# The minimum netdata Out-Of-Memory (OOM) score.
# netdata (via [global].OOM score in netdata.conf) can only increase the value set here.

# Valid values: -1000 (never kill netdata) to 1000 (always kill netdata).

# To give netdata the max priority, set CPUSchedulingPolicy=rr and CPUSchedulingPriority=99
