Linux Identify cause of high resource usage

hello all,

on linux servers sometimes any of these resources (cpu,memory,disk) get a spike when you are not in front of the server.

the duration of these spikes might be 5 mins or even whole weekend.

my question is there a good way of capturing the events that caused these issues ( cpu or memory) that can later be used to investigate and find a solution.

p.s am not talking about monitoring tools like caccti,nagios etc.

thanks
