Shell script- need help

Hi below is my current scripting which will monitor for any errors in the application

logfile="/tmp/application.log"
output=$(grep "ERROR" $logfile)
if [ -n "$output" ]
then
echo "found- send email"
else
echo "not found"
fi

Now I wanted the script NOT TO MONITOR for one of the occurence of the error which is a known issue
Could you please help me as how can I set this up
The error string I wanted to EXCLUDE from monitoring is below

" ERROR - Error while reading from socket
java.net.SocketException: Connection reset "

just change

output=$(grep "ERROR" $logfile|grep -v "pattern that u don't want to match")

man grep:

-v, --invert-match
Invert the sense of matching, to select non-matching lines. (-v
is specified by POSIX.)
