You can gather diagnostic information about the Update Manager service and the recent events on your vCenter Server system.

Because Update Manager runs as a service in the vCenter Server Appliance, the Update Manager logs are part of the vCenter Server Appliance logs. You need to collect the support bundle from the vCenter Server Appliance to view and use the Update Manager logs.

Note: In the vCenter Server Appliance, the logs that are generated during the startup of the Update Manager service are at /var/log/vmware/vmware-updatemgr/. The Update Manager runtime logs are at /var/log/vmware/vmware-updatemgr/vum-server/.


  1. Access the vCenter Server Appliance shell.
  2. Log in as a user who has the super administrator role.
    The default user with super administrator role is root.
  3. Run the vc-support command.


The vCenter Server Appliance support bundle,which includes both the Update Manager and vCenter Server logs, is a ZIP package that is located at /storage/log/.
