We have the first version of our internal relay stats manager live. There were a number of questions about how we collect and record this data, so I wanted to take a moment to give a little insight.
Our haproxy stack consists of three haproxy containers:
TCP Server
/ \
HTTP Server 0 HTTP Server 1
TCP Server- Despite the name, this server runs in HTTP mode. Its only job is to route traffic to the available HTTP Server 0 or 1.
