UNIX for Dummies Questions & Answers

Hello geeks once again, many thanks for help in times past, you guys are awesome!

But am here again, but now this is way heavy for me. Find below for my challenge:

*** I need to collect CPU & RAM stats across 26 servers.

*** I don't have the luxury of deploying an NMS, if I had it would have been easy

*** I need the average of these stats on a weekly basis so that I can plot them through excel.

Any idea how to get this done, i thought of using Bash scripting but hey 26 servers is not a joke! I just started learning Python but now time is not on my side, I need some demo before thursday next week.

Any help will be appreciated, am thinking of collectd but am not so sure of it's capabilities.

What systems are these servers?

Here's a start. You can automate ssh to be passwordless with keys easily enough.

Code:

while read SERVER
do
        ssh $SERVER exec /bin/sh -s <<"EOF"
shell code to send to server
EOF
done < list-of-servers > list-of-data

Hello Corona688,

Many thanks for the code...

These boxes are Oracel SUN/HP Blade Cluster Servers running Suse Linux.

My main concern now is how to organize the output for over 26 servers in an orderly manner to produce a weekly report/summary, just that have not done sthg this deep before.

Will appreciate any advice/input.

Show the input you have and show the output you want.
