Enable or disable the specified alarm. There are three alarms that can be enabled or
disabled: cpu_util_indiv (CPU utilization too high), paging (paging activity
too high), and fs_mnt (filesystem low on free space).
stats alarm rising error-threshold
stats alarm rising clear-threshold
stats alarm falling error-threshold
stats alarm falling clear-threshold
Change the thresholds which will initiate or terminate (clear) the specified alarm.
New alarms cannot be added through this interface, only existing ones can be
changed.
The units for the cpu_util_indiv alarm are hundredths of a point of the one-
minute load average. For example, setting it to 100 will cause an alarm if the one-
minute load average is ever over 1.0 when it is sampled.
The units for the paging alarm are number of pages read from or written to the
swap partition. The alarm is on the amount of paging activity that has occurred over
the past 20 seconds.
