# Valid policies: other (the system default) | batch | idle | fifo | rr
# To give netdata the max priority, set CPUSchedulingPolicy=rr and CPUSchedulingPriority=99
CPUSchedulingPolicy=batch

# This sets the scheduling priority (for policies: rr and fifo).
# Priority gets values 1 (lowest) to 99 (highest).
#CPUSchedulingPriority=1

# For scheduling policy 'other' and 'batch', this sets the lowest niceness of netdata (-20 highest to 19 lowest).
