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.

How much the below highlighted statement
is true ? How can I get the list of features/advantages that wireshark provides
?
Thanks for the reply in advance.
Hi,
We are installing this software
on request of XXXX network team because they want to make sure that the VPN
itself is getting disconnected or not, which as per our observation is not
getting disconnected. The sniffer software is
not going to tell anything more, it will not be able to provide application
traffic information (because it will be encrypted). So we do not think that is required in this case, which
I told clearly in the call as well, so it is basically to satisfy them, because
they are not seeing your desktop which we can. I hope this clears your doubt.
