vSphere VM system log export - what's exported?

When you do a File > Export for system log,  as described in this article https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2005715 , what all is exported?

And, is this log info at all helpful if the VM is only frozen within the OS, such as an application  installed within the Windows VM that is using up all OS resources and causing to hang?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This creates a vm-support log bundle, which contains AlL the logs on the host, and also system specifications and counters handy for VMware Support.

Not really, it provides Host OS logs, VMware vSphere cannot really observe what is running on the Guest OS. You need to look at OS logs, Performance to analyse and diagnose a OS fault.

Ah ok. Guess I am a bit confused on the difference between Host system log and VM system logs?

There are individual VM logs on the host, they are called vmware.log, in the VM folder, but again these will not tell you why an application has failed in the Guest.
