hobbitgraph.cgi - CGI to generate Xymon trend graphs
hobbitgraph.cgi is invoked as a CGI script via the hobbitgraph.sh CGI
hobbitgraph.cgi is passed a QUERY_STRING environment variable with the
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
"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.
hobbitgraph.cfg: The configuration file determining how graphs are
generated from RRD files.
