Does everyone else just accept the defaults for yellow and red?
No, they are only really applicable to hosts with fewer than 4 cores.
If not,
how do you increase it?
We set yellow to about 2-4 times the number of CPU cores, and red to about 4-8 
times number of cores (depending on the role).

Unfortunately, load average is not a great measure of how busy the CPU really 
is, it would be much better to be able to alarm on vmstat data ...
