Log Rotation and Logging Options for vmware.log
Details
What configurable options are available for a virtual machine's vmware.log?
Solution
There are four options you can use to change virtual machine logging and log rotation behaviors:
logging
log.rotateSize
log.keepOld
log.fileName
logging
The logging option allows you to turn logging on or off.
- To turn logging off, enter logging="false" in the virtual machine's .vmx file.
- To turn logging back on, change logging="false" to logging="true".
log.rotateSize
By default, the virtual machine log file ( vmware.log) is rotated as a result of the virtual machine's Power On or Power Off operation.
To configure log rotation based on file size, include the following option in the .vmx file of the virtual machine:
log.rotateSize=<maximum size in bytes the file can grow to>
The following example specifies the vmware.log file to be rotated when its size reaches 100 kilobytes:
log.rotateSize=100000
log.rotateSize=<maximum size in bytes the file can grow to>
The following example specifies the vmware.log file to be rotated when its size reaches 100 kilobytes:
log.rotateSize=100000
log.keepOld
By default, ESX Server 3.0 keeps six rotations of the vmware.log file ( vmware.log, vmware-1.log, vmware-2.log... ).
To change the level of rotation, use the log.keepOld option.
The following example specifies the level of rotation to be 10:
log.keepOld=10
log.keepOld=10
log.fileName
To specify an alternative location or filename for virtual machine logging, use the log.fileName option.
The following example specifies "myVMlog" as the new file for logs instead of the default "vmware.log":
log.fileName="myVMlog"
The next example directs logs to be written to an alternate directory called "myVM" in a different VMFS volume, "vol1":
log.fileName="/vmfs/volumes/vol1/myVM/myVM.log"
