Now instead of getting aggregate stats per called function, we have them per function AND per call place. The "byaddr" sort considers the function pointer first, then the call count, so that dominant callers of a given callee are instantly spotted. This allows to get sorted outputs like this: Tasks activity: function calls cpu_tot cpu_avg lat_tot lat_avg h1_io_cb 17357952 40.91s 2.357us 4.849m 16.76us <- sock_conn_iocb@src/sock.c:869

where they're called (e.g. process_stream). The method used to wake them up is also shown. Applets are handled specially and shown as appctx_wakeup. |

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 - BRANCHES to understand the project's life cycle and what version to use - 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)
