memory bottleneck

default alarmdef rule for memory bottleneck

# The Memory bottleneck symptom default is triggered by a combination
# of several metrics.  Excessive page outs can be an indicator of memory
# pressure when the memory utilization is high, however memory-mapped
# file writes also generate pageouts.  Under heavy memory pressure, data
# will start to be swapped out.
