Re: email Alert & webconfig [need help!]

to implement a web-based configuration I think that it's not very easy because when you change a config from web you will ensure that only for newer requests will be used new parameters. I think that an easy way to do it, is make a gui written in php/perl where you access via web and when you modify something it modify haproxy.cfg and reload haproxy process.
For emaill-alert feature on haproxy i think that you will modify these files: 1- include/types/global.h

    Add some member vars in global struct ex.

     struct global {
          char* alert_cmd;
2- src/cfgparse.c
     in int cfg_parse_global(const char *file, int linenum, char
**args, int inv)
     before last else { add
    else if (!strcmp(args[0], "alert_cmd")) {
           global.alert_cmd = strdup(args[1]);
3- src/checks.c

   in static void set_backend_down(struct proxy *be)    add:

      if ( global.alert_cmd )
         system( global.alert_cmd );

This's only an example and you will do more check's and other stuff, but I believe that it works only modifying these files. Bye
