Server Inventory Bash Script Thoughts...

Hi LQ,

I am writing a bash script to perform pre and post patching collection of server information for the purposes of diagnosing and rolling back anything that may break during a patch. This is going to be used on multiple different server configs most of which are configured in their own proprietary way.

I already have a rough draft created that gets most of the info you would think of, rpms installed, fstab, running procs, etc..

I was looking to see if anyone out there had any thoughts or knew of any pre-existing scripts that I could reference to make my life easier.

Basically, I'm asking if anyone can give me some input on info that should be collected when during a server inventory run just to make sure I don't forget or overlook something.

Which distro are you using?
If RedHat/Centos I recommend following commands:

List of patches:

Code:

[root] # rpm -qa --last

And then gather this info for general configurations/information about system :

For General Configuration Information:

Code:

uname -a

cat /etc/redhat-release

cat /etc/sysctl.conf

cat /etc/fstab

cat /etc/hosts

cat /etc/passwd

cat /etc/group

cat /proc/meminfo

cat /etc/grub.conf

cat /etc/resolv.conf

cat /etc/nsswitch.conf

cat /proc/mdstat

crontab -l

services --status-all

Disk/Fiber Info:

Code:

sfdisk -l /dev/sda

systool -c fc_host -v

systool -c fc_transport -v

mdadm -D /dev/md0

pvdisplay

vgdisplay

lvdisplay

Filesystem/Network/Memory Info:

Code:

df -h 

ifconfig -a

netstat -rnv

free

vmstat

For script you could do something like this:

Code:

for CMD in "

cmd1

cmd2

cmd3 ...etc"

do

echo "##########"

echo "Output from: $CMD"

echo "##########"

(${CMD})

echo ""

done

Thanks for the pointers, I had most of the commands in my script already but you definitely highlighted a few that I didn't think about and will work on implementing.

Thanks again.
