In general it seems typical that VMware Tools gets installed on the Guest OS and then left alone after that. While doing some reading and working on some “slowness” issues, I’ve found the Tools CLI to become very handy and powerful.
On the Windows side of things here are a few “common” commands to use tools via the command line. First we need to get into the directory where tools is installed and the toolbox command can be run. The default directory is “C:\Program Files\VMware\VMware Tools”
The command below in the screenshot lists the base commands available with the VMwareToolboxCmd: VMwareToolboxCmd.exe help
I’m not covering all of the commands there but the documentation from VMware does a good job.
I’ve been using the VmwareToolboxCmd.exe stat “subcommandhere” for seeing stats within the GuestOS and I’ve included the snipit from the VMware doc with a little detail for each stat subcommand:
As you can see it covers many useful areas to see if the VM is having performance issues related to CPU Limits perhaps or to see if any memory is ballooning, or swapping(I’ve also included memres and cpures just to see if your VM has any reservations):
You can manually turn timesync with the host on/off/and check status:
Another command that I would imagine is useful would be the disk command and shrink subcommands that can be used to actually shrink and reduce the space the virtual disk takes up. As you can see from the screenshot my test VM is a linked clone and this can not be run against it. This doesn’t work against thick provisioned VMs as it wouldn’t shrink the virtual disk since the space has already been allocated for the virtual disk:
**NOTE certain version of Fusion have a “Clean Up Virtual Machine” button and Workstation has a “Compact” menu command that will do the same thing.
The commands are pretty much the same within a Linux OS, below is a screenshot of a CentOS VM. The default directory for this is /usr/sbin/ and the command is “vmware-toolbox-cmd”:
There are many more commands that can be run from within the Guest OS, as I stated I’ve been using and seeing these commands used to track down slowness issues within VMs.
Note these commands were taken from the following User’s Guide from VMware and VMware vSphere 6.0 Documentation Center.
