1. Continuous Profiling

For the functional principles, see Core Features - Explanation of Continuous Profiling

1.1 Overview Introduction

Overview Introduction

• ① Page Search: Search bar, search snapshots, and other functions. For details, please refer to the chapter Tracing - Resource Analysis
• ② Quick Filter: Supports filtering by Application List and Profiling Type
  • Application List: Displays the reported service list information, with the default display format as Service Name (Language Type)
  • Profiling Type: Displays the Profiling Type supported by the profiling method configured on the client
    • Select the Profiling Type supported by the current application, different profiling types represent different semantics
• ③ Display Switch: Switch the display mode of performance profiling data. Currently supports: Flame Graph, List, and Simultaneous Display
  • Flame Graph: Displays the function call stack in the form of a flame graph
    • ⑥ Tip: Hover to view information about the Span in the flame graph
      • Function Type:
        • K: Linux kernel function
        • L: Function in a dynamic link library
        • A: Business function of the application
        • P: Process
        • T: Thread, only appears in the second layer of the flame graph
        • ?: Unknown, function name translation failed. For detailed explanation, see Core Features - Continuous Profiling - Viewing Data - About Function Type
      • Span Name
      • Total Consumption: The percentage of total consumption of the Span relative to the root (the first line of the flame graph)
      • Self Consumption: The percentage of self-consumption of the Span relative to the root (the first line of the flame graph)
    • Operation: Click to zoom in and view the call stack of the clicked Span; click again on a blank area to return to the original state
  • Table: Displays the function's Self Consumption and Total Consumption in a list format
    • Default sorted by Self Consumption in descending order
  • Simultaneous Selection: View performance profiling data in both Flame Graph and Table formats simultaneously
    • Clicking on a function in the table will highlight it in the flame graph
• ④ Flame Graph Name Display: The flame graph can choose to display the head or tail of the name
• ⑤ Data Filter: Input characters to filter data in the table
