XML Output Example
hypervisor – an array of all compute resources in the cloud and their details
backup - true, if the CloudBoot compute resource is used as a backup server. This parameter is for CloudBoot compute resources only. For other compute resource types the backup value is 0.
backup_ip_address - provisioning network IP address
blocked - true if the compute resource is blocked, otherwise false
built - true if the compute resource is built, otherwise false
called_in_at – the date when the compute resource was called in the [YYYY][MM][DD]T[hh][mm][ss]Z format
connection_options - an array of the following vCenter cluster parameters:
- login - vCenter login
- password - vCenter password
- cluster_name - vCenter cluster name
- distributed_virtual_switch_name - distributed virtual switch label
cpu_idle - time of CPU delay
cpu_mhz - CPU operating frequency
created_at – the date in the [YYYY][MM][DD]T[hh][mm][ss]Z format
custom_config - custom commands that run when the compute resource is booted
disable_failover – true if compute resource failover is disabled, otherwise false.
disk_pcis - comma-separated list of hypervisor disk pcis
distro - distributive label
enabled - true, if the compute resource is enabled, otherwise false
failure_count – the number of failures
format_disks - true, if the compute resource's disks are formatted during creation, otherwise false
free_mem - free compute resource memory
host - host label
hypervisor_group_id - the ID of a compute zone to which this compute resource is attached
hypervisor_type - the compute resource type
id - the compute resource ID
ip_address – the compute resource IP address
label - the compute resource label
list_of_logical_volumes - an array of compute resource logical volumes
list_of_volume_groups - an array of compute resource volume groups
list_of_zombie_domains - an array of zombie virtual servers
locked - true if the compute resource is locked, otherwise false
mac - compute resource MAC address
machine - architecture type
mem_info - Xen compute resource Dom0 size. This parameter is for Xen compute resources only. For other compute resource types the mem_info value is 0.
mtu - maximum transferrable unit value. You can set the frame size from 1500 to 9000 bytes.
The maximum transportation unit (MTU) is the maximum size of a unit that can be transmitted transferred via ethernet traffic. Any data that exceed the specified MTU value will be divided into smaller units before being transferred. Utilization of jumbo frames allows to reduce increase throughput and increase CPU utilization during large size file transfers.
online - true if online, otherwise false
ovs - whether the OpenvSwitch is enabled or not. Redundant parameter.
passthrough_disks - true, if the disks are passed through to the storage nodes, otherwise 0
release - compute resource kernel version
segregation_os_type - an operating system type (can be Any OS, Windows only or Non-Windows)
server_type - server type:
spare – true if no VSs are assigned, otherwise false
storage_channel - storage channel for the communication
threads_per_core - compute resource core and CPU ratio. For example, if threads_per_core = 2, compute resource with 2 cores will have 4 CPUs.
total_mem - total compute resource memory
total_zombie_mem - memory space occupied by zombie disks
updated_at – the date when the record was made in the DB in the [YYYY][MM][DD]T[hh][mm][ss]Z format
uptime - compute resource uptime value; shows how long the compute resource is online
vmware_total_cpu_cores - the total number of VMware compute resource CPU cores
total_cpus – the number of virtual cores
free_memory – free RAM (MB) of compute resource. It is calculated as follows: total memory - memory overhead* - zombie VSs - sum of all VSs
used_cpu_resources – the percentage of used CPU resources
total_memory – total RAM (MB) of compute resource
cpu_cores – the number of physical cores per compute resource
free_disk_space - free compute resource disk space in GB
memory_allocated_by_running_vms - the compute resource RAM in MB allocated to the virtual servers, which are currently running on this compute resource
total_memory_allocated_by_vms - the compute resource RAM in MB allocated to all virtual servers of this compute resource
cpu_units - the amount of CPU units assigned to this compute resource
cpu_flags - an array of CPU flags of the compute resource for which the extended CPU configuration is enabled
cpu_model - a CPU model of the compute resource for which the extended CPU configuration (flags) is enabled
*Memory Overhead for Compute Resources
Each compute resource has a reserved memory overhead value. This value is pre-configured by default in info_hub.yml.
For XEN compute resource:
memory_overhead = 1536
For KVM compute resource:
memory_overhead = 400 + 0,024 * total_memory
Added the following parameters:
Added the cpu_model parameter.
