For the working principle, see Core Features - Continuous Profiling Description

1.1 Overview

Overview

• ① Page Search: Search bar, search snapshots, and other functions. For usage details, please refer to the section Tracing - Resource Analysis
• ② Quick Filter: Supports filtering by Application List and Profiling Type
  • Application List: Displays the list of reported services. The default display format is Service Name (Language Type)
  • Profiling Type: Displays the Profiling Types 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, Table, and Both
  • 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: Application business function
        • P: Process
        • T: Thread, only appears on the second layer of the flame graph
        • ?: Unknown, function name failed to translate. For detailed explanation, see Core Features - Continuous Profiling - Viewing Data - About Function Type
      • Span Name
      • Total Consumption: Percentage of the Span's total consumption relative to the root (first row of the flame graph)
      • Self Consumption: Percentage of the Span's self consumption relative to the root (first row of the flame graph)
    • Operation: Click to zoom in and view the call stack of the clicked Span; click on a blank area to return to the original state
  • Table: Displays Self Consumption and Total Consumption of functions in a list format
    • Default sorting is in descending order by Self Consumption
  • Both: View performance profiling data in both Flame Graph and Table formats simultaneously
    • Clicking a function in the table will highlight it in the flame graph
• ④ Flame Graph Name Display: Choose whether to display the head or tail of the name in the flame graph
• ⑤ Data Filter: Enter characters to filter data in the table
