Alternatively, I would imagine that somewhere someone has written tools to log
performance data over a time-range. I know I have. Currently, I use a series
of scripts that log information concerning CPU, VM, memory, load, network I/O,
disk I/O, and other assorted goodies to various log files. I can then import
these files as CSV's into Excel and look at the pretty graphs.
Alternatively, you could easily parse this data using perl or even awk and
create scripts to monitor for dangerous trends.
There are also commercial packages that do this.
