   • Stop Collecting Data Through Bytecode Instrumentation

     Enable or disable this function as required. Data such as JVM metrics will always be collected using MBeans. The default value is No.

     Note: When the Stop Collecting Data Through Bytecode Instrumentation option is enabled, data will no longer be collected through bytecode instrumentation. Data such as JVM, GC, and Tomcat thread metrics can still be collected using MBeans.

   • Slow Request Threshold

     If this threshold is reached, more samples will be collected during intelligent sampling. The default value is 800.

   • Max. Collected Data Rows

     If this value is reached, data will not be collected to prevent excessive memory usage. The default value is 500.

   • Slow Request Threshold

     If a request exceeds this threshold, it is recorded as a slow SQL request.

   • Web Monitoring Aggregation

     If this function is enabled, aggregation will be implemented by URL or API based on the rules you have configured.

     1. Click Setting.
     2. On the displayed page, click the URL Aggregation or API Aggregation tab.
     3. Click Add Rule.
     4. In the displayed dialog box, set parameters.
