Quick CentOS Inventory Script

Had a need to quickly grab inventory (sys config) information from a bunch of hosts on our network. Unfortunately, identifying the number of CPUs/cores and specific drive information isn't always clear cut. This script grabs the key information, which can be used to discern the basic system configuration.

A couple of notes:
1. This is CentOS or RedHat specific. Your mileage will vary with other flavors.
2. At the time of this post, all of our systems are using SCSI drives and the script only grabs SCSI disk info from dmesg.

#!/bin/bash
clear
echo "##################### SYSTEM INVENTORY ########################"
grep HOSTNAME /etc/sysconfig/network
cat /etc/redhat-release | awk -F "&&&" '{print "OS VERSION: " $1}'
echo
echo "NETWORK INFO:"
echo "#################################################################"
/sbin/ifconfig | grep -A1 eth0 |grep "inet addr" | awk '{print $2}' |awk -F ":" '{print "ETH0 IP ADDRESS: " $2}'
/sbin/ifconfig | grep -A1 eth1 |grep "inet addr" | awk '{print $2}' |awk -F ":" '{print "ETH1 IP ADDRESS: " $2}'
echo "#################################################################"
echo
echo "CPU INFO:"
echo "#################################################################"
cat /proc/cpuinfo |egrep "processor|model name|cpu MHz|physical id"
echo "#################################################################"
echo
cat /proc/meminfo | grep MemTotal | awk '{print "SYSTEM MEMORY: "$2"KB"}'
echo
echo "HARD DISK INFO:"
echo "#################################################################"
dmesg | grep SCSI | grep MB
echo
df -lTh
echo
echo "##################### END OF INVENTORY ########################"
exit 0
