Consider putting iostat, vmstat, mpstat in short intervals in file (like 15 seconds, every hour new file [15 240]). Be sure to take notice of disk space required.
Also, you might want to consider installing and configuring sysstat bundle on linux system, using various online resources.
Later on you can analyse those files to see possible problems using ploting for graphs, or perhaps loading into database.
Hope that helps

apache_mod_perl-108~358::mod_perl-2.0.7::docs::api::ApacUser:Contributed Papache_mod_perl-108~358::mod_perl-2.0.7::docs::api::Apache2::Resource(3)
NAME
Apache2::Resource - Limit resources used by httpd children
Synopsis
PerlModule Apache2::Resource
# set child memory limit in megabytes
# default is 64 Meg
PerlSetEnv PERL_RLIMIT_DATA 32:48
# linux does not honor RLIMIT_DATA
# RLIMIT_AS (address space) will work to limit the size of a process
PerlSetEnv PERL_RLIMIT_AS 32:48
# set child cpu limit in seconds
# default is 360 seconds
PerlSetEnv PERL_RLIMIT_CPU 120
PerlChildInitHandler Apache2::Resource
Description
"Apache2::Resource" uses the "BSD::Resource" module, which uses the C function "setrlimit" to set limits on system resources such as memory
and cpu usage.
Any "RLIMIT" operation available to limit on your system can be set by defining that operation as an environment variable with a "PERL_"
prefix. See your system "setrlimit" manpage for available resources which can be limited.
The following limit values are in megabytes: "DATA", "RSS", "STACK", "FSIZE", "CORE", "MEMLOCK"; all others are treated as their natural
unit.
If the value of the variable is of the form "S:H", "S" is treated as the soft limit, and "H" is the hard limit. If it is just a single
number, it is used for both soft and hard limits.
Defaults
To set reasonable defaults for all RLIMITs, add this to your httpd.conf:
PerlSetEnv PERL_RLIMIT_DEFAULTS On
PerlModule Apache2::Resource
