        • 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 list form
      • Default sorted in descending order by Self Consumption
    • Simultaneous Selection: View performance profiling data in both Flame Graph and Table forms 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
