I have a cisco asa cluster doing vpn site-to-site and remote access, but librenms does not present these information, it was important to add some information about the vpn service that are not visible in librenms like;
target, tunnel state, encryption, hashing, uptime, traffic (bandwidth)
vpn remote access
user, user group, status, amount of data, client version, remote access client type, uptime
this information would be very useful for monitoring firewalls.
