Go Agent v0.2.2

June 21, 2023

  • Change Modified the agent configuration method.

    • The whatap.conf files are now configured for each process.

    • The whatap.conf file must have been created before running the process.

    • The previous /usr/whatap/agent/whatap.conf file uses only the whatap-agent service.

    Note

    • It is recognized as an agent for each process for data separation.

    • In the past, multiple processes were all recognized as an agent, and their data was integrated.

    Tip

    For more information about agent configuration, see the following.

  • Change For agent IPC communication, UDP has been changed to TCP.

    • The net_udp_host and net_udp_port options remained without change.

    • The added net_ipc_host and net_ipc_port options are available.

    By default, the IP of 127.0.0.1 and the port number of 6600 are used. For update, change the user application and the whatap-agent service configuration file. The changes are applied after restarting.

    1. The whatap.conf file of the user application has been changed.
    whatap.conf
    # Change the host.
    net_ipc_host=127.0.0.1
    # Change the port.
    net_ipc_port=6601
    1. The whatap.conf file of the whatap-agent service has been changed.
    vi /usr/whatap/agent/whatap.conf

    # Change the port. 
    net_ipc_port=6601
    1. Restart
    service whatap-agent restart

  • Change The agent naming convention has been changed.

    • Previous: {type}-{ip2}-{ip3}-{process}

    • Now: {type}-{ip2}-{ip3}-{cmd}-{cmd_full}

    Note

    • {cmd}: Process name. The value of the executable args[0].

    • {cmd_full}: All the lines of the commands are hashed. All of the executable args.

    • When using the same process and arguments, the agent name can be duplicated. The app_name option can be arbitrarily set in whatap.conf. For more information, see the following. After configuration, be sure to restart the application.

  • Change Modified the memory usage.

    The memory usage appears with the sum of HeapInUse and StackInUse in runtime.MemStats.
