•
sample <sample_ID>
—Configure sampled statistics. See
“stats samples,"
for a list of
supported samples.
•
clear
—Clear all data from this sample series.
•
enable
—Enable this sample. Use no stats sample <sample_ID> enable to disable
the sample. See
Table 35 on page 364
for which samples are enabled by default.
•
interval
—Set the amount of time in seconds (1 - 2147483647) between sample
polling for the specified group of sample data.
show stats
alarm [<alarm_ID>]
chd [<CHD_ID>]
cpu
sample [<sample_ID>]
Notes:
•
alarm
—Status of all alarms or the specified alarm, whether or not it is in an error state.
•
chd
—Statistics CHDs settings.
•
cpu
—Basic statistics about CPU utilization: the current level, the peak over the past hour,
and the average over the last hour.
•
sample
—Sampling interval for all samples, or the specified one.
stats alarms
Enable or disable the specified alarm with stats alarm <alarm_ID> enable; the no variant
disables the specified alarm. Set a threshold value for each alarm using the stats alarm
<alarm_ID> rising or stats alarm <alarm_ID> falling commands; the alarm is triggered
when the specified threshold is reached. Alarms that can be enabled or disabled are described
in
Table 33
.
stats alarm States
Alarms can be in one of two states:
•
OK—The alarm is in a normal state.
•
ERROR—The alarm is already triggered and it is in the error state.
You can specify the error-threshold and clear-threshold levels for alarms using the
stats commands; for example:
stats alarm total_byte_rate rising error-threshold 10
stats alarm total_byte_rate rising clear-threshold 1
In this example, after the total_byte_rate stat alarm goes beyond 10, the alarm state
changes to ERROR. The state changes to OK only when the total_byte_rate stat alarm
comes to less than or equal to 1.
stats alarm rate-limit count
Specify three time limits for tracking and, potentially, limiting how many of this type of alarm to
send. The duration and count of each bucket for short, medium, and long are meant to be
