Usage and Notes

This message is sent to all connected clients (and simulators + dataserver?) about once a second to reflect the current statistical details maintained by the simulator.

• PidStat.PID is most likely the operating system process id of the simulator software on the host.
• RegionX and RegionY are the X and Y MAP coordinates, not its global coordinates.
• ObjectCapacity is the number of primitives(tasks) the region can hold. (Usually 15,000)
