Not a bad MOTD script
« on: April 02, 2017, 07:13:09 PM »
First of all to install few things needed for the script (mostly needed if you have minimal install):
Code: [Select]
yum -y install bc lm_sensorsThis script was made very long time ago for one of my FreeBSD servers. Now it`s changed a bit with added functions.
Now the script:
Code: [Select]
#!/bin/bash
#Server Status Script
#https://www.born2host.com
#CPU info
cpumodel=`cat /proc/cpuinfo | head -20 | grep "model name"| awk '{print $4, $5, $6, $7, $8, $10 }'`
core0=`sensors -u | head -11 |grep "temp1_input"| awk '{print $2 }' |awk '{printf("%d\n",$1 + 0.5);}'`
core1=`sensors -u | head -20 |grep "temp2_input"| awk '{print $2 }' |awk '{printf("%d\n",$1 + 0.5);}'`
core2=`sensors -u | head -30 |grep "temp3_input"| awk '{print $2 }' |awk '{printf("%d\n",$1 + 0.5);}'`
core3=`sensors -u | head -40 |grep "temp4_input"| awk '{print $2 }' |awk '{printf("%d\n",$1 + 0.5);}'`
Load1=`cat /proc/loadavg | awk {'print $1'}`
Load5=`cat /proc/loadavg | awk {'print $2'}`
Load15=`cat /proc/loadavg | awk {'print $3'}`
#Users info
user=`whoami`
psa=`ps -Afl | wc -l`
psu=`ps U $user h | wc -l`
#System update need
yum=`yum list updates -q | grep -vc "Updated Packages"`
#Uptime
btime=`last -x | grep reboot | tail -n 1 | awk '{print $1, $2, $6, $7, $8}'`
uptime=`cat /proc/uptime | cut -f1 -d.`
upDays=$((uptime/60/60/24))
upHours=$((uptime/60/60%24))
upMins=$((uptime/60%60))
upSecs=$((uptime%60))
#RAM
mfr=`free -m | head -n 2 | tail -n 1 | awk {'print $4'}`
mfc=`free -m | head -n 3 | tail -n 1 | awk {'print $3'}`
mtc=`free -m | head -n 2 | tail -n 1 | awk {'print $2'}`
swap=`free -m | tail -n 1 | awk {'print $3'}`
#Disk
raid=`cat /proc/mdstat |grep Personalities`
disk=`df -h | awk '{ a = $4 } END { print a }'`

The script will put all the information in /etc/motd and it`s a good idea to put that script in your crontab to run every 1 hour for example(if you want every 5min).
After you run the script you can relog to your server or "cat /etc/motd" to see the output. Should be something similar to this:
Code: [Select]
[root@srv1 ~]# cat /etc/motd
