scripting: system-help

We have this handy script at work that pulls all kinds of useful details from a system and saves us a ton of time checking by hand, so I took a stab at making my own version for generic use. Its not very good at all but it kinda works and probably could be expanded upon to do something actually useful.


# things to check
# internal ip, external ip, dns server, connectivity to google
# filesystem usage, current system load, memory usage

> log.log
date >> log.log
IP=`ip addr | grep -P -o 'd{1,3}.d{1,3}.d{1,3}.d{1,3}/24'`
EXT_IP=`curl -s | grep -o -P 'd{1,3}.d{1,3}.d{1,3}.d{1,3}'`
DNS_1=`grep -P -o 'd{1,3}.d{1,3}.d{1,3}.d{1,3}' /etc/resolv.conf`

echo "Internal IP:" $IP >> log.log
echo "External IP:" $EXT_IP >> log.log
echo "DNS Server 1:" $DNS_1 >> log.log

MEM_USAGE=`free -m`
echo -e "nMemory Informationn" >> log.log
echo -e "$MEM_USAGE" >> log.log 

DISK_USAGE=`df -h`
echo -e "nDisk Usagen" >> log.log
echo -e "$DISK_USAGE" >> log.log

TOP_SNAPSHOT=`top -n 1 -b`
echo -e "nTop Processesn" >> log.log
echo -e "$TOP_SNAPSHOT" >> log.log

echo -e "nUptimen" >> log.log
echo -e "$UPTIME_SNAPSHOT" >> log.log

# now lets try some active tests
echo -e "nPing Testn" >> log.log
if eval "ping -q -c 1> /dev/null"
	echo -e "Ping Test: Successful!" >> log.log	
	echo -e "Ping Test: Failed!" >> log.log
