;MY-CORP-1.3'. This can be achieved by adding into broker lib folder (classpath) a jar with a file 'qpid-common.properties' containing property 'qpid.version.suffix'. For example, qpid.version.suffix=MY-CORP-1.3 Thus, with every internal broker release/build you can generate qpid-common.properties with your company version which would ne available via prefix of productVersion attribute. This approach is used in a company I am working for. Alternatively, you can try to create a context variable with a value set to your company version. The context variable can be set as environment property, JVM system property, specified in file 'system.properties' available in classpath, set as command line argument (for example, '-prop my.company.version=1.2.3' ) or set in initial configuration broker context attribute. However, the context variables can be modified/overridden via REST API and can be mistakenly changed when broker is running which makes this approach unreliable. By default, the context variable not set directly on the configured object (for instance, the ones injected via JVM system properties including variables specified in file 'system.properties' ) are not returned in REST API responses. In order to see them, you need to call REST API with a parameter 'excludeInheritedContext=false'. (For example, https://localhost:8443/api/v7.0/broker?excludeInheritedContext=false) Kind Regards, Alex On Wed, 19 Dec 2018 at 22:18, Brian O'Shea wrote: > > Looking at jconsole (connected to the running Qpid broker), it appears that > it exposes a Map under java.lang -> Runtime -> Attributes -> > SystemProperties.

Re: Can I expose Java properties set in the Qpid broker server via JMX or the REST API?
Looking at jconsole (connected to the running Qpid broker), it appears that it exposes a Map under java.lang -> Runtime -> Attributes -> SystemProperties. Is this something that I can depend on always being available? This is Qpid version 7.0.6, which no longer supports management over JMX, but will this attribute always be accessible over JMX?

Can I expose Java properties set in the Qpid broker server via JMX or the REST API?
Hello Qpid maintainers, My organization uses Qpid, and we occasionally deploy configuration changes that we track using a build number that we generate internally. We would like to find a way to expose this build number so that our application can access it to see what "build" the Qpid broker is (this is not the Qpid version number, and only has meaning to our organization). Ideally we would access it via the REST API, but I realize that this might not be feasible. Can you think of a way that I can store this build number in the broker somehow that can be accessed remotely? Thanks. Let me know if you need clarification.
