Take a look at some code that I wrote. this would give you the if then part.
Code:
if [ $? -eq 0 ]; then  # check the exit code
        echo "$ip is up" >> /root/Desktop/iplog #write  the ip of the hosts that are up
       
    else
        echo "$ip is down" # will show on the screen the ips that are not up
        logger -p auth.notice "$ip is down" # will write the down host to syslog
        echo "$ip is down" | mail -v -s alert user@anydomain.com > /dev/null 2> /dev/null #will send mail users about host down
    fi

Code:
# tail -f logfile | grep "house server (def" | awk '{
print $1
print $2
print $3
print $4
print $5
print $6
print $7
print $8
}'
what is problem here?

I'd try more like
Code:
tail -f logfile | grep "house Server" |awk '{print $5 $6}'
noting that you said you wanted fields 5 & 6 earlier. Also, tricky to tell without seeing the err msg/output you got, but I'd expect that the '(' caused an issue as it's a 'Special Char' in shell scripting.
Also, *nix is case sensitive, so 'server' != 'Server'.

nope still not working..

ps: i was just using it for testing purpose as if i can get the argument, then i can manipulate them which is why i used "server" instead of "Server"
