Usage
This command provides the ability to track key session-related statistic information over time. This
information can be used as part of system performance monitoring and capacity planning.

Important:
The information provided in the output of this command requires that bulk statistics functionary be
enabled on the system. Refer to the System Administration Guide for more information on configuring and enabling
bulk statistics support.

The output of this command displays historical data collected at various sample intervals. The interval length
is 15 minutes and is not user-configurable. Up to 192 samples (two days’ worth of data) are maintained.
is 15 minutes and is not user-configurable. Up to 192 samples (two days’ worth of data) are maintained.
Important:
Data collection is “best-effort” over these intervals. Data is preserved on the SMC or MIO card
switchovers. As with all counters, certain session failures can cause inaccuracies with counters, including counters
which appear to go backwards.
which appear to go backwards.
Each sample is identified by a timestamp that displays the approximate time the data was gathered. the
timestamp is in the format YYYY:MM:DD:hh:mm:ss.
Data acquired during the sample may be marked with an “S” appended to the end of the timestamp or to the
counter value. The “S” indicates that the data is suspect (potentially bad). Occurrences of this result from
events like changes to the real time clock, which can cause an interval to be an atypical length. Instances of
suspect data should be rare. Additionally, there may be occasions in which a sample may be marked as
“invalid”. “invalid” identifies bad data, a situation that could result when the polling has not run long enough,
or because of an unexpected error retrieving data.
Since baseline values must be obtained prior to collecting interval samples, the first interval of data will not
be available until up to twice the interval period.
