Service API checks

  • openstack_check_api, the service's API status through the load balancer

    VIP, 1 if it is responsive, if not, then 0. The metric contains a service field that identifies the OpenStack service being checked.

  • openstack_check_local_api, the service's API status checked locally. 1 if it is responsive, if not, then 0. The metric contains a service field that identifies <service> identifies the OpenStack service being checked.

<service> is one of the following values with their respective resource checks:

  • 'ceilometer-api': '/v2/capabilities'
  • 'cinder-api': '/'
  • 'cinder-v2-api': '/'
  • 'glance-api': '/'
  • 'heat-api': '/'
  • 'heat-cfn-api': '/'
  • 'keystone-public-api': '/'
  • 'neutron-api': '/'
  • 'nova-api': '/'
  • 'swift-api': '/healthcheck'
  • 'swift-s3-api': '/healthcheck'

Note

All checks except for Ceilometer are performed without authentication.

Compute

The following metrics are emitted per compute node:

  • openstack_nova_free_disk, the disk space in GB available for new instances.
  • openstack_nova_free_ram, the memory in MB available for new instances.
  • openstack_nova_free_vcpus, the number of virtual CPU available for new instances.
  • openstack_nova_instance_creation_time, the time in seconds it took to launch a new instance.

Volume

The following metrics are emitted per volume node:

  • openstack_cinder_volume_attachement_time, the time in seconds it took to attach a volume to an instance.
  • openstack_cinder_volume_creation_time, the time in seconds it took to create a new volume.
