See if your Systems Administrator has installed sar and the associated data collection and reporting crons (man sadc). The default daily report includes memory usage and a lot more, but it would be better to make your own custom report which contains just what you need (for example sar -f /usr/adm/sa/sa?? where ?? is the day of the month). Not sure if you would need root access to run your own reports.
The main issue with historical reporting as distinct from dynamic monitoring is that you must have an automated background process to save the data. If not, your whole life will get taken up with running monitor processes.
Wherever possible I prefer to automate any management reporting and then email the report direct from the server. The management like to read short summary reports which clearly state that the system has no problems, or clearly state that the system needs upgrade or replacement.
If you need a fine-detail report for you own purposes, then send it to yourself or your team.
Sometimes you have to plot graphs in Excel and this means taking some serious time to develop scripts which produce data files which require the absolute minimum of effort to plot the data in Excel. To this end I use ftp to deposit the data on a Microsoft Server and have a ready-prepared Excel spreadsheet to plot the graph.

niffconfig
niffconfig(8) System Manager's Manual niffconfig(8)
NAME
niffconfig - Configuration program for the Network Interface Failure Finder (NIFF)
SYNOPSIS
/usr/sbin/niffconfig [-a] [-m] [-r] [-s] [-u] [-v] [-d num] [-o num] [-t num] [interface1 interface2...]
OPTIONS
Adds an interface or interfaces, specified by the interface parameter. You cannot specify the -a option with the -m, -s, -r, or -u options.
Specifies the time period, in seconds, that the traffic monitor thread uses between reads of the interface counters when it suspects there
is a connectivity problem. This number must be smaller than the number given for the -t option. The default time period is 5 seconds. If
num is not specified, niffconfig uses the default. Specifies the total number of traffic-free seconds that must elapse before the traffic
monitor thread determines that a network interface has failed. This number must be at least the sum of the -d option and two times the -t
option. That is, given the default time period for -d and -t, the -o option must be at least 20 seconds. The default time period for this
option is 60 seconds. If num is not specified, niffconfig uses the default. Modifies the timing parameters of an interface that is already
being monitored. Typically, this option is specified along with one or more of -t num, -d num, or -o num options. If none of these parame-
ters are specified, the default value is used. You cannot specify the -m option with the -a, -s, -r, or -u options. Stops monitoring the
specified interface. Obtains the status of the specified interface. Specifies the time period, in seconds, that the traffic monitor
thread delays between reads of the interface counters when the network is running normally. The default time period is 20 seconds. If num
is not specified, niffconfig uses the default. Displays the status of all interfaces currently being monitored to standard out (stdout).
Displays the status, timer values, and description (verbose mode) of all interfaces currently being monitored to standard out (stdout).
DESCRIPTION
The niffconfig command arranges for one or more network interfaces to be monitored for possible loss of connectivity. Timing parameters
that govern how quickly an interface can be declared suspect or dead may be manipulated with this command. You can specify multiple inter-
faces, separated by a space, on the command line. Note, you must be superuser to use the niffconfig command.
Except for the -u and -u options, all niffconfig options require one or more network interfaces to be specified.
EXAMPLES
To add the tu0 and tu1 interfaces to the list of monitored interfaces, enter: # niffconfig -a tu0 tu1 To change the time it takes to
declare failure on the tu1 interface to 90 seconds, enter: # niffconfig -o 90 tu1 To display the status of all interfaces that are being
monitored: # niffconfig -u To stop monitoring the tu0 interface: # niffconfig -r tu0
