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]
- !/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 'BEGIN {FS="|"}; { printf "%-4s%-18s%-8s%-30s",$3,$1,$2,$4; print "" }'` if $cmdmysql != "" then wcmysql=`echo "$cmdmysql" | wc -l` else wcmysql=0 fi return } function checkapache { if [ -d "/var/cpanel" ] then cmdapache=`httpd status 2>&1 | sed -n '/requests\/sec/,/Scoreboard/p' | sed 'N;$!P;$!D;$d' | grep "requests/sec" -A 999` else cmdapache=`lynx --dump http://localhost/server-status 2>&1 | sed -n '/requests\/sec/,/Scoreboard/p' | sed 'N;$!P;$!D;$d' | grep "requests/sec" -A 999` fi if $cmdapache != "" then wcapache=`echo "$cmdapache" | wc -l` else wcapache=0 fi return } function calclines { nline=`tput lines | awk '{print int(($1 - 14) / 3)}'` aline=`echo $nline 3 | awk '{print $1 + $2}'` if [ $nline -gt $wcmysql ] then nline=`echo $nline $wcmysql | awk '{print $1 * 2 - $2}'` fi return } function addseperator { printf "%$(tput cols)s\n"|tr ' ' '=' return }
