Zerto Virtual Replication Reports : Resources Report : Details Tab
  
Details Tab
The Details tab includes the names and IDs of the virtual machines being protected and, for each virtual machine, the timestamp for the information, where it is protected, the CPU used, the memory used by the host and the guest, the storage used, and other information.
Interpreting the Details Tab
The Details tab provides a breakdown of every protected virtual machine, identified by its internal identifier and name in the hypervisor manager. The report also includes the name of the VPG that is protecting the virtual machine and information such as the protected and recovery sites, the protected and recovery vCD Org, cluster, etc.
The Timestamp column displays the time when the last sample, as defined in the Reports tab of the Site Settings dialog, was taken.
The VPG Type column is one of:
VC2VC – vCenter to vCenter replication
VC2VCD – vCenter to vCloud Director replication
VCD2VCD – vCloud Director to vCloud Director replication
VCD2VC – vCloud Director to vCenter replication
The ZORG column defines organizations set up in the Zerto Cloud Manager that use a cloud service provider for recovery.
The Bandwidth (Bps) and Throughput (Bps) columns display the average between two consecutive samples. With daily samples, these figures represent the average daily bandwidth and throughput. For hourly samples, the timestamp represents an average between the sample at the timestamp and the previous sample. A value of -1 means that the system failed to calculate the value, which can happen for several reasons, for example:
Sites were disconnected when the sample was collected. Although the protected site measures the throughput and bandwidth, the recovery site logs the results.
The bandwidth or throughput values at the time of the sample was lower than the bandwidth or throughput value in the previous sample. This can happen, for example, if the protected site VRA is rebooted since the sample values are not stored persistently by the VRA.
If valueInLastSample does not exist, since currentValue is the first sample for the virtual machine, the data is not calculated.
Bandwidth is calculated as: (currentValue – valueInLastSample)/elapsedTtime
For example:
Time
Action/Description
2:29:59.999
A virtual machine is placed in a VPG
2:30
A sample is generated. The total transmitted bytes is zero since the virtual machine was just placed in the VPG
2:30-2:59.999
The VM is writing data at 1MB/minute
3:00
The virtual machine lowers its write rate to 0.5MB/minute
3:30
A new sample is calculated. Current value of total data transmitted is 45MB:
1MB/minute)*(30 minutes) + (0.5MB/minute)*(30 minutes)
Last value of total data transmitted is 0, from the 2:30 sample.
Bandwidth = (45MB-0)/(60 minutes) = 0.75MB/minute = 13107Bps
Report output fields
The following describes the fields in the Details tab.
Parameter
Description
Active Guest Memory (MB)
The active memory of the virtual machine.
Bandwidth (Bps)
The average bandwidth used between two consecutive samples, in bytes per second.
Consumed Host Memory (MB)
The amount of host memory consumed by the virtual machine.
CPU Limit (MHz)
The maximum MHz available for the CPUs in the virtual machine.
CPU Reserved (MHz)
The MHz reserved for use by the CPUs in the virtual machine.
CPU Used (MHz)
The MHz used by the CPUs in the virtual machine.
CrmId
The CRM identifier specified in Zerto Cloud Manager for an organization that uses a cloud service provider for recovery.
Memory (MB)
The virtual machine defined memory.
Memory Limit (MB)
The upper limit for this virtual machine’s memory allocation.
Memory Reserved (MB)
The guaranteed memory allocation for this virtual machine.
Number Of vCPUs
The number of CPUs for the virtual machine.
Number Of Volumes
The number of volumes attached to the virtual machine.
Recovery Journal Provisioned Storage (GB)
The amount of provisioned journal storage for the virtual machine. The provisioned journal size reported can fluctuate considerably when new volumes are added or removed.
Recovery Journal Used Storage (GB)
The amount of journal storage used by the virtual machine.
Differences might occur between the value displayed in the Used Journal column in the Protection Over Time by Site report and the value displayed here, which is retrieved from vCenter or Hyper-V.
The Used Journal value displayed in the Protection Over Time by Site report is calculated by the VRA, based on internal journal allocations for each recovery volume.
vCenter and Hyper-V Resources reports are expected to display a larger size than in the Protection Over Time by Site report, and may reach up to 500MB higher per virtual machine than reported in the Protection Over Time by Site report.
Recovery Volumes Provisioned Storage (GB)
The amount of provisioned storage for the virtual machine in the target site. This value is the sum of volumes’ provisioned size.
Recovery Volumes Used Storage (GB)
The amount of storage used by the virtual machine in the target site.
Service Profile
The service profile used by the VPG.
Source Cluster
The source cluster name hosting the virtual machine.
Source Host
The source host name hosting the virtual machine.
Source Organization VDC
The name of the source vDC organization.
Source Resource Pool
The source resource pool name hosting the virtual machine.
Source Site
The source protected site name, defined in the Zerto User Interface.
Source vCD Organization
The name of the source vCD organization.
Source Volumes Provisioned Storage (GB)
The amount of provisioned storage for the virtual machine in the source site. This value is the sum of volumes’ provisioned size.
Source Volumes Used Storage (GB)
The amount of storage used by the virtual machine in the source site. This value is the sum of the volumes’ used size.
Source VRA Name
The name of the source VRA used to send data to the recovery site.
Target Cluster
The target cluster name hosting the virtual machine.
Target Datastores
The target storage used by the virtual machine if it is recovered.
Target Host
The target host name hosting the virtual machine when it is recovered.
Target Organization vDC
The name of the target vDC organization.
Target Resource Pool
The target resource pool name where the virtual machine will be recovered.
Target Site
The target site name, defined in the Zerto User Interface.
Target Storage Policy
The target vCD storage policy used.
Target vCD Organization
The name of the target vCD organization.
Target VRA Name
The name of the VRA managing the recovery.
Throughput (Bps)
The average throughput of the VM used between two consecutive samples, in bytes per second.
Timestamp
The date and time the resource information was collected. The value can be converted to an understandable date using code similar to the following:
var date = new Date(jsonDate);
or code similar to the Perl code example, jsonDateToString($), described in Zerto Virtual Replication RESTful API Reference Guide.
VM Hardware Version
The VMware hardware version.
VM Id
The internal virtual machine identifier.
VM Name
The name of the virtual machine.
VPG Name
The name of the VPG.
VPG Type
The VPG type:

VCvApp – Deprecated
VCDvApp – VMware vCloud Director vApp
PublicCloud – Amazon WebServices or Microsoft Azure
HyperV – Microsoft SCVMM
ZORG
The name assigned to an organization using a cloud service provider for recovery. The name is created in the Zerto Cloud Manager. For details, see the Zerto Cloud Manager Administration Guide.
