Linux script to collect system statistics and send to your email

Yet another shell script to collect the system stats from your *Nix server and send them to your mailbox without any hassle.  You may have to modify the script based on the shell type (zsh/ksh/bash).

	#!/bin/bash
	SERVER="mydomain.com"
	EMAIL_TO="your_email@gmail.com"
	EMAIL_FROM="stats@mydomain.com"
	# logged in users and what are they running
	WHO=`w`
	# processor stats
	MPSTAT=`mpstat`
	# virtual memory stats
	VMSTAT=`vmstat`
	# Top 20 memory hog applications
	PS_MEM=`ps -A -o pid,pcpu,pmem,start_time,state,time,comm | perl -e '($_ = join "",<>) =~ s/(\t)/ /g; print;' |sort -g -k 3 -r | head -20`
	# Top 10 CPU usage applications
	PS_CPU=`ps -A -o pid,pcpu,pmem,start_time,state,time,comm | perl -e '($_ = join "",<>) =~ s/(\t)/ /g; print;' | sort -g -k 2 -r | head -10`
	# memory usage in MB
	FREE=`free -m`
	PROCINFO=`procinfo`
	# iptables status
	IPTABLES=`iptables -nL`
	# established connections
	NETSTAT=`netstat -na |grep -i esta |grep -v 127.0.0.1 |sort -n -t. -k2`
	# line divider
	DL="=================================================================================="
	FINAL="${DL}
	`date`
