Agent communication settings

The following provides the method how to set the communication for the Go application server.

  • whatap.server.host ip_address

    Default 127.0.0.1,127.0.0.1

    Set the server to deliver the agent's collected data to. If there are multiple IPs due to the collection server redundancy, they can be specified by separating with comma (,). The collection server's proxy daemon must be serviced in the listening state for the specified IP.

  • whatap.server.port tcp_port

    Default 6600

    Set the port of the collection server. Because only one port can be specified, the collection servers specified in whatap_server_host must use the same port.

  • tcp_so_timeout Millisecond

    Default 60000

    Set the socket timeout of the TCP session that communicates with the collection server.

  • tcp_connection_timeout Millisecond

    Default 5000

    Set the connection time out of the TCP session that communicates with the collection server.

  • net_send_max_bytes Byte

    Default 5242880

    Set the maximum size of the data to send to the collection server at one time.

  • net_ipc_host ip_address

    Default 127.0.0.1

    It is the agent's TCP address for sending the data collected by the application via IPC/TCP to the agent. It is not recommended, but use this option when the agent is running on an external server.

    Note

    To apply the settings, restart the application.

  • net_ipc_port tcp_port

    Default 6600

    The WhaTap agent transfers the data collected by the tracer to the collection server via IPC/TCP. You can specify the port of the initial TCP server. If the provided port 6600 is in use, you can use this option. To change the TCP server port of the agent, modify in the /usr/whatap/agent/whatap.conf file path.

    Note

    • If the server port has been changed, update it also in the whatap.conf file of the application to establish the communication.

    • To apply the settings, restart the application.
