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.
