A gadget is a script which generates a * dynamic image for visualizing things as graphs in NagVis. * This one was inspired by "fs_usage_bar" (Copyright Richard Leitner) * http://exchange.nagvis.org/exchange/Gadgets/Filesystem-Usage-Bar/ * * The gadget gets its data from the NagVis frontend by parameters. This * gadget only needs the "perfdata" parameter * The values are accessible using the array aPerfdata. The structure is * shown in gadgets_core.php. * The behaviour of the gadget can be influenced by two directives in the * service definition of the map config file: * gadget_scale=n (n being the size of the graph(s) in percent, default = 100) * gadget_opts=option=value (multiple options are separated by spaces) * option is one of the following: * columns=n * number of columns of graphs (if applicable), default is 3 * string=s * s is a string the perfdata label has to contain * current=<0|1> * 1 = show the current value along with the label (default) * label=<0|1> * 1 = show host name/performance label in the last line of the graph * (1 is default) * NagVis also passes the following parameters to the gadget using the array * $aOpts: * - name1: Hostname * - name2: Service description * - state: Current state * - stateType: Current state type (soft/hard) * This value is ignored as the performance data might contain * several values * - scale: Scale of the gadget in percent * This value is ignored in favour of gadget_scale * *****************************************************************************/ /** * Dummy perfdata for WUI * * This string needs to be set in every gadget to have some sample data in the * WUI to be able to place the gadget easily on the map * It has to be set BEFORE including gadgets_core.php ******************************************************************************/ $sDummyPerfdata = 'config=20%;80;90;0;100'; /** * Needs to be configured to tell gadgets_core.php how to handle the outputs * e.g. in case of error messages.
