No, not much. Never needed much.
Anyway, I like your idea but I think this will be
critical to record and let
endusers review if their gateway is seemingly refusing RIP44 updates. These
"intermittent" refusals could be coming from their malfunctioning gateway
but more likely due to upstream equipment getting reconfigured and breaking
the end to end Protocol 4 transport for a period of time. I've seen very
similar things happening like this for DNS, SMTP, etc. but those systems all
have some level of caching, retries, etc.
In the private web directory there is a file 'deferrals' which contains
the most recent 500 of the day's 'deferred' messages extracted from the
router log every 15 minutes. Gateway operators who are curious can
download it and grep the relevant addresses out of it.
There's also a file 'gwlog.txt' containing raw data which records the
day's ICMP exceptions that the RIP sender experienced. The last two
columns are the ICMP type and code. It's really designed to be input
to a presentation program of some sort, which I haven't written yet.
Both files contain a lot of the same message over and over with just
a different timestamp. I haven't figured out a cool graphical way to
present the data.
