Site-to-site VPN tunnel logs

[Gacki]

Hello,
I would like to know how to check the log history in the console for a given VPN site to site.

We have a VPN site to site set up with another company, and there was a case that the VPN tunnel was broken for an hour, you can't see anything in the SMS logs, there is only an hour hole, the question is whether it is possible in the console to download logs from a given tunnel at a given time deeper hour.
Thank you very much for help

The sms version is R81.10
Firewall - r81.10

Logs at least should show why the tunnel went down and later up again ! If VPN is down it will not log.
