Overview

This is a set of scripts you can use to create a simple Avatars United application - a "gadget".

This gadget will display statistics from a Second Life region (how many avatars, FPS/Time Dilation values, server hostname and prim usage). Here's how it will appear in your AU page: Aulolmonitor.jpg

To re-create this application you will need:

  • an AU developer account
  • Linux-based web hosting for your gadget (a few kbytes, but you will also need both Crontab and Bash scripts support)
  • land permissions (details needed - to do)

Steps

Here's what you should do:

  1. look at Avatars United dev docs ;-)
  2. customize and put sensor in your region - (details needed - to do)
    1. you can get a free copy of the sensor at my LOL region: http://slurl.com/secondlife/LOL/81/49/22
  3. customize and host the gadget XML file - (details needed - to do)
  4. customize the Bash script, host it and put it into your Crontab -or do something similar- in order to periodically query your sensor and update the gadget XML file with fresh data
  5. follow Avatars United dev docs to create your application - (details needed - to do)

Code

Gadget XML source

Note: the 2 lines that begin with "A LOL ci sono..." will be periodically updated by the Bash script with actual data from your region.

Bash script

It calls the in-world LSL prim, asks for region stats, dumps the results to a file, and updates the XML gadget you can find above.
