Description

fai-monitor receives messages from all install clients on port 4711 and prints them to stdout.

Name

       fai-monitor - fai monitor daemon

Notes

       Normally, the output will be piped to fai-monitor-gui, a GUI which displays all information.

       fai-monitor  reads  variables  from /var/log/fai/variables (key=value pair format) and replies to request
       from clients if they have the format: VARIABLE  <VARNAME>.  For  e.g.  if  the  clients  sends  "VARIABLE
       FAI_VERSION",  fai-monitor  will  reply  with OK and the value of this variable (e.g. "OK 4.5.6") if this
       variable is defined, otherwise it will  reply  with  UNKNOWN  and  repeats  the  VARNAME  (e.g.  "UNKNOWN
       FAI_VERSION").
