Many times we've been missing per-process traffic statistics. While it didn't make sense in multi-process mode, with threads it does. Thus we now have a counter of bytes emitted by raw_sock, and a freq counter for these as well. However, freq_ctr are limited to 32 bits, and given that loads of 300 Gbps have already been reached over a loopback using splicing, we need to downscale this a bit. Here we're storing 1/32 of the byte rate, which gives a theorical limit of 128 GB/s or ~1 Tbps, which is more than enough. Let's have fun re-reading this sentence in 2029 :-) The values can be read in "show info" output on the CLI.
The HAProxy documentation has been split into a number of different files for ease of use. Please refer to the following files depending on what you're looking for : - INSTALL for instructions on how to build and install HAProxy - LICENSE for the project's license - CONTRIBUTING for the process to follow to submit contributions The more detailed documentation is located into the doc/ directory : - doc/intro.txt for a quick introduction on HAProxy - doc/configuration.txt for the configuration's reference manual - doc/lua.txt for the Lua's reference manual - doc/SPOE.txt for how to use the SPOE engine - doc/network-namespaces.txt for how to use network namespaces under Linux - doc/management.txt for the management guide - doc/regression-testing.txt for how to use the regression testing suite - doc/peers.txt for the peers protocol reference - doc/coding-style.txt for how to adopt HAProxy's coding style - doc/internals for developer-specific documentation (not all up to date)
