Check servers state via munin generated RRDs data

Setup

1. Add a new command in nagios

   check munin ### module / warn / crit

   define command {
   command_name check_munin
   command_line $USER1$/check_munin_rrd.pl -H $HOSTALIAS$ -d $HOSTALIAS$ -M $ARG1$ -w $ARG2$ -c $ARG3$ }

   check munin ### submodule / warn / crit

   define command {
   command_name check_munin_submodule command_line $USER1$/check_munin_rrd.pl -H $HOSTALIAS$ -d $HOSTALIAS$ -M $ARG1$ -S $ARG2$ -w $ARG3$ -c $ARG4$ }

2. Define services

   check the disks

   define service {
   use generic-service
   hostgroup_name my_group
   service_description DISK_munin
   check_command check_munin!df!75!90
   }

   check the load

   define service {
   use generic-service
   hostgroup_name my_group
   service_description LOAD_munin
   check_command check_munin!load!4!8
   }

3. Fork it
