2.Определение команд для проверки

# cd /usr/local/nagios/etc/

1	# cd /usr/local/nagios/etc/

# nano commands.d/check-mail.cfg

1	# nano commands.d/check-mail.cfg

define command {
  command_name check-plain-pop3
  command_line $USER1$/check_pop -4 -t 30 -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$
}

define command {
  command_name check-secure-pop3
  command_line $USER1$/check_spop -4 -t 30 -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$
}

define command {
