Issue with nagios notify ping 'WARNING'

I installed nagios version 4.0.2 on CentOS 6.5 64bit from source, the installation succeeded  and nagios could start. However there is issue with notification when nagios checking 'check_ping' command, the host is alive and packet lost is 0%, nagios still send alert to my email. This is quite annoying.

Email notification like this:

***** Nagios *****

Notification Type: RECOVERY

Service: PING

Host: x.x.x.x

Address: x.x.x.x

State: OK

Date/Time: Wed Feb 26 16:08:46 ICT 2014

Additional Info:

PING OK - Packet loss = 0%, RTA = 341.55 ms

After searching around, I found solution related to check_ping command defined in /usr/local/nagios/etc/objects/commands.cfg. You need to make the check_ping command definition the same as check-host-alive. Otherwise you will get the same notification when it happens next.

define command{
        command_name    check-host-alive
        command_line    $USER1$/check_ping -H $HOSTADDRESS$ -w 3000.0,80% -c 5000.0,100% -p 5

        }

define command{
        command_name    check_ping
        #command_line    $USER1$/check_ping -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$ -p 5
        command_line    $USER1$/check_ping -H $HOSTADDRESS$ -w 3000.0,80% -c 5000.0,100% -p 5

        }
