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
