Hi Team,I would like to ask if we can trigger an alert with the Site-to-Site VPN Tunnel monitoring feature that we have with Advance ASA monitoring
Yes, There is an out-of-box alert called VPN Site-to-Site tunnel down.
(Orion Menu) Alerts & Activity / Alerts / Manage Alerts (search for VPN)
You can "duplicate & Edit" this to meet your needs.
Hope this helps
