Rotate Right Zoom - Call Tree Visualization

Call Tree Visualization

Symbol information is used to map program addresses to symbol names. Breaking down a profile at symbol granularity is a useful way to understand the time spent in blocks of code. There are a variety of methods for summarizing the information in a set of samples that include backtraces of each sample's call stack:

  • Top-down (tree) visualization is used to find "hot" (frequently sampled) call paths, starting at the root symbol (e.g. main).
  • Bottom-up (leaf) visualization is used to find "hot" code, starting in the symbols where samples occurred.
  • Hotspot visualization is a complete list of symbols encountered in the profile that is used in conjunction with a side-by-side tree and leaf views (butterfly view). Selecting a symbol in the hotspot list shows the callers and callees of that symbol in the butterfly view.

Famous quotes containing the words call and/or tree:

    Wherever there are walls I shall inscribe this eternal accusation against Christianity upon them—I can write in letters which make even the blind see ... I call Christianity the one great curse, the one great intrinsic depravity, the one great instinct for revenge for which no expedient is sufficiently poisonous, secret, subterranean, petty—I call it the one immortal blemish of mankind....
    Friedrich Nietzsche (1844–1900)

    If the tree is straight it need not fear casting a crooked shadow.
    Chinese proverb.
