NOTE Dashboard configuration is stored in the /etc/config/config.xml file. Each configured dashboard
will increase the config file. If this file gets too big, you can run out of memory space on the
console server.
11.5.2 Creating custom widgets for the Dashboard
To run a custom script inside a dashboard widget:
Create a file called widget-<name>.sh in the folder /etc/config/scripts / where <name> can be anything.
You can have as many custom dashboard files as you want.
Inside this file you can put any code you wish. When configuring the dashboard, choose widget-<name>.sh
in the drop-down list. The dashboard will run the script and display the output of the script commands on
the screen inside the widget.
The best way to format the output would be to send HTML commands back to the browser by adding
echo commands in the script:
echo '<table>'
You can run any command and its output will be displayed in the widget window directly.
Below is an example script which writes the current date to a file, and echo's HTML code back to the
browser. The HTML code gets an image from a URL and displays it in the widget.
#!/bin/sh
date >> /tmp/test
echo '<table>'
echo '<tr><td> This is my custom script running </td></tr>'
echo '<tr><td>'
echo '<img src="http://www.vinras.com/images/linux-online-inc.jpg">'
echo '</td></tr>'
echo '</table>'
exit 0
