[Ugent] a script of getting some information of my system.

[KCS_1]

Hi,

I am making a script for managing my system and have some difficulties to get under

1. performance

Usage of cpu,momory and disk

2. Kernel table values

nproc,nfile,ninode and shared memory

3. etc

Network collision and Total installed memory in my system.


Would you help me how to get these informations on the prompt command line?


Thanks

For me, cpu, memory and disk can be summed up with the load average in "uptime -a". It doesn't tell you what is wrong BUT if the load average is low you don't need to bother to find out.

sar is good for your other performance issues.

netstat -in shows network collisions

I THINK you can get all you kernel parameters from /stand/build/tune.h though you can't use this file to modify them.

Amount of memory I get from a little C program that uses "pstat" however, other people here have funky "adm" command lines that will do the job and will almost certainly be posted in a minute if they haven' already while I've been wittering on.

2. kmtune -q nproc

3. You can get a lot of ready made scripts from: favorite sysadmin scripts threads,
