Statistics

This section provides the syntax for system statistics commands, along with an explanation of the

functionality of each command.

stats clear

stats clear-all
stats sample clear
stats chd clear
stats alarm clear

Clear all memory of the specified sample, computed historical data-point (CHD), or alarm, or of all

of those together. Clearing a sample or CHD deletes all of the gathered data. Clearing an alarm

resets it to a non-error state, clears the watermarks, and forgets the event history.

stats sample interval

Change the amount of time between samples for the specified group of sample data.

stats alarm

[no] stats alarm enable

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

(file

system 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.
