       showgraph.cgi - CGI to generate Xymon trend graphs

       showgraph [options]

       showgraph.cgi is	invoked	as a CGI script	via the CGI wrap-

       showgraph.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
       showgraph.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 descrip-
       tion of the "-u"	option.

       lower Set the lower limit of the	graph. See rrdgraph(1) for a  descrip-
       tion 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	gener-
       ate 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 showgraph.cgi with "action=show-
       zoom" 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	showgraph.cgi.

       action=view Generate a single graph image.

	      Loads  the graph configuration file from FILENAME. If not	speci-
	      fied,  the  file	$XYMONHOME/etc/graphs.cfg  is  used.  See  the
	      graphs.cfg(5) for	details	about this file.

	      Loads  the  environment settings defined in FILENAME before exe-
	      cuting the CGI.

	      The top-level directory for the RRD files. If not	specified, the
	      directory	given by the XYMONRRDS 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.

       RRDGRAPHOPTS RRD-specific options for the graph.	This is	usually	set in
       the xymonserver.cfg(5) file.

       graphs.cfg: The configuration file determining how graphs are generated
       from RRD	files.

       graphs.cfg(5), xymon(7),	rrdtool(1)
