System data gathering super mega script

I'm running this script on a Linux box to gather info on the processes it is running, besides, of course, Nagios.
That box was having a problem that sometimes, totally random stuff, the network went down, this particular box has two NICs, but I can access it only thru SSH, so, went the net went down, I lost the box completely.
Ever since I started to run the script, this system stopped having troubles...
An option I have considered was using a software Watchdog, but I'm not that convinced on running one.


#!/bin/sh
# Data gather script (Modified from one found on Internet)
# /root/devel/dataGathering/system-snapshot.sh
# Be sure to run logrotate on $LOG (!)
