System tools
 

I would like to have a tools ,application that can periodically record the system resources - memory utilization , CPU utilization , daily harddisk size checking report , user login report etc , this report is for me and my boss to monitor the resource usage status , execpt writing script , is there any tools/applicaton can periodically generate such kind of report ?

does anyone has the script that can gerenate the above report , if yes, I am very thanks if you can post there . Thx in advance.

I would just tend to write a script to mail the output of this for example:
df -h
sar 5 5
top -b -n 1

I tried the above command, it is great and fine, however , I want to have another items shown on the report, eg. the average CPU loading, average memory utilization , the growth rate of the harddisk utilization ( eg. total size of hd is 10G , if there is 100M growth , then the growth rate is 1% ) , the IP traffic ( how many bytes is in and out the server ) .
does anyone has existing such similiar script ? do you mind to help to make it. I am very thanks if someone can help . thanks in advance.
