Service checks

  • openstack_check_api, the service's API status, 1 if it is responsive,

    if not, then 0. The metric contains a service field that 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.
  • openstack_nova_instance_state, the number of instances which entered a given state (the value is always 1). The metric contains a state field.
  • openstack_nova_running_instances, the number of running instances.
  • openstack_nova_running_tasks, the number of tasks currently executed.
  • openstack_nova_used_disk, the disk space in GB used by the instances.
  • openstack_nova_used_ram, the memory in MB used by the instances.
  • openstack_nova_used_vcpus, the number of virtual CPU used by the instances.

The following metrics are retrieved from the Nova API and represent the aggregated values across all compute nodes.

  • openstack_nova_total_free_disk, the total amount of disk space in GB available for new instances.
  • openstack_nova_total_free_ram, the total amount of memory in MB available for new instances.
  • openstack_nova_total_free_vcpus, the total number of virtual CPU available for new instances.
  • openstack_nova_total_running_instances, the total number of running instances.
  • openstack_nova_total_running_tasks, the total number of tasks currently executed.
  • openstack_nova_total_used_disk, the total amount of disk space in GB used by the instances.
  • openstack_nova_total_used_ram, the total amount of memory in MB used by the instances.
  • openstack_nova_total_used_vcpus, the total number of virtual CPU used by the instances.

The following metrics are retrieved from the Nova API:

  • openstack_nova_instances, the total count of instances in a given state. The metric contains a state field which is one of 'active', 'deleted', 'error', 'paused', 'resumed', 'rescued', 'resized', 'shelved_offloaded' or 'suspended'.
  • openstack_nova_service, the Nova service state (either 0 for 'up', 1 for 'down' or 2 for 'disabled'). The metric contains a service field (one of 'compute', 'conductor', 'scheduler', 'cert' or 'consoleauth') and a state field (one of 'up', 'down' or 'disabled').
  • openstack_nova_services, the total count of Nova services by state. The metric contains a service field (one of 'compute', 'conductor', 'scheduler', 'cert' or 'consoleauth') and a state field (one of 'up', 'down', or 'disabled').

Identity

The following metrics are retrieved from the Keystone API:

  • openstack_keystone_roles, the total number of roles.
  • openstack_keystone_tenants, the number of tenants by state. The metric contains a state field (either 'enabled' or 'disabled').
  • openstack_keystone_users, the number of users by state. The metric contains a state field (either 'enabled' or 'disabled').

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.

Note

When using Ceph as the back end storage for volumes, the hostname value is always set to rbd.

The following metrics are retrieved from the Cinder API:

  • openstack_cinder_snapshots, the number of snapshots by state. The metric contains a state field.
  • openstack_cinder_snapshots_size, the total size (in bytes) of snapshots by state. The metric contains a state field.
  • openstack_cinder_volumes, the number of volumes by state. The metric contains a state field.
  • openstack_cinder_volumes_size, the total size (in bytes) of volumes by state. The metric contains a state field.

state is one of 'available', 'creating', 'attaching', 'in-use', 'deleting', 'backing-up', 'restoring-backup', 'error', 'error_deleting', 'error_restoring', 'error_extending'.

  • openstack_cinder_service, the Cinder service state (either 0 for 'up', 1 for 'down', or 2 for 'disabled'). The metric contains a service field (one of 'volume', 'backup', 'scheduler') and a state field (one of 'up', 'down' or 'disabled').
  • openstack_cinder_services, the total count of Cinder services by state. The metric contains a service field (one of 'volume', 'backup', 'scheduler') and a state field (one of 'up', 'down' or 'disabled').

Image

The following metrics are retrieved from the Glance API:

  • openstack_glance_images, the number of images by state and visibility. The metric contains state and visibility fields.
  • openstack_glance_images_size, the total size (in bytes) of images by state and visibility. The metric contains state and visibility fields.
  • openstack_glance_snapshots, the number of snapshot images by state and visibility. The metric contains state and visibility fields.
  • openstack_glance_snapshots_size, the total size (in bytes) of snapshots by state and visibility. The metric contains state and visibility fields.

state is one of 'queued', 'saving', 'active', 'killed', 'deleted', 'pending_delete'. visibility is either 'public' or 'private'.
