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
#!/bin/bash
function checkmysql {
cmdmysql=`mysql --batch -e 'show processlist;' | grep -v "Id" | cut -f6,5,4,8 | sed -e 's/\t/ /g' | sort -nr --key=3 | sed -e 's/ /\|/' -e 's/ /\|/' -e 's/ /\|/' | awk -v termwidth="$termwidth" 'BEGIN {FS="|"}; {termwidth=termwidth - 39; query=$4; query=substr("'"${query}"'",1,termwidth) }; { printf "%-3s%-17s%7-s%-" termwidth "s%-1s",$3,$1,$2,$4,query; print ""; }' | sed '/^$/d' `
if [[ $cmdmysql != "" ]]
then
wcmysql=`echo "$cmdmysql" | wc -l`

wcmysql=0

Usage
Direct download and execution of script (auto mode) from ent.int server:
[bash,n]wget http://scripts.ent.liquidweb.com/ministat -O ministat; watch sh ministat; rm -f ministat
Direct download and execution of script (auto mode) from this server:
[bash,n]wget http://svn.jamesdooley.us/svn/JDooley/Ministat/ministat.sh -O ministat; watch sh ministat; rm -f ministat
