Wan error log


Today one of my ISP's wan line showed me an error status then came back up a few times, called my ISP and it was their problem and they fixed.  But I'm still searching all the instance of when this happened.  What log file shows the error states log of a wan connection?

  • Service Monitor logs from the “Logging ->  View Log Files" menu or the command line (less /var/log/service_monitor.log).

    From documentation:
    The UTM checks the WAN links using ICMP messages. Not only the Default Gateway is checked, as a Traceroute is sent to the Root DNS Server. A host is selected along the path to the root server, and the accessibility of this host is checked permanently by way of a ping.
