Implemented October 15,2017 by UbitUmarov in GIT# 3d6553afeee3d4605851b6f336c17d5a6b07c6ad - Commit 3d6553

Example(s)
Simple Script (displays only the integer such as 234652064)
// Simple Unformatted Output
 
integer TotMemUsed;
 
default
{
    state_entry()
    {
        TotMemUsed = osGetSimulatorMemoryKB();
        llSetText( (string)TotMemUsed+" Memory by the OpenSimulator Instance", <0.0, 1.0, 0.0>, 1.0 );
    }
 
    touch(integer number)
    {
        TotMemUsed = osGetSimulatorMemoryKB();
        llSetText( (string)TotMemUsed+" Memory by the OpenSimulator Instance", <0.0, 1.0, 0.0>, 1.0 );
    }
}

Extended with some formatting: (displays as 234.652 Mb)

// Simple formatted Output shows either MB or GB as applicable
// ==== GET Memory Integer and Format for Display ====
 
GenStats()
{
    // Get Memory and format it
    string TotalMem;
    string TotMemUsed;
    string TxtTail =" used by OpenSimulator Instance";
 
    TotMemUsed = (string)osGetSimulatorMemoryKB();
    integer Len = llStringLength(TotMemUsed);
 
    if (Len == 5) // ##.### MB
    {
        string Mem1 = llGetSubString(TotMemUsed, 0, 1);
        string Mem2 = llGetSubString(TotMemUsed, 2, 4);
        TotalMem = Mem1 + "." + Mem2 + "\nMb"+TxtTail;
    }
 
    else if (Len == 6) //###.### MB
    {
        string Mem1 = llGetSubString(TotMemUsed, 0, 2);
        string Mem2 = llGetSubString(TotMemUsed, 3, 5);
        TotalMem = Mem1 + "." + Mem2 + "\nMb"+TxtTail;
    }
 
    else if (Len == 7) //#.### GB
    {
        string Mem1 = llGetSubString(TotMemUsed, 0, 0);
        string Mem2 = llGetSubString(TotMemUsed, 1, 3);
        TotalMem = Mem1 + "." + Mem2 + "\nGb"+TxtTail;
    }
 
    else if(Len == 8) //##.### GB
    {
        string Mem1 = llGetSubString(TotMemUsed, 0, 1);
        string Mem2 = llGetSubString(TotMemUsed, 2, 4);
        TotalMem = Mem1 + "." + Mem2 + "\nGb"+TxtTail;
    }
 
    llSetText(TotalMem, <0.0, 1.0, 0.0>, 1.0 );
}
 
default
{
    state_entry() // display @ start
    {
        GenStats();
    }
 
    touch(integer number) // refresh on touch
    {
        GenStats();
    }
}

More accurate conversion from KB to MB.

GB that way, tested against actual usage reported by the system.

// Simple Formatted Output
 
default
{
    state_entry()
    {
        llSetTimerEvent(5.0);
    }
 
    timer()
    {
        float TotMemUsed = osGetSimulatorMemoryKB();
 
        if (TotMemUsed > (1024*1024))
        {
            TotMemUsed = TotMemUsed / (1024 * 1024);
            llSetText("~" + (string)TotMemUsed + " GB", <1.0, 1.0, 1.0>, 1.0);
        }
 
        else if (TotMemUsed > 1024)
        {
            TotMemUsed = TotMemUsed / 1024;
            llSetText("~" + (string)TotMemUsed + " MB", <1.0, 1.0, 1.0>, 1.0);
        }
    }
}

Informations
This allows working around the fact that osGetSimulatorMemory() reports at most 2GB. This one limit is now 2TB, should be enough for a while
