Basic monitorization

Filesystem usage

#!/bin/bash
export data=`df -h |awk {'print $5 "@" $6'}|grep -v Use|sed 's/%//g'`
export result=""
for value in $data
do
export number=`echo $value|cut -d @ -f1`
export filesys=`echo $value|cut -d @ -f2`



if [ $number -gt 80 ]
then
result="${result} ${filesys}"
fi
done




export count=`echo $result|wc|awk {'print $2'}`
if [ $count -eq 0 ]
then
exit 0
else
echo $result
exit 1
fi

Cpu and memory usage per process

ps -eo pcpu,pid,size,vsize,user,cmd|sort -k 1 -r|head -10
