Message Queues for LHCb

The IT Message Queue service has setup two ActiveMQ brokers for us, configured the same way: lhcb-test-mb and lhcb-mb.

Queues and topics

This is the destinations that we are allowed:

/queue/lhcb.certification
/queue/lhcb.dirac.{path}
/queue/lhcb.jenkins
/queue/lhcb.test.{name}
/topic/lhcb.dirac.{path}

where {path} can be anything and {name} any word without dots.

Authentication & Authorizations

Authentication can be done via user name, or via host DN.

For convenience, we use a dirac user for every interaction. The IT guys have a list of our machines, but we have to ask them to update it every time we add a machine, so it is not very convenient.

Monitoring

We can see how are our queues doing on this monitoring link

cluster can be either lhcb or lhcb-test
