Valgrind: Valgrind is a tool framework for building dynamic analysis tools. There are some Valgrind tools that automatically detect many memory management and threading errors and analyze your program in detail. You can also use Valgrind to build new tools. The Valgrind distribution currently includes 7 product quality tools: a memory error detector, two thread error detectors, a cache and branch prediction analyzer, a call graph generation cache and branch prediction analyzer, and two different heap analyzers. It also includes an experimental SimPoint basic block vector generator.
AddressSanitizer: Memory detection tool produced by Google
a. Use free and top first to view the overall memory usage of the system.
b. Use vmstat and pidstat to view memory changes and determine the memory problem type
c. Detailed analysis, such as memory allocation analysis, cache/buffer analysis, memory analysis of specific processes
