       hobbitgraph.cgi - CGI to generate Xymon trend graphs


       hobbitgraph [options]


       hobbitgraph.cgi  is  invoked as a CGI script via the CGI

       hobbitgraph.cgi is passed a QUERY_STRING environment variable with  the
       following parameters:

       host Name of the host to generate a graph for

       service Name of the service to generate a graph for

       disp  Display-name of the host, used on the generated graphs instead of

       graph Can be "hourly", "daily", "weekly" or  "monthly"  to  select  the
       time period that the graph covers.

       first  Used  to  split  multi-graphs  into multiple graphs. This causes
       hobbitgraph.cgi  to  generate  only  the  graphs  starting   with   the
       "first’th" graph and continuing for "count".

       count Number of graphs in a multi-graph.

       upper  Set  the  upper  limit  of  the  graph.  See  rrdgraph(1)  for a
       description of the "-u" option.

       lower Set  the  lower  limit  of  the  graph.  See  rrdgraph(1)  for  a
       description of the "-l" option.

       graph_start  Set the starttime of the graph. This is used in zoom-mode.

       graph_end Set the end-time of the graph. This is used in zoom-mode.

       action=menu Generate an HTML page with links to 4 graphs,  representing
       the  hourly,  weekly,  monthly  and  yearly  graphs.  Doesn’t  actually
       generate any graphs, only the HTML that links to the graphs.

       action=selzoom Generate an HTML page with link  to  single  graph,  and
       with  JavaScript code that lets the user select part of the graph for a
       zoom-operation.   The   JavaScript   invokes    hobbitgraph.cgi    with
       "action=showzoom" to generate the zoomed graph webpage.

       action=showzoom  Generate  HTML  with a link to the zoomed graph image.
       This link goes to an "action=view" invocation of hobbitgraph.cgi.

       action=view Generate a single graph image.


              Loads  the  graph  configuration  file  from  FILENAME.  If  not
              specified, the file $BBHOME/etc/hobbitgraph.cfg is used. See the
              hobbitgraph.cfg(5) for details about this file.

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

              The top-level directory for the RRD files. If not specified, the
              directory given by the BBRRDS environment is used.

              Instead of returning the image via the CGI  interface  (i.e.  on
              stdout), save the generated image to FILENAME.

              Enable debugging output.


       QUERY_STRING Provided by the webserver CGI interface, this decides what
       graph to generate.

       generated from RRD files.
