Wireshark is simply an intelligent microscope for your network. Not only
does it show show details (packets and bytes), it also labels many of the
features for you. It can decode a lot of protocols and even some encrypted
protocols, like SSL or WEP (provided you have the keys).

It might well be that you won't be able to decrypt the VPN traffic in
wireshark. However I expect you might be able to tell a lot from things like
setup and teaddown sequences (for instance ISAKMP) which do have a lot of
"plain-text" information. Also if the protocols runs over TCP you might see
retransmissions that are say caused by firewall or congestion issues.

Like a microscope in the hands of a biologist, what you see still requires
interpretation. Hopefully Wireshark might help you do that.
