Schemas of Cloud Management tables

Schemas of Cloud Management tables

The tables are cloud-agnostic and so can hold data for any cloud provider.

Load balancer table

The load balancer table [cmdb_ci_cloud_load_balancer] extends from [cmdb_ci_vm_object], which extends from [cmdb_ci].

Load balancer CMDB object model
Table 1. Key native attributes of the cmdb_ci_cloud_load_balancer table
Attribute Description
object_id Identifier that typically holds the load balancer name as the value.
canonical_hosted_zone_id ID of the Amazon Route 53 hosted zone for the load balancer.
canonical_hosted_zone_name DNS name of the load balancer.
dns_name Public DNS name of the load balancer.
fqdn DNS name as fully qualified domain name. Can also be a CNAME record pointed to the DNS name.
state State of the load balancer: available or terminated.

Network resource table

The network resource table [cmdb_ci_network] extends from [cmdb_ci_vcenter_object], which extends from [cmdb_ci_vm_object], which extends from [cmdb_ci].

Network table object model
Table 2. Key native attributes of the cmdb_ci_network table
Attribute Description
object_id Identifier that typically holds the network ID as the value. Uniquely identifies an object within a cloud.
name Name of the network.
cidr IP Address range. Classless inter-domain routing is a set of internet protocol standards that is used to create unique identifiers for networks.
default_gateway Holds InternetGatewayID if we attach IntenetGateway to the network.

A default gateway serves as an access point or IP router that a networked computer uses to send information to a computer in another network or Internet. The specified gateway is used by default unless an application specifies a different gateway.

Broadcast_address

IP address used to transmit messages and data packets to network systems.

Is_shared Boolean.

true: Network shared across other projects.

false: Network not shared across other projects.

max_ports Maximum number of hosts that can be connected to the network
is_external Boolean.

true: Network is external.

false: Network is internal.

terminated_on Time that the network was de-provisioned.
state State of the network: available or terminated.
netmask Type of CIDR. 32-bit mask that divides an IP address into subnets and specify the hosts that are available on the network.
dhcp_enabled Boolean:

true: Dynamic IP address is assigned to host

false: Static IP address is assigned to host

Storage volume resource table

The storage volume resource table [cmdb_ci_storage_volume] extends from [cmdb_ci].

Storage volume resource table object model
Table 3. Key native attributes of the cmdb_ci_storage_volume table
Attribute Description
object_id Identifier that typically holds the object ID as the value. Uniquely identifies an object within a cloud.
volume_id Identifier that typically holds the volume ID as the value. Uniquely identifies an object within a cloud.
volume_container For NetApp only, LUN becomes the volume and NetApp volume becomes the volume container.
sharable Boolean.

true: Volume is shared by multiple VMs.

false: Volume is not shared by multiple VMs.

storage_type Type of storage.
  • AWS: Block
  • Azure: PageBlob
  • vSphere: VMware vdisk
size Total capacity of the volume.
free_space Available space of the volume
state State of the volume: available or in_use.
share_count Number of VMs that are shared by the volume.

Virtual server resource table

The virtual server resource table [cmdb_ci_vm_instance] extends from [cmdb_ci_vm_object], which extends from [cmdb_ci].

Virtual server table object model
Table 4. Key native attributes of the cmdb_ci_vm_instance table
Attribute Description
object_id Identifier that typically usually holds the VM instance ID. Uniquely identifies an object within a cloud.
name Name of the VM.
state State of the VML: on, off, or terminated.
cpus Number of CPUs.
memory Memory size in megabytes.
disks Number of disk drives.
disk_size Total size of disks in gigabytes.
nics Number of network interface adapters.
terminated_on Time that the instance was terminated.
termination_protection Boolean. Default value is false.

true: Can prevent the instance from being accidentally terminated using Amazon EC2.

false: Cannot prevent the instance from being accidentally terminated using Amazon EC2.
