Logging state of interface

I am just wondering if there is a possbility to log the state of an interface, e.g. logging the state of the external interface e.g. logging when it goes down and/or up? Background ist to check the state of a ceretain interface at a specifique time.

I did not find any loggings about this?

Is this possbile and where can I find the logs?

    You will see entries in Traffic Monitor when an interface goes down or comes back up.

    networkd [eth0 (External)] Interface link status changed to up msg_id="3100-002C"

    If you have Link Monitor set up, you will see this:
    [Link Monitor] No response received on External from Ping target

    It's worth adding that the firebox won't be able to log an interface going down if the log server that its communicating to is only reachable over that interface.

    E.g., if your log server is external to your firewall, and your ISP connection goes down, any logs sent during that time will be lost.
