! # / Bin / bash
recvflag = ''
recvcount=`netstat -lntp |grep 18888 | awk -F' ' '{print $2}'`
proid=`ps -ef |grep [f]pMessageSend | awk -F' ' '{print $2}'`
datetime=`date +"%Y-%m-%d %T"`
if [ $recvcount -gt 0 ]; then
    recvflag = 1
else
    recvflag = 0
be
echo $datetime Recv-Q:$recvcount Recv-Flag:$recvflag >> /tmp/fpMessageSend.log

if [ $recvflag -eq 1 ]; then
    #kill -9 $proid
    sleep 1
    #systemctl restart fpMessageSend_92360424L562938299_0.service
    if [ $? -eq 0 ]; then
