Supply the following if possible:
openwrt 21.02.1 on x86_64 (virtualbox) interfaces are all Intel Pro/1000 T Server 82543GC logread is configured to forward messages to a syslog server
It seems as if logread forwarding starts before it is able to actually send messages to the syslog server, resulting in lost messages. This is important as the syslog server generates monitoring information, including status of all interfaces on the router. The loss of early interface messages means that the monitoring does not get a full picture of the status of these devices.
I have attached a log of the console output from the router bootup. I have also attached a log of the messages received by the syslog server.
Interestingly, other routers forward their messages to the same syslog server and yet none of those routers' messages are dropped. These routers have nearly identical configuations too.
Incidentally, a google search reveals that this was previously logged on the old openwrt bug tracker at [[https://dev.archive.openwrt.org/ticket/13861.html|External Link]]. Additionally, a similar bug was logged against logread at [[https://github.com/josefbacik/busybox/issues/4.|External Link]].
