The Server Manager:

  • Monitors the KVM hypervisor and virtual machine status by periodically polling the NOVA API in OpenStack.

  • Generates notifications when:

    • A hypervisor is down.

    • A virtual machine is down or has been turned off.

  • Monitors the Rabbit MQ (RMQ) status by the subscription mechanism or by using SNMP to monitor the RMQ process.

  • Generates a Down notification when the service subscription is broken or the RMQ service stops.
