NAME

       HATop - interactive ncurses client for haproxy

SYNOPSIS

       hatop -s SOCKET [OPTIONS]

DESCRIPTION

       HATop  is  an  interactive  ncurses  client  and real-time monitoring, statistics displaying tool for the
       HAProxy TCP/HTTP load balancer.

       HATop's appearance is similar to top(1). It  supports  various  modes  for  detailed  statistics  of  all
       configured  proxies  and  services in near realtime.  In addition, it features an interactive CLI for the
       haproxy unix socket.  This allows administrators to control the given  haproxy  instance  (change  server
       weight,  put  servers  into  maintenance mode, ...) directly out of hatop (using keybinds or the CLI) and
       monitor the results immediately.

       HATop uses a unix domain socket to communicate with HAProxy.  This  can  be  configured  in  the  HAProxy
       configuration  using  the "stats socket" option.  To enable all of HATop's features the "level" parameter
       of this option should be set to "admin".
