CPU, memory and disk stats

What do you mean with Max, Min and Avg? These are values that implies a continuous monitoring of system resources in a certain range of time.
Once collected all the info (maybe in a logfile) you could parse the output (awk?) and produce the stats you need.
For cpu and memory usage you can have a look at vmstat command, for disks try iostat. However, maybe there's a better utility which I don't know that can do it all

passenger-memory-stats
passenger-memory-stats(8) Administration Commands passenger-memory-stats(8) NAME
passenger-memory-stats - reports a snapshot of the Apache and Phusion Passenger memory statistcs SYNOPSIS
passenger-memory-stats DESCRIPTION
passenger-memory-stats allows you to easily analyze the real memory usage of Phusion Passenger and Apache. Process inspection tools such as ps and top are useful, but they rarely show the correct memory usage. The real memory usage is usually lower than what ps and top report. There are many technical reasons why this is so, but an explanation is beyond the scope of this page. We refer the interested reader to operating systems literature about virtual memory and copy-on-write. When you run this tool the Private or private dirty RSS field shows the real memory usage of processes. ENVIRONMENT VARIABLES
HTTPD The full filename to the Apache executable. By default, Passenger will attempt to autodetect the Apache executable. If autodetection fails for whatever reason, then Apache processes will not be shown in the memory statistics. In that case, you may manually specify the location to the Apache executable using this environment variable. SEE ALSO
