Nagios could not retrieves data from Windows.

Basically, there's no need to configure anything on LINUX operating systems for sending information/ data to Nagios. Unfortunately, Windows Operating systems need to be install with additional software which is NSClient++ that can be download it for free from http://www.nsclient.org/nscp

From my experience, I have install this application on Windows Server 2003, 2008 and Windows 7.

It working fine.

Nagios could not send notification through email

Basically, OSCC had customize Nagios using Postfix for sending email. Unfortunately the email could not go through. After all the Googling the solution is quite simple.

Just edit file name
/etc/postfix/main.cf


add a new line with
relayhost = mpkmail.rmp.gov.my


Below are template provide by OSCC;

# See /usr/share/postfix/main.cf.dist for a commented, 
# more complete version


# Debian specific:  Specifying a file name will cause the first
# line of that file to be used as the name.  The Debian default
# is /etc/mailname.
# myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no
