Statistics view
Statistics, as the name implies, provide a quick overview of the important values of a capture. There are two columns: global and snapshot. Global represents the statistics on the entire timeline and snapshot displays statistics of the selected time slice. The snapshot column is dynamically updated during the selection in the memory timeline.
Below you can find more details about each of the rows:
Usage
The amount of memory used, in bytes, at the end of the time slice. This is basically unreleased memory and for global column represents the amount of leaked memory.
Usage peak
Represents peak memory usage, in bytes.
Operations
Total number of memory operations.
Allocations
Number of allocations, this includes both regular and aligned allocations.
Reallocations
Number of reallocations.
Frees
Number of released memory blocks.
Live blocks
Number of memory blocks that are live at the end of time slice.
Overhead
Memory allocation overhead, in bytes, at the end of time slice.
Overhead peak
Maximum memory allocation overhead, in bytes.
