[processlist]
Nice priorities range from -20 to 19.
Configure nice levels using a comma-separated list.
Nice: Example 1, non-zero is warning (default behavior)
nice_warning=-20,-19,-18,-17,-16,-15,-14,-13,-12,-11,-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19

nice_critical=15,16,17,18,19
