Useful Scripts
This is a small script to watch for an OpenSim region simulator under screen in Linux. If the process is missing, a new instance will be started.

JSON User SimStats
As of OpenSim svn 9529 the xtended stats reporting will return a jsonp callback to allow popular javascript toolkits to use the returned data to create ajax monitoring applications in the browser. This is an advantage because after the page is loaded, the browser will interact directly with the region, eliminating traffic through the website (polling the region and servicing the browser). It also allows the creation of mashups to create mini-monitor apps in other pages.
To enable your stats reporting, set the following in your OpenSim.ini...
; Simulator Stats URI ; Enable JSON simulator data by setting a URI name (case sensitive) Stats_URI = "jsonSimStats"
...the URI can be anything you want, and is case sensitive. You can query the URI directly to return a json string to use in php, python, java, etc. or you may use one of the popular javascript toolkits to have OpenSim generate a callback for jsonp. The json serialization carries the following data...

JSON Grid Simstats
Python example to gain the region data from a grid service
- should work but this version not tested -
*reference material*
import hashlib import urllib2 ''' From regions.regionSecret ''' regionsecret = 'fe21314b-6267-44f7-aa1e-6047e1c3f94a' ''' My region host ''' hostName = myregion.host.net ''' My region port ''' hostPort = 9000 ''' create an *UPPERCASE* SHA1 hash from the regionSecret ''' resourceName = str(hashlib.sha1(regionsecret).hexdigest()).upper() regionuri = hostName + ":" + hostPort + "/" + resourceName + "/" ''' data includes TimeZoneName , TimeZoneOffs, UxTime, Memory, Version and OSStatsURI ''' regiondata = simplejson.load(urllib2.urlopen(regionuri)) ''' OSStatsURI is the uri to query the OpenSim instance. retrun ssame data as the user set uri ''' simuri = regiondata['OSStatsURI'] simdata = simplejson.load(urllib2.urlopen(simuri))
