UNIX: check CPU usage and disk usage

Script to check cpu usage

grep 'cpu ' /proc/stat | awk '{usage=($2+$4)*100/($2+$4+$5)} END {print usage "%"}'

#!/bin/bash

limit=2
email_destination="whatever@gmail.com"
email_body="WARNING the CPU usage on server `hostname` exceeded the limit you set ($limit)%"
email_subject="WARNING cpu usage"

usage=`grep 'cpu ' /proc/stat | awk '{usage=($2+$4)*100/($2+$4+$5)} END {print usage}' | bc`

if echo $usage $limit | awk '{exit $1>$2?0:1}'
then
  echo -e $email_body | mail -s "$email_subject" $email_destination
  #echo 'alarm'
fi

Disk space not updating in linux df -h after deleted files

ls -ld /proc/*/fd/* 2>&1 | fgrep '(deleted)'


restart the process that hold it

UNIX: sum and print total content of file

$ cat tpsCCRT.txt | awk '{sum+=$1} END {print "Count: ",NR;print "Avg :",sum/NR}'
Count:  1441

How to upgrade the firmware using SSH

The following commands can be used to upgrade the firmware on an HP iLO or iLO2 interface. This procedure is particularly useful when the iLO stops working properly and it's not accessible from the server or via HTTP(S).

Use the following procedure:

    * Use SSH to access the iLO device
    * Log in to the iLO using administrative credentials
    * Type the following command and press enter: "load -source http://ip_address/path/imagename.bin /map1/firmware"
          o  Example: "load -source http://192.168.0.1/ilo2_180.bin /map1/firmware"
    * The interface will download the new image and will reset itself
    * To check the firmware version, log in again using SSH and enter the following command: "show /map1/firmware version"
