======================= 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`
