  • Component services user, changed date, expiry date, expiry in days, etc.

Collecting Log Files

  • Logs are collected for all components within a specific domain.
  • For specific components, use options like --api-logs
  • Use the command sudo /opt/vmware/sddc-support/sos -domain-name MGMT for collecting all logs from MGMT domain.

VCF Services and Log Files

  • Open a SR (Service Request) for best practices.
  • Open SRs with VCF product Name.
  • Begin collecting logs before opening a ticket.
  • Use the relevant component.
  • Reboot SDDC Manager.

Key Log Files

  • sddcmanager_restart_services.sh script.

  • Systemctl to restart individual services.

  • /var/log/vmware/vcf/ folder in SDDC Manager

  • /commonsvcs

  • /domainmanager

  • Expand the workflow tasks in SDDC manager and identify failed subtasks.
