The discovery client 6.3.4 is available with new features and bug fixes.
The discovery client disk usage collection in Linux and Windows VMs has been enhanced for improved accuracy in disk reporting. The system now supports disk partition type discovery. For Linux VMs, discovery client reports the total disk capacity without partitioning it; for Windows VMs, the partitioned structure is reported.
ESX CPU hyperthreading detection is now supported in the collection of inventory level data from vCenter.
Reduced potential performance impact of the guest collection script on target Linux VMs by setting scripts to execute with a higher nice level.
Reduced potential performance impact of the guest collection script on target Windows VMs by optimizing the collection script.
Fixed an issue that caused Linux guest collection to report incorrect disk space in some cases by excluding network mounts and temporary file systems, and incorrectly calculating logical volumes.
Fixed an issue that caused UDP connections on Windows to not be uploaded to Migration Center.
Fixed an issue that caused VMs with a very large number of running processes, services, installed applications, or open files handlers, to be reported incorrectly to Migration Center.

The Migration Center discovery client CLI (mcdc CLI) supports the offline assessment of migrating VMs running on VMWare vSphere to VMs running on Google Distributed Cloud (GDC) air-gapped.
The mcdc CLI now assesses the migration fit of VMware VMs to Google Distributed Cloud air-gapped with a journey called "Shift | Google Distributed Cloud". This journey is available in all report formats by default. To generate a report focused on applicable journeys to GDC including existing containerization journeys, run the following command using the mcdc CLI for Linux or Windows:
./mcdc report --format FORMAT --target-platform gdc --file REPORT_NAME
For more information, see Offline assessment rules.
The following are open known issues with the Migration Center discovery client 6.2.0:
- The maximum number of scanned servers is limited to a total of 2,000 servers. Exceeding this limit may cause instability.
- Opting out from analytics and Cloud Logging can only be done from the Settings page of the discovery client application.
- In some cases, the discovery client service might not run after boot, and users would get a "connection refused" error when opening the discovery client application. A workaround is to configure the discovery client service to have a delayed start.
