Database View: view_available_resources¶

This view is one of a suite of related views used by the VM scheduler to control the management of VMs. The suite includes:

The view_available_resources is used by the VM scheduler to select resources for new VMs. It presents one entry for each flavor on each cloud that is able to start one or more VMs (ie. there is enough available resources on the associated cloud to start at least one VM of that flavor) together with all the information necessary to perform the initiation.

Columns:¶

group_name (String(32)):

Is the name of the group owning the cloud.
cloud_name (String(32)):

Is the name of the cloud.

Is the filesystem path of the Certificate Authority (CA) certificate bundle used during authentication handshakes with OpenStack clouds.

Is a user specified cloud authentication parameter that allows CSV2 to manage VMs on behalf of the group.
project (String(128)):

Is a user specified cloud authentication parameter that allows CSV2 to manage VMs on behalf of the group.

Is a user specified cloud authentication parameter that allows CSV2 to manage VMs on behalf of the group.
user_domain_id (String(64)):

Is a user specified cloud authentication parameter that allows CSV2 to manage VMs on behalf of the group.
username (String(20)):

Is a user specified cloud authentication parameter that allows CSV2 to manage VMs on behalf of the group.
password (String):

Is a user specified cloud authentication parameter that allows CSV2 to manage VMs on behalf of the group.
default_flavor (String(97)):

Is the default flavor for this cloud and may be used to instantiate VMs.

Default values are only used if a specific value is not specified by the jobs requesting resources.
default_image (String(64)):

Is the default (kernel) image for this cloud and is used to instantiate VMs.

Default values are only used if a specific value is not specified by the jobs requesting resources.
default_keep_alive (Integer):

Is the default time in seconds for this cloud to keep an idle VM once it has completed a job.

Default values are only used if a specific value is not specified by the jobs requesting resources.
default_keyname (String(64)):

Is the default ssh keypair name for this cloud and may be used to instantiate VMs. During instantiation, the public key of a keypair copied to a VM allows ssh root access to the VM for diagnosis and problem resolution.

Default values are only used if a specific value is not specified by the jobs requesting resources.
default_network (String(64)):

Is the default network for VMs on this cloud and may be used when instantiating VMs.

Default values are only used if a specific value is not specified by the jobs requesting resources.
default_security_groups (String(128)):

Is the default list of security groups for VMs on this cloud and may be used when instantiating VMs. Security groups determine the firewall rules for VMs and determine which ports, sources and destinations are open for network communication.

Default values are only used if a specific value is not specified by the jobs requesting resources.
VMs (Integer):

Is the number of VMs already running this group.
VMs_max (Integer):

Is the maximum number of VMs that may be started on this resource.
cores_ctl (Integer):
cores_softmax (Integer):
cores_limit (Integer):
cores_max (Integer):

Is the maximum number cores that can currently be used on this cloud and is calculated as the least of cores control (slider) or cores soft_max minus foreign cores or the cores quota minus foreign cores.
cores_used (Integer):

Is the number of core already in use on this cloud by this group.
cores_foreign (Integer):

Is the number of core already in use on this cloud by other groups or by processes other than CSV2.
disk_used (Integer):

Is the size in gigabytes of disk already in use on this cloud by this group.
ram_ctl (Integer):
ram_max (Integer):

Is the maximum size in megabytes of RAM that can currently be used on this cloud and is calculated as the least of RAM control (slider) or the RAM quota minus foreign RAM.
ram_limit (Float):
ram_used (Integer):

Is the size in megabytes of RAM already in use on this cloud by this group.
ram_foreign (Float):

Is the size in megabytes of RAM already in use on this cloud by other groups or by processes other than CSV2.
swap_used (Integer):

Is the size in gigabytes of swap space already in use on this cloud by this group.
flavor (String(161)):

Is the name of the flavor being described.
flavor_id (String(128)):

Is the ID of the flavor being described.
flavor_slots (Integer):

Is the total number of VMs of this flavor that can be started on this resource.
flavor_cores (Integer):

Is the number of cores described by this flavor.
flavor_disk (Integer):

Is the size in gigabytes of disk described by this flavor.
flavor_ram (Integer):

Is the size in megabytes of RAM described by this flavor.
flavor_swap (Integer):

Is the size in gigabytes of swap space described by this flavor.
flavor_VMs (Integer):

Is the total number of VMs of this flavor that currently exist.
flavor_starting (Integer):

Is the number of VMs of this flavor that currently exist in the ‘starting’ state.
flavor_unregistered (Integer):

Is the number of VMs of this flavor that currently exist in the ‘unregistered’ state.
flavor_idle (Integer):

flavor_error (Integer):

Is the number of VMs of this flavor that currently exist in the ‘error’ state.
flavor_manual (Integer):

Is the number of VMs of this flavor that currently exist in the ‘manual’ state.
updater (String):

If VMs are being retired or terminated, this field will provide a string indicating which process initiated or last updated the shutdown event.
worker_cert (String):

If Grid Security Infrastructure (GSI) authentication is enabled on the group’s job scheduler, VMs started for this group will require a grid certificate (worker_cert) and key (worker_key) in order to communicate with the job scheduler. The value provided by this field is a base64, gzipped representation of the GSI authentication token and is passed to contextualization metadata templates in jinja2 variables.
worker_key (String):

If Grid Security Infrastructure (GSI) authentication is enabled on the group’s job scheduler, VMs started for this group will require a grid certificate (worker_cert) and key (worker_key) in order to communicate with the job scheduler. The value provided by this field is a base64, gzipped representation of the GSI authentication token and is passed to contextualization metadata templates in jinja2 variables.
