Description |
Measurement Unit |
Interpretation |
| Status |
Indicates the current status of this data center.
|
|
This measure reports the status of the datacenter and their numeric equivalents as shown in the table:
| Numeric Value |
Measure Value |
| 0 |
Not Operational |
| 1 |
Up |
| 2 |
Uninitialized |
| 3 |
Maintenance |
| 4 |
Problematic |
| 5 |
Contend |
Note:By default, this measure reports one of the Measure Values listed in the table above. The graph of this measure however will represent status using the numeric equivalents - ‘0 to 5’.
|
| Num_sto_dmn |
Indicates the current number of storage domains that are available in this datacenter.
|
Number |
Use the detailed diagnosis of this measure to know which storage domains are part of the data center. |
| Total_space |
Indicates the total disk capacity of this datacenter.
|
GB |
|
| Free_space |
Indicates the total unused space in this datacenter.
|
GB |
A high value is desired for this measure. |
| Used_space |
Indicates the amount of disk space that is currently utilized in this datacenter.
|
GB |
Ideally, the value of this measure should be low. |
| Pct_free |
Indicates the percentage of disk space that is currently free in this datacenter.
|
Percent |
A low value or a steady decrease in the value of this measure indicates the gradual erosion of disk space from the hosts in the data center. If the situation persists, then the data center may suddenly run very low on disk space, causing the hosts and VMs in the data center to fight over the meager resources. This in turn will affect the performance of the VMs, hosts, and the applications executing on the VMs. |
| Num_hosts |
Indicates the current number of RHEV servers in this data center.
|
Number |
Use the detailed diagnosis of this measure to know which RHEV servers are part of the data center. |
| Num_vms |
Indicates the current number of VMs in this data center.
|
Number |
Use the detailed diagnosis of this measure to know which virtual machines are part of the data center. |
| Num_cluster |
Indicates the number of clusters in this datacenter.
|
Number |
Use the detailed diagnosis of this measure to know which clusters are part of the data center. |
| Version |
Indicates the compatibility level of this data center.
|
Number |
Each host connected to Red Hat Enterprise Virtualization Manager contains a version of VDSM. VDSM is the agent within the virtualization infrastructure that runs on a hypervisor or host and provides local management for virtual machines, networks and storage. Red Hat Enterprise Virtualization Manager controls hypervisors and hosts using current or older versions of VDSM. The Manager migrates virtual machines from host to host within a cluster. This means the Manager excludes certain features from a current version of VDSM until all hosts within a cluster have the same VDSM version, or more recent, installed.
The API represents this concept as a compatibility level for each host, corresponding to the version of VDSM installed. A version element contains major and minor attributes, which describe the compatibility level. When an administrator upgrades all hosts within a cluster to a certain level, the version level appears under a supported_versions element. This indicates the cluster's version is now updatable to that level. Once the administrator updates all clusters within a data center to a given level, the data center is updatable to that level.

| Supported_ver |
Indicates the supported version of this data center.
