Script required for Top usage remotely

rajaniyer123 · 08-02-2008, 03:12 PM

Hi

As I would like to know the script or command by which I can get below mentioned o/ps from all solaris servers remotely, without login into all servers. Note : the below o/p is from top command.

load averages: 1.14, 1.07, 0.91 16:03:53
87 processes: 85 sleeping, 2 on cpu
CPU states: 58.2% idle, 32.6% user, 9.1% kernel, 0.0% iowait, 0.0% swap
Memory: 2048M real, 367M free, 390M swap in use, 2076M swap free

Thanks
Rajan

Top isn't bundled with Solaris. Assuming you have it installed on all hosts, you can run a script like that one:

Code:

for i in server1 server2 server3
do
  echo ==== $i ====
  ssh $i /usr/local/bin/top | head -4
done

You also need to have public key authentication configured for the user running the script to avoid password prompting.

If you do not care about security, you can use rsh instead of ssh.

Why not use something like nagios instead? If you really must go the remote script route and you are using solaris 8 or above, use prstat instead, its footprint is much lighter.

prstat doesn't displays the set of statistics the OP is asking for. You would need a combination of several standard commands to provide them.

OK fair enough. Still, I wouldn't bother with top on a solaris box as it'll further skew any stats you get back. Also, he's probably got the system activity reporter service running in the background anyway so no harm in using sar too, e.g.

Code:

prstat -t 1 1 | grep -v ^$; sar -r 1 1

If you're running sol 10 then you can get even better, more specific results using dtrace.

Anyway, what do you do with all this ascii once you've collected it? Save yourself some time in the long run and install some decent monitoring software. You'll also find that historical data and decent graphing tools will help you catch problems before they become and issue. My two pennies worth anyway...
