  2. Scroll down to the "Nodes" section
  3. There should be 3 rows in the table and all status icons should be green (currently - there is a red bar showing a deprecated node - this will be removed when possible).  The expected node hostnames are:
    • prod-noc-alarms01.geant.org
    • prod-noc-alarms02.geant.org
    • prod-dashboardnoc-storage01alarms03.geant.org
Solution
  1. If one of the 3 nodes is failing or missing from the list, log into the failing server via ssh and restart the RabbitMQ service:
    • sudo systemctl restart rabbitmq-server
  2. After a minute or two the management consoles should show the cluster is restored.
