To view the current status during migration of a VM running in Google Cloud:
- In the vSphere Navigator panel, select the VM you want to review.
- Click the Summary tab.
- In the Summary screen, click the Cloud Instance Information portlet.
This portlet includes the following information:
- Which Cloud Extension node the VM is using
- IP addresses
- Storage policy
- The Google Cloud Service Account that owns the VM
- VM properties such as:
- CPUs
- RAM
- Zone
- Accessibility to the Remote Console
When the Remote Console status is Ready, the Velostrata Backend can access the instance via either RDP (port 3389 over TCP) for Windows VMs or SSH (port 22 over TCP) for Linux VMs.
Viewing historical instance performance
Historical performance and operational statistics are available individual VMs under the Monitoring > Velostrata Cloud Instance tab.
You can view the following metrics at the instance level:
- Workload:
- VM Workload IOPS: Storage I/O operations that the VM used on the Cloud Extenstion.
- Workload - IO Latency (ms): Average storage I/O operation latency. Measured at one-minute intervals.
- Workload (Bytes/sec): Network throughput for the VM.
- Uncommitted Writes (Bytes): The difference in write data buffered for writing back on-premises. If writeback is disabled, the number of uncommitted writes increases as the instance writes more data to disk. If writeback is enabled, the number of uncommitted writes is reduced after each writeback.
- vSphere Datastore:
- vSphere Datastore IOPS: Input/Output operations written to the vSphere datastore for this VM.
- vSphere Datastore Bytes (cumulative): Total bytes read from on-premises or written to this VM. The graph's slope identifies the amount of data change per time.
- vSphere Datastore Bytes (Bytes/sec): Total throughput of vSphere datastore storage access driven by the VM's activity on Google Cloud.
- IO Offload %: The ratio between I/O operations handled from the cache on Google Cloud vs I/O operations on the vSphere datastore on prem.
- Change set Compaction Ratio %: Compression efficiency in the data written back on-premises.
- VM Exporter: The remaining number of records to be synchronized to Google Cloud. This is indicative of data throughput, allowing you to estimate how long until the VM reaches the Ready to Detach state.
