Generate alarms on packet loss/gateway change and log them

[mgiammarco]

Hi,
I have some OPNsense with dual wan and I need to check quality of internet connections.
Obviously OPNsense change gateway automatically on packet loss or line down.
I need to receive an alarm when a line goes down or there is packet loss.
I would like also to have a centralized log for problems.
I am trying several monitoring solutions but all focus on monitoring cpu/mem usage or ethernet traffic and no one focus on gateway data.
Have you some suggestions?
Thanks,
Mario
