Query CPU Load:
Let(
[
// query load
r1 = MBS( "SystemInfo.CPULoad" );
// separate values
system1 = JSONGetElement ( r1; "system" );
idle1 = JSONGetElement ( r1; "idle" );
user1 = JSONGetElement ( r1; "user" );
total1 = user1+idle1+user1;
// make a 0.5 second pause
t = MBS("Time.Sleep"; 500);
// now query again
r2 = MBS( "SystemInfo.CPULoad" );
// separate values
system2 = JSONGetElement ( r2; "system" );
idle2 = JSONGetElement ( r2; "idle" );
user2 = JSONGetElement ( r2; "user" );
total2 = user2+idle2+user2;
// calculate deltas
deltaTotal = total2 - total1;
deltaSystem = system2 - system1;
deltaIdle = idle2 - idle1;
deltaUser = user2 - user1;
// and calculate the percentage used
load = (deltaSystem+deltaUser) / deltaTotal
