We won't be able to write the entire script for you. We will give the key idea and you can develop on it.

First executing a command in the remote server.

Code:
cgi@tioman> (/home/cgi) $ ssh cgi@123.122.32.22 -C "df -h"
The authenticity of host '123.122.32.22 (123.122.32.22)' can't be established.
RSA key fingerprint is 72:a9:6d:a6:1b:fc:51:bf:06:bd:7f:35:2c:93:61:ee.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '123.122.32.22' (RSA) to the list of known hosts.

To avoid typing password, you can use ssh keys.

Sending mails can be done using mailx command or anyother mail utilities. First of all, you try to get the information from all your servers.
1. make a text file which will have list of the servers.
2. Try to establish ssh key authentication between your machine to all servers.
3. Loop through the server list and execute the ssh command and store the output in a file.
4. Mail the file.

upsimage.cgi

UPSIMAGE.CGI(8) 						    NUT Manual							   UPSIMAGE.CGI(8)

NAME

       upsimage.cgi - Image-generating helper for upsstats.cgi

SYNOPSIS

       upsimage.cgi

	   Note
	   As a CGI program, this should be invoked through your web server. If you run it from the command line, it will either complain about
	   unauthorized access or spew a PNG at you.

DESCRIPTION

       upsimage.cgi generates the graphical bars that make up the right side of the page generated by upsstats.cgi(8). These represent the current
       battery charge, utility voltage, and UPS load where available.

       The images are in PNG format, and are created by linking to Boutell's excellent gd library.

ACCESS CONTROL

       upsstats will only talk to upsd(8) servers that have been defined in your hosts.conf(5). If it complains about "Access to that host is not
       authorized", check that file first.

FILES

       hosts.conf(5)

SEE ALSO

       upsd(8), upsstats.cgi(8)
