If you're doing custom installs of Nagios for clients, you may want to have a custom header and/or footer displayed in the output of the CGIs. This is particularly useful for displaying support contact information, etc. to the end user.
How Does It Work?
You can include custom headers and footers in the output of the CGIs by dropping some appropriately named HTML files in the ssi/ subdirectory of the Nagios HTML directory (i.e. /usr/local/nagios/share/ssi).
Custom headers are included immediately after the <BODY> tag in the CGI output. Similarly, customer headers are included immediately before the closing </BODY> tag.
There are two types of customer headers and footers:
You are not required to use any custom headers or footers. You can use only a global header if you wish. You can use only CGI-specific headers and a global footer if you wish. Whatever you want. Really.
