Hello,

Does anyone know a script which can gather information like uptime, disk usage, cpu usage, etc. from multiple servers and output the information on a single server (the one being accessed from)?

Just like http://netsaint.kirenet.com

Thank you,
Marin Micoriciu

Sure one can write such script, but ulr http://netsaint.kirenet.com uses diffrent software and not scripting... here is what i do to find out uptime and what users are doing between multiple server

RH1-box1

RH2-box2

Suse-box3

Debian-mysystem

At Debian-mysystem i have script like

Code:

#!/bin/sh
BOX="IP1 IP2 IP3 IP4"
USR="jadmin"
for ip in $BOX
do
echo "Server Uptime and Load @ $ip"
 ssh $USR@$ip uptime 
 ssh $USR@$ip w
echo "-----------------------------------------------------------"
done

Note that I have ssh keys for user jadmin from my Debian-mysystem

This is just simple script you can modify it to send output to /var/www/mydomain.com/status dir in plain or html format

Can I gather information like uptime, disk usage? Memory usage? All that? from 3-4 servers and output them on one server? Can you help me, please? Any suggestions are much appreciated.

This website rocks!

Thanks guys,

Yes it is possible, do you have sshd installed on all servers? Or atleast if you shoud allow it as follows:

main-server -> ssh -> Rest of all servers

Let me know then we can create small script for job! Do you like to see output in text or html format?

Hi Vivek!

Yes, I have ssh access on each of the servers and yes, if possible I'd like it in html format so I can design it a bit, not just simple text output.

I'd really appreciate if you could help me out with this!

This website and you guys are awesome! Keep up great work!

Kind Regards,

Okay I have done some work and uploaded file aka script @ http://bash.cyberciti.biz/monitoring...ation.bash.php have a look it at script and try it. You need to setup Following for all your ips:

Code:

Q_HOST="192.168.1.2 127.0.0.1"

It creates HTML code but i'm not good at web or fancy effect.. you can modify it as per your needs. Let me know if you need any other stuff into it.

You need to setup the ssh keys based authentication to avoid the password prompt see http://www.cyberciti.biz/nixcraft/vi...entication.php

Once done that you can run the script as follows

geninfo.bash > /var/www/html/output.html

And test it into browser using http://www.mydom/output.html

Hope this helps!

OMG It works WONDERFUL! I had to copy id_rsa.pub to authorized_keys2 on localhost (127.0.0.1) but it works wonderfully! Thank you sooo much Vivek!

I thought it would be easy to modify the html layout, but it's not quite easy. Would it be too much if I'd ask how can I output this in a table with 3 columns? (I have 3 servers).

Something like

I hope you know what I mean and hopefully this can be done.

Thank you so much!!

Okay done

See url http://cyberciti.biz/tmp/geninfo.bash.txt
And download files http://cyberciti.biz/tmp/graph.gif
http://cyberciti.biz/tmp/indicator.gif

Rest of the info is same!

Let me know if this works or not!

Enjoy!!!

IT WORKS! I can't believe I finally have a status script the way I like it! Thank you so much!!!! If you wish, I can PM you the statistics URL so you see it!

Thank you again Vivek! You rock!

Script looks quite complicated to me? How it digs out information from other hosts? Will it works with FreeBSD or Solaris UNIX?
