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
