# Pages

“pages” provide the opportunity to collect graphs of different hosts/services on one page. That way - as an example - you can display the traffic rates of all tape libraries. Regular expressions are possible so you can accomplish a lot with only few definitions - provided that you have appropriate names. The directory specified using “$conf['page_dir']” contains one or more file with the extension ”.cfg”.

Comments start with a hash-sign (#) and are possible within lines as well. Each file contains a “page” definition which specifies the name of the page and it determines whether the following graph definition contains regular expressions or not.
The description behind `page_name` appears in the list of available pages and will be used as title of the browser window. Attention: “host_name” and “service_desc” refer to the name of the file in the perfdata directory, not to the definition in Nagios. Blanks are replaced by underscores (_).

    define page {
           use_regex 1		# 0 = use no regular expressions, 1 = use regular expressions
           page_name test-page	# page description
    }

One or more “graph” definitions follow:

    define graph {
           host_name       host1,host2,host3
           service_desc    Current_Load
    }

Attention: The list of host name will only work if you use `regex 0`!

    define graph {
           host_name       host4
           service_desc    Current_Users
    }

And now some definitions with regular expressions. At first all hosts whose names are starting with “Tape”:

    define graph {
           host_name       ^Tape
           service_desc    Traffic
    }

all hosts whose names are ending with “00”:

    define graph {
           host_name       00$
           service_desc    Load
    }

all services of localhost whose names contain “a” or “o”, respectively:

    define graph {
           host_name       localhost
           service_desc    a|o
    }

all services whose names contain an underscore followed by (at least) three digits on all hosts whose names start with “UX”:

    define graph {
           host_name       ^UX
           service_desc    _\d{3}
    }
