== 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...
 +
 +
  {"AssetsInCache":5.0,"TimeAfterCacheMiss":0.0,"BlockedMissingTextureRequests":0.0,"AssetServiceRequestFailures":0.0,
 +
"abnormalClientThreadTerminations":0.0,"InventoryServiceRetrievalFailures":0.0,"Dilatn":0.967380821704865,"SimFPS":55.0,

Here is an example I have running, and will leave up for a while (
 +
http://ascent.bluewallgroup.com/jtest.html ) . You can use it as a starting
 +
place to create monitors for your regions.

Sunrise/Sunset Table

This seems to always change, but here is a set of lsl lists with the current sunrise/sunset times in GMT

list SunRise = [5400.0,19800.0,34200.0,48600.0,63000.0,77400.0];
list SunSet = [1800.0,16200.0,30600.0,45000.0,59400.0,73800.0];

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...

 {"AssetsInCache":5.0,"TimeAfterCacheMiss":0.0,"BlockedMissingTextureRequests":0.0,"AssetServiceRequestFailures":0.0,
"abnormalClientThreadTerminations":0.0,"InventoryServiceRetrievalFailures":0.0,"Dilatn":0.967380821704865,"SimFPS":55.0,
"PhyFPS":47.1628913879395,"AgntUp":0.0,"RootAg":0.0,"ChldAg":0.0,"Prims":0.0,"AtvPrm":0.0,"AtvScr":0.0,"ScrLPS":0.0,
