cpu bottleneck

default alarmdef rule for cpu bottleneck

# The CPU bottleneck symptom default is influenced mostly by the overall
# cpu utilization.  Note that cpu utilization may be high even though
# there is no bottleneck.  The run queue is an indicator processes are
# waiting for cpu resources, and that the cpu may be bottlenecked.
