# This alarm monitors two file systems and sends an alert when the space
# utilization on a given filesystem exceeds the given value.
#
# Initialize the variables root_util and var_util which will hold the
# current FS_SPACE_UTIL value.  The first time they are accessed, they will
# be initialized to zero.  Loop through the filesystem each interval and save
# the FS_SPACE_UTIL for each one.  Send an alert if the space utilization
# exceeds the given threshold.  A repeat alert will be sent every 30 minutes

# The Network bottleneck symptom default relies on general throughput
# metrics.  Not all network interfaces report collision data.  To be
# useful as a bottleneck indicator, the rate thresholds should be
# adjusted based on values seen in historical data for a particular
# system or network.  For example, 100mbit networks cannot handle as
# high packet rates without a bottleneck than can gigabit networks.

# 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.
