A perfect way to collect error in a log file ( the erroe is the camera disconnectand and connect again in IVS )

Using the ping.sh attached

Running the script Steps：
        Step1： Change the IP address of script ping.sh to the error camera IP.
        Step2:   update ping.sh to the server /home/admin/
        Step3:   input command:  chmod +x  /home/admin/ping.sh
        Step4:   running the scrip,  input command: nohup  /home/admin/ping.sh &
        Step5:   When the problem happened, script will record result to /opt/ping.log
        Step6：  Stop the  scrip input command: PID=$(ps -ef|grep ping.sh | grep -v grep | awk '{print $2}')
                           kill -9 $PID
