OpenStack data source

The OpenStack (REST API / KVM) data source collects information about OpenStack hardware instances. This data source collects inventory data for all OpenStack instances, and optionally, VM performance data.

Requirements

The following are requirements for configuring the OpenStack data source.

  • IP address of the OpenStack controller
  • OpenStack admin role credentials and sudo access to the Linux KVM hypervisor.
    Note: If you are not using the admin account or admin equivalent privileges, you need to use trial and error to identify the default policies to relax for your data source userid.
  • For performance collection the OpenStack Ceilometer module must be installed and configured. Configuring the Ceilometer is done by editing the nova.conf file for each hypervisor and then restart the Nova Compute service on each hypervisor. The option name changes for different releases of OpenStack:
    • Icehouse
    • Juno
    • Kilo
    • Liberty
    • Mitaka
    • Newton
    • Ocata
  • For CPU stats, "compute_monitors=ComputeDriverCPUMonitor" needs to be turned on in /etc/nova/nova.conf on compute nodes.
  • Port requirements:
    • 5000 for http and 13000 for https, for the Keystone service
    • 22 for KVM SSH
    • 8774 for Nova Compute Service
    • 8776 for Cinder Block Service
    • 8777 for Ceilometer Performance Service
    • 9292 for Glance Image Service
      Note: The port binds to the specific service, and the service may run on the controller or another host in larger environments.
