# The minimum netdata Out-Of-Memory (OOM) score.
# netdata (via [global].OOM score in netdata.conf) can only increase the value set here.
# To decrease it, set the minimum here and set the same or a higher value in netdata.conf.
# Valid values: -1000 (never kill netdata) to 1000 (always kill netdata).
OOMScoreAdjust=1000

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

# 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).
