Confused by stats page

Looking for some criticism/critique on my setup as it’s me and the walls here… Also trying to make sense of what I’m seeing on the stats page… Hopefully I’m not shooting myself in the foot somehow…

running haproxy out of runit with a finish script to dump the stats…

the run file fwiw:

exec
chpst -o 65536
chpst -e env
/usr/bin/haproxy -W -f /etc/haproxy/local-haproxy.cfg

I’m initially confused with the stats of privoxy vs squid if it’s in static-rr, Session rate Max looks balanced… but Sessions current and Sessions Max look very different from each other… What does that mean (in my case) of where I’m using haproxy in front of two forward proxies…

the haproxy machine is Archlinux with 4.19.72-1-lts kernel as is the 10.20.0.33 machine. This machine is virtual, 0.33 is physical. I also have a tweaked ‘rc.local’ (Arch people seem to hate the ‘old ways’…)

I can share if it might be anything applicable…

Also on the frontend portion of the stats… does Max 60 mean 60 unique users/ips?

Open to questions or criticism…

Thanks in advance.
