Find the "log.rotateSize" value and set it to "2048000".

Note: The VM must be powered off to modify the advanced settings through the vSphere Client. It is recommended to configure these settings with PowerCLI as this can be done while the VM is powered on. In this case, the modified settings will not take effect until a cold boot of the VM.

or

From a PowerCLI command prompt while connected to the ESXi host or vCenter server, run the provided commands as shown below.
