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.
