Automatic Parameter Tuning Interface

Click the Auto tune button in the configuration editing area in the middle of the one-click configuration interface to enter the automatic parameter tuning interface, as shown in Figure 1. Currently, only dynamic tuning of local parameters is supported.

Figure 1 Automatic parameter tuning interface

**Table 1** Automatic parameter tuning interface
Area	Name	Description
1	Information area	Displays the tool name and workspace path. You can view help and log information, exit the tool, and return to the one-click configuration interface.
2	Dynamic parameter configuration area	Supports configuring dynamic tuning parameters and ranges.
3	Tuning task area	Supports querying, stopping, and configuring results of automatic tuning tasks.
4	Dependency parameter area	Allows you to configure dependency parameters. Some parameter configurations have dependency parameters. For example, BIOS parameters depend on the BMC IP address, user name, and password, and Spark service parameters depend on the Spark configuration file path.
5	Tuning task configuration area	Supports configuring automatic tuning information, such as the log level, number of tuning rounds, random sampling round ratio, and tuning direction.
6	Functional area	Supports specifying the performance test script file (SCRIPT_PATH) and automatic parameter tuning.
