Introduction

This page refers to monitoring facilities that are typically present on a viewer. These are not directly connected with OpenSimulator.

Please add more detail as necessary.

Viewer statistics

The short cut to display this window is CTRL + SHIFT + 1. This shows measures such as viewer frames per second (FPS), Total Frame Time, etc.

Information about a few of these measures is broken out below.

Ping Sim

A typical viewer will send a ping UDP packet (StartPingCheck) to the root region every 5 seconds.

The simulator will respond immediately with a CompletePingCheckPacket. The viewer measures the round-trip time and displays this as the Ping Sim statistic.

If the simulator is on the same computer as the viewer, then you would expect to see a ping time of approximately 10-25 ms. If the simulator is remote, then ping times will be a lot longer as the packet traverses the network.

If ping time is constantly varying, this may indicate an extremely over-loaded simulator or network issues between the viewer and the simulator.

Texture Console

The short cut to display this is CTRL + SHIFT + 3. This will overlay a display on the viewer which details the textures being downloaded and thedownload progress. The number of textures present on the region is the number after the "Textures:" text on the third line of the display. The higher this is, the more graphics memory is required from the viewer and lower performance will be.

See http://wiki.secondlife.com/wiki/Texture_Console for more details.
