I do not issue any guarantee that this will work for you.
So this article I am using Arch Linux . As it doesn't come with base installation so I have to get it(sysstat) separately.

Now it puts a crontab entry to run daily on the installed system..although you can control it according your choice..
bhaskar@bhaskar-laptop_07:13:35_Tue Aug 31:/etc/cron.daily> cat sysstat
#!/bin/sh
# Generate a daily summary of process accounting. Since this will probably
# get kicked off in the morning, it would probably be better to run against
# the previous days data.

This package come with so many binary and all of them are very useful tool. I will explain all of them one by one.First tool is callled sar..and it will output like this..

Now bit of explanation is required for the fields it shows which I enumerated below:
Sar is system activity reporter.
%user and %nice refer to your software programs, such as MySQL or Apache.
%system refers to the kernel’s internal workings.
%iowait is time spent waiting for Input/Output, such as a disk read or write. Finally, since the kernel accounts for 100% of the runnable time it can schedule, any unused time goes into %idle.
It come along with another two binary relates sar is called sa1 and sa2.What does this fellows do to sar??
The sa1 script logs sar output into sysstat's binary log file format, and sa2 reports it back in human readable format.Clear!
And the reports it provide kept in a dir called /var/log/sa and file with date attached to it...
bhaskar@bhaskar-laptop_07:25:28_Tue Aug 31:/var/log/sa> ls
sa23 sa24 sa25 sa30 sa31 sar24 sar30
"-W" this flag to sar shows the swap related activity on the system

Anyway you can fuse your terminal reports into the excel sheet to manage thing as the origianl page is shown the way how to do it.Kndly visit the origianl pacakge author page to see the options.
Ok now lets talk about another binary come with package called "pidstat" What it does??
pidstat command is used to monitor processes and threads currently being managed by the Linux kernel. It can also monitor the children of those processes and threads.
on my system it shows the thing going underneath:

"-d" option provide I/O statistics.
Now get the memory utilisation stat through "-r" flag of this binary.

Now lets talk about two very important tool which will provide different way to view things. Those are called "sadc" and "sadf".I will cover one after another below.
SADC:
It is system activity and data collector daemon.Even w can use it manually too!.Sadc command intened to run behind the sar command.Actually it will write the binary format of the statistics it collect day by day and put into a dir i.e /var/log/sadd,where dd stands for the particular day.As the man page said it can only provide local activity,means runs on the same host it installed.
I am putting here few example stright out of the manual page for clear understanding.Here we go:
/usr/lib/sa/sadc 1 10 /tmp/datafile
Write 10 records of one second intervals to the /tmp/datafile binary file.
/usr/lib/sa/sadc -C Backup_Start /tmp/datafile
Insert the comment Backup_Start into the file /tmp/datafile.
So move onto the next tool called sadf.
SADF:
This tool actually dispaly the collected data by sar in different format.Which is wonderful..because you can fuse your data to various places to get lot many information.It will essentially provide XML,CVS format data .
once again I am putting example stright out of the manual page for easy understanding.Here we go:
sadf -d /var/log/sa/sa21 -- -r -n DEV
Extract memory, swap space and network statistics from system activity file 'sa21', and display them in a format that can be ingested by a
database.
sadf -p -P 1
Extract CPU statistics for processor 1 (the second processor) from current daily data file, and display them in a format that can easily be
handled by a pattern processing command.
Hope this will help.
Cheers!
