       hobbit-hostgraphs.cgi - CGI program to show multiple graphs




       hobbit-hostgraph.cgi  is  invoked  as  a  CGI  script  via  the hobbit- CGI wrapper.

       If no parameters are provided when invoked,  it  will  present  a  form
       where  the  user can select a time period, one or more hosts, and a set
       of graphs.

       The parameters selected by the user are passed to a  second  invocation
       of  hobbit-hostgraph.cgi,  and  result  in  a webpage showing a list of
       graph images based on the trend data stored about the hosts.

       If multiple graph-types are selected, hobbit-hostgraph.cgi will display
       a list of graphs, with one graph per type.

       If  multiple  hosts  are selected, hobbit-hostgraph.cgi will attempt to
       display a multi-host graph for each type where the graphs for all hosts
       are  overlayed  in  a single image, allowing for easy comparison of the

       The hostlist uses the PAGEPATH cookie provided  by  Xymon  webpages  to
       select the list of hosts to present. Only the hosts visible on the page
       where hobbit-hostgraph.cgi is invoked from will be visible.

       The resulting graph page can  be  bookmarked,  but  the  bookmark  also
       fixates the time period shown.


              Loads  the  environment defined in FILENAME before executing the
              CGI script.


       This utility is experimental. It may change  in  a  future  release  of

       It  is  possible for the user to select graphs which do not exist. This
       results in broken image links.

       The set of  graph-types  is  fixed  in  the  server/web/hostgraphs_form
       template and does not adjust to which graphs are available.

       If  the  tool  is  invoked directly, all hosts defined in Xymon will be
