    An error appears in the log when monitoring DB port

    Zabbix Server 3.0.22 (CentOS7.5)
    DB : MySQL 5.6.40

    I am monitoring the DB(MySQL 5.7.12) port at Zabbix Server.
    However, the following error is output to the monitoring target DB, and I am in trouble.

    Steps to reproduce:
    1. Register the host of the target DB.
    2. Set the item key using 「net.tcp.service」or 「net.tcp.port」.

    Result:
    The following errors are output at the item acquisition interval in the error log of the monitoring target database.

    2019-03-14T04:37:23.750629Z 10196 [Note] Aborted connection 10196 to db: 'unconnected' user: 'unauthenticated' host: '10.51.43.31' (Got an error reading communication packets)

    10.51.43.31:Zabbix Server IP

    Open the port specified during installation and restart the agent. If necessary you can monitor outside the firewall using an SSH tunnel tellthebell.
