Overload data for Exit vs Non-Exit (and Guard vs Middle)?

To try to get to the bottom of the recent influx of clients to the Tor network, it might be useful to compare load characteristics since 8/19 for nodes with different types of flags. People with Munin setups: it would be especially useful if you could post links/graph images for connection counts, bandwidth, and CPU load since 8/19. I'm particularly interested if people with just the Exit flag (w/o Guard) are seeing increased connection counts that aren't explained by uptime or ramp-up. So far the only datapoint I have for this is https://www.torservers.net/munin/torservers.net/psilotorlu.torservers.net/in... but it looks like that node just rebooted and possibly rekeyed, so it's connection increase could just be due to that. It would also be interesting to see if Guard+Exits are seeing a greater increase in connection counts than just Guards. I'm also wondering if any aspects of the load has any other relation to node flags. -- Mike Perry

I have Munin data for three servers (each running two Tor instances): https://v-yu.com/servers/munin/network-month.html https://v-yu.com/servers/munin/system-month.html (the start of week 34 on the graphs corresponds to 8/18) (ignore aluminum---it is bandwidth capped and hibernating)
All are non-exit guards. Atlas: https://atlas.torproject.org/#search/reflex One Tor instance each from zinc and silicon went down about a day ago when the servers ran out of memory (memory usage has been climbing with connection counts). The UDP connections in the graphs are unrelated to Tor---they are from NTP pool servers that I am running. I will probably be rebooting all servers soon. Vincent

etc.... Ummmm. I've just had a (paranoid?) thought after reading the recent post from Gordon Morehouse about DDOS. I don't normally expose those stats to the world. Indeed I'd guess a few other people who collect such stats don't either. Now, whilst these stats (along with those from others who respond) might help investigations of the impact of whatever is causing the recent uptick, we may also be giving valuable data to whoever is behind the attack (if we assume it is an attack). As I said, probably paranoid, but if there /is/ a single actor behind this phenomenon then he or she might be delighted to be given such a collection of data points from the network. Oh well.

I publish all our relay stats and I think that this is very helpful for research. Like so much in this universe, it can be used for good and evil. So far, nobody could tell me what evil exactly I am facing by publishing it, so I do. https://www.torservers.net/munin/ Same for the configuration, including firewall rules and whatnot. I strongly believe in transparency. -- Moritz Bartl https://www.torservers.net/
