Uptime gives you the current time, the length of time the system has been up, and the average number of jobs in the run queue over the last 1, 5, and 15 minutes (according to the man page). Maybe you are looking at it in a different way. Try setting up sar to see stats from it (see the crontab for sys account) but make sure you read the man page for sar first. Also see man page for uptime.

sar(1M) System Administration Commands sar(1M)
NAME
sar, sa1, sa2, sadc - system activity report package
SYNOPSIS
/usr/lib/sa/sadc [ t n] [ofile]
/usr/lib/sa/sa1 [ t n]
/usr/lib/sa/sa2 [-aAbcdgkmpqruvwy] [-e time] [-f filename] [-i sec] [-s time]
DESCRIPTION
System activity data can be accessed at the special request of a user (see sar(1)) and automatically, on a routine basis, as described
here. The operating system contains several counters that are incremented as various system actions occur. These include counters for CPU
utilization, buffer usage, disk and tape I/O activity, TTY device activity, switching and system-call activity, file-access, queue activ-
ity, inter-process communications, and paging. For more general system statistics, use iostat(1M), sar(1), or vmstat(1M).
sadc and two shell procedures, sa1 and sa2, are used to sample, save, and process this data.
sadc, the data collector, samples system data n times, with an interval of t seconds between samples, and writes in binary format to ofile
or to standard output. The sampling interval t should be greater than 5 seconds; otherwise, the activity of sadc itself may affect the sam-
ple. If t and n are omitted, a special record is written. This facility can be used at system boot time, when booting to a
multi-user state, to mark the time at which the counters restart from zero. For example, when accounting is enabled, the svc:/sys-
tem/sar:default service writes the restart mark to the daily data file using the command entry:
su sys -c "/usr/lib/sa/sadc /var/adm/sa/sa'date +%d'"
The shell script sa1, a variant of sadc, is used to collect and store data in the binary file /var/adm/sa/sadd, where dd is the current
day. The arguments t and n cause records to be written n times at an interval of t seconds, or once if omitted. The following entries in
/var/spool/cron/crontabs/sys will produce records every 20 minutes during working hours and hourly otherwise:
0 * * * 0-6 /usr/lib/sa/sa1
20,40 8-17 * * 1-5 /usr/lib/sa/sa1
See crontab(1) for details.
The shell script sa2, a variant of sar, writes a daily report in the file /var/adm/sa/sardd. See the OPTIONS section in sar(1) for an
explanation of the various options. The following entry in /var/spool/cron/crontabs/sys will report important activities hourly during the
working day:
5 18 * * 1-5 /usr/lib/sa/sa2 -s 8:00 -e 18:01 -i 1200 -A
FILES
/tmp/sa.adrfl address file
/var/adm/sa/sadd Daily data file
/var/adm/sa/sardd Daily report file

NOTES
The sar service is managed by the service management facility, smf(5), under the service identifier:
svc:/system/sar
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser-
vice's status can be queried using the svcs(1) command.
