Virtual Machine Log Files

Each running virtual machine has its own log file,
vmware.log
, stored on the VMFS volume. By default, the log file is rotated whenever the virtual machine is powered on, but file rotation is configurable.
  • ESXi maintains six log files that rotate at each power-cycle (the default) or at a configured file size.
  • ESXi can be configured to maintain a specific number of log files. When the limit is reached, the oldest file is deleted.
  • VMware recommends a log file size of 500 KB.
  • Messages that are generated by VMware Tools are logged separately.
