Overview
Down and dirty mini status viewer. Makes it easy to monitor several different sections of a server at the same time.
Useful for monitoring a server that is having problems.
The main concept is to minify the output of several sections in to a small terminal window, useful for monitoring a server when it is having problems or could at some point.
Auto adjusts output based on size of the terminal.
Script
[bash,n]
cmdmysql=`mysqladmin proc stat | grep "|" | grep -v "Id" | awk 'BEGIN{FS="|"};{print $7,$6,$9}' | sort -n`
wcmysql=`echo $cmdmysql | wc -l`
nline=`tput lines | awk '{print int(($1 - 18) / 2)}'` if [ $nline -gt $wcmysql ] then
nline=`echo $nline $wcmysql | awk '{print $1 * 2 - $2}'`
