[tor-relays] Overload data for Exit vs Non-Exit (and Guard vs Middle)?

[Mike Perry]

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/index.html#network
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.

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.
